Gasoline dilution proportions for STIHL trimmer

Correct proportions

Most often, when preparing fuel for saw operation, proportions of 1:50 and 1:40 are used. This means that one part of oil is added to 50 or 40 parts of gasoline. Calculations are made as follows: 1 l = 1000 ml, 1000/50 = 20 ml or 1000/40 = 25 ml, that is, in the first case, pour 20 ml into each liter of gasoline, and in the second, 25 ml of oil. If there are no instructions and you do not know the proportions for preparing the mixture, then use the following recommendations:

Tool and oil of the same brand. For example, for a STIHL chainsaw, the ratio of gasoline and STIHL oil will be the same as indicated on the oil container, usually 1:50.
The substances used for the mixture have different brands; the proportion is 1:40.
There is only one brand, but there is no information on the ratio of substances on the oil - it is diluted 1:40.
In the absence of any information about saw and oil, dilute the mixture in a ratio of 1:40. The only thing you need to make sure is that the oil is intended for two-stroke engines.

To run in a new saw, add 20% more oil during the first three fills of the fuel tank. In this case, instead of the ratio 1:50 it will be 1:42, and the ratio 1:40 becomes 1:33. A liter of gasoline will require 24 or 33 ml of oil, respectively. No other break-in activities are carried out with the new saw. Manufacturers advise working only at the highest speeds at all times. After running in the tool, use the usual proportions of 1:50 or 1:40. In some cases, the equipment manufacturer specifies other ratios, for example, 1:25 or 1:32, they must be observed.

Making the mixture: important proportions

When using a two-stroke engine, clean fuel is purchased separately and mixed with oil, often in proportions of 1:50. It is structurally impossible to install an oil pump in such an engine, so pouring uncontaminated gasoline into a chainsaw is strictly prohibited! The manufacturer shows the proportions, quantity and certain brands in the instructions for use.

Gasoline for brush cutters is ninety-five or ninety-two! What's better?

I decided to take a list of numbers of Sadko service centers and call and ask them which gasoline is better: ninety-two or 95! At first I called the western regions, Transcarpathian, Ivano-Frankivsk, Lyuvov regions, the only answer was 92, it has the least amount of additives, the piston and valves will last longer! in Kyiv they said that only 95! in the Sumy region they pronounced 92, also referring to the percentage of additives of 95! In Kharkov they said ninety-two or ninety-five, take it only at a good gas station, only the oil must be of high quality! In Donetsk and Dnepropetrovsk they said it’s better to take 95! AR Crimea ninety-five or ninety-two only at good gas stations!

A friend of mine had a viburnum, so after 100 seven thousand the rings on the 3rd cylinder were worn out, the previous owner drove 92, several motorists said that it was because of gasoline, that it was necessary to pour 95! Now he only fills up on Voga ninety-five!

so I'm ready for a constructive dialogue!

Well, let's start with the fact that you need to open and read the annotation. But I can say in advance (I have a lot of imported equipment) that it says no lower than 92nd. In general, I would recommend it. I don’t know about you in Ukraine, but we don’t have the usual 95th. Only due to additives and chemicals. Suitable for cars, but not for engines with brush cutters or chainsaws. They break on it. That's why I only use 92.

And this is true advice!

The annotation says 92-95! I fill the oil with mobile1 10v30 synthetic as in the instructions! Called Stihl

, in the first one they said that 95 is better, they only use it, it’s better than Okko or Vog, but take the regular 95. In another service they said that the one I trust is better, I drive 92, even UAZ, even Planetka, even Slavuta! in the third service they said that it is better to fill 2-stroke engines with ninety-two, he doesn’t care, but where are the technology valves, two mix and 4mix, they are very picky about gasoline, and there is only 95! so for now I’m more inclined to the usual 95!

And who forbids it? Only later do you find the culprits. Well, why then ask?

I wish to listen to the impartial worldview of a person who operated brush cutters with ninety-two and ninety-five gasoline! So to speak, I wish it will extend its service life!

I also found some information on some forum, so I’m generally confused!

You have a 4T engine with oil in the crankcase, compared to a 2T engine in which lubrication occurs with a gasoline-oil mixture. For you, gasoline is more ordinary. For you, you can fill in 92-95 gasoline of good quality.

PS In Ukraine there is a network of gas stations; their gasoline contains more than 10% alcohol; such gasoline cannot be poured into 2T engines, because oil dissolves very poorly in such gasoline. But cars run completely normally with such gasoline.

This is a good quality gasoline, I’m not sure that we have such gasoline, but VOG is considered the best gas station in the area! I need to know with what gasoline the engine of the lawn mower will work longer, so I doubt it, I ran it in at ninety-two ANP, but then we didn’t have a VOG yet! but later I came across forum messages where Yaroslav one and Bell Amore and any of the bottom substantiated their rightness, and gave certain examples! That's when I started thinking! While creating the topic, I was thinking at the moment the SC dudes would come running here and tell me how much roofing felt is in ODESSA! I still doubt which gasoline !

On good gasoline 92, 95. I realized that your engine is a copy of the Japanese Honda. Answer this question: is there gasoline similar to our 92nd in the Land of the Rising Sun? The fact that 92 is recommended means there is less chance of running into eighty acetone = 95.

Yes, a copy of the GX 30 5 Honda engine! I think the Japs don't have ninety-two! I came up with an idea, if you take a 10 liter canister and fill it with 5 liters of ninety two 5 liters of ninety 5 on Vogue! it will be something like 93! don't judge strictly!

I support it one hundred percent. Even in a car where 95 is registered, you have to fill it with 92. Two-stroke engines from our ninety-five will quickly fail.

so I have a 4t engine!

And I wrote here and there that I have a 2-stroke in my car?

I almost died from laughing.

I didn’t even claim that you have a two-ton engine in your car!

dimasldo, You don’t really bother about gasoline, fill up with a proven one that you trust. For your engine, there is no particular difference between it being 92 and ninety-five, the main thing is that it has high-quality gasoline. You better change the oil more often, it will be healthier for the engine.

Well actually yes. I figured it out from him straight away. And then you shouldn’t bother. Unsullied does not actually deteriorate. I've had it in barrels for years. The mixture with oil spoils.

I worked with the scythe for fifteen hours and have already changed it three times!

Regarding gasoline, I dare to make an objection! It deteriorates, or rather oxidizes and turns yellowish! About 5-6 years ago, my father took 95 gasoline to the Russian Federation, at the moment I have liters left. 30, so he turned yellow, Now he entered the tool center, of Partner Stihl, a guy works there, he has been repairing saws and lawn mowers there for 5 years, he said that gasoline oxidizes and has a bad effect on the piston, scratches appear on the piston! He also said that there is no difference in what gasoline the saw will work on! The main thing is that before pouring gasoline for the day, pour it into a transparent container; if after a day no sediment has fallen out, you can use the gasoline! Demonstrated examples of gasoline that precipitates!

Well, since you understand everything yourself, then why are you asking?

If I didn’t know, I wouldn’t have asked, I didn’t know which gasoline was better, ninety-five or 92, and I knew that it would deteriorate, so I didn’t ask! Thank you very much to those who responded!

Here's another resource I found, it might be interesting! Now for gasoline, the consistency ratio between gasoline and oil has nothing to do with the brand of gasoline. The brand of gasoline only affects engine detonation. Detonation is a spontaneous explosion of gasoline during compression. It exploded and the piston or elbow or connecting rod were destroyed, sometimes the head was cut in half. I'm not trying to scare you, it's just the way it is. About gasoline - imagine a piston moving up the cylinder and compressing the fuel mixture - HOW various gasolines behave during compression: Eighty gasoline gives detonation at a compression ratio of about 8-9 and burns rapidly after a spark, i.e. the piston had not yet reached top dead center, at a compression ratio of 11-12, and the gasoline spontaneously exploded and pressed the piston in the opposite direction and broke down the entire piston. Gasoline ninety-two detonates at a compression ratio of about 11-12 and burns longer than 80 after ignition by a spark. In other words, in terms of compression ratio, it matches our tools - gasoline engines used on the site. Ninety-five gasoline detonates at a compression ratio of about 12-14 and burns even longer after ignition by a spark. but due to the slow combustion of the exhaust gases, it continues to burn and burns the piston and exhaust tract. In addition, in our country, ninety-five gasoline is mostly with additives that increase the octane number and all the additives remain on the spark plug and rings. To obtain enormous power from a small volume, the compression ratio is increased to 10-12, so that the mixture is compressed more strongly beforehand and receives additional power after ignition. All engines of the strimmer, chainsaw, pump - (although it may be 4 stroke) are designed for ninety-two gasoline. Imagine a spark igniting a mixture with ninety-five gasoline, as you know, it burns longer and the combustion process will be prolonged in your muffler, and the fresh mixture that arrives again will partly burn, and part of the piston and rings, towards the exhaust port, will be fried alive fire. And gasoline ninety-two burns before the exhaust phase and only smoke goes into the muffler. As is clear, gasoline does not immediately ignite and expand, therefore, the spark jumps before the piston approaches top dead center, the so-called ignition advance, in these engines it is from 1.5 mm to three mm. In the spring, before the first start, be sure to prepare the engine, after winter everything in the engine is dry and the compression is weak and the dry rings scrape along the cylinder, you can lift the cylinder, to prevent this from happening, I spray honey. with a syringe into the spark plug hole, about two cubes of consistency, from time to time more, I crank the engine slowly, try to start it, but it doesn’t start, since the freshest mixture settles on the dry walls of the crankcase and does not enter the cylinder, if there is a consistency enricher, turn it on, or again unscrew the spark plug, check it, if necessary, blow it out and again use a syringe to put the mixture into the cylinder, about two cubes, it will sneeze and start, then warm it up and the tool is ready for use for the whole season. I’ll add on my own behalf: Pour ONLY what is written in the manual! Ninety-five is no better or worse than 92 - they are just different! Even the sick ones!

Chainsaw device

Each chainsaw has different technical specifications and can perform different jobs.

Powerful saws are suitable for felling centuries-old trees; small-format chainsaws are more suitable for performing various tasks in the household:

Standard chainsaw blocks:

Power point.
Clutch.
Ignition unit.
Carburetor.
Fuel block (tank for oil and fuel).
Filters for cleaning incoming air.
Starter.
Chain.
Tire.
Chain brake.
Tension mechanism.
Element that provides chain lubrication.

Each chainsaw requires high-quality fuels and lubricants; they ensure long-term productive operation of the unit. What kind of gasoline should I fill in for a chainsaw, in what proportions?

For domestic chainsaws, simple oils are suitable; foreign chainsaws need more complex fuel mixtures that have been thoroughly cleaned.

Advantages and disadvantages of oil

Any high-quality engine oil has its pros and cons

Any high-quality engine oil has its pros and cons. Some experts say that any chainsaw oil will do. This is not entirely true; almost any substance can be used for the Hurstavna chainsaw, but only gear oil is required for the STIHL . When choosing, you need to know the color of the oil well; a two-stroke engine requires a composition that has a reddish, bluish or greenish tint.

READ How to Put Line on a Husqvarna Trimmer

To prepare the mixture yourself, you need to use a heat-resistant lubricant that has a well-known brand.

The density of the product is affected by seasonality:

Solar radiation intensity.
Pressure.

You can find out what the features of different oils are by carefully studying the label on the container. If there are no instructions or labels on the package, you should refuse to use such a substance. At the same time, the performance characteristics of oils should not change dramatically when temperature conditions change.

You should not use any substitutes; counterfeit products are often found among them (up to 20%). It is quite difficult to distinguish a fake; you need special equipment.

It is recommended to store fuel in metal containers. It is best to prepare the fuel mixture in a canister.

There are a large number of oils and each has its own characteristics

The consistency is made in the ratio:

The performance characteristics of mineral or organic oil intended for the chain itself are not suitable for preparing the fuel mixture. The container is filled with the finished product (up to half), then mixed (the container must be hermetically sealed). Thus, a homogeneous composition is obtained. It is better not to prepare the fuel ahead of time; it quickly loses its functional properties. At room temperature, flammable liquids deteriorate within two weeks.

Helpful Tips:

From time to time it is better to add a little oil, if you regret it. If you give a little more oil than indicated in the instructions, then nothing terrible will happen. The formation of carbon deposits can occur in cases of a huge amount of oil and if the indicated proportions are not observed;
It is better to store the finished mixture for a month and no more, because for some reason it will lose its properties;
Proper completion of work. Be sure to use or drain the contents of the tank, this way you can extend the life of the rubber and plastic seals;
You should not use oil designed for mopeds for a chainsaw, because it is designed for low speeds.

The correct operation of your equipment depends entirely on you. Firstly, do not disdain the manufacturers' instructions or, in the latter case, the instructions on the oil packaging. This will help you avoid unpleasant situations. The neighbor does not always know what is best to do. The cheapness of oil and gasoline is not an indicator of the highest quality, because tool failure can cost much more (approximately eighty% of the price of a chainsaw) than the savings on fuel consistency

facilities.

STIHL chainsaw: what gasoline oil should I use?

A number of manufacturers producing equipment also produce their own consumables, which are adapted to the operation of a specific engine. Likewise, STIHL produces oil exclusively for its equipment. It is equipped with special additives that can compensate for the quality of the fuel, improving lubrication and cleaning of the fuel mixture. It should be noted that Husqvarna HP oil is universal and can be used for any chainsaw. It can be used at temperatures not lower than 10 degrees.

The following brands are also used for two-stroke engines: Sadko, Kraissmann, Oleo-mac Prosint. If you use a STIHL , how much oil should you fill per liter of gasoline? The ratio will be 25 ml of additive per liter of fuel. We must remember that there are oils for chains and motors. They are intended for different purposes and are not interchangeable. Using chain oil to prepare a fuel and lubricant mixture leads to tool failure.

Oil selection

Unlike four-stroke engines, STIHL 180 chainsaw oil is poured directly into the gas tank, after being mixed with gasoline. It is recommended to fill the chainsaw with the oil specified in the instructions for this model.

Under no circumstances should you use oil intended for low-speed engines (boats, scooters, etc.).

It can significantly shorten the life of the motor, and if traces of such a substance are detected in the cylinder-piston group, the tool will be considered void of warranty, i.e., it will not be subject to warranty repair or exchange.

Synthetic and mineral oils for STIHL chainsaws are sold in bottles or canisters of different capacities: from 100 ml to 5 liters. Mineral ones have a lower cost, while semi-synthetic and synthetic ones ensure complete combustion during engine operation, i.e., no soot and a minimum of toxic compounds in the exhaust.

In addition, synthetic oils retain their qualities over a much wider temperature range, and also contain special additives that are useful for engine operation: antioxidants, detergents, preservatives, etc.

You can choose motor oil for your tasks depending on the model of the saw and the frequency of its use: oil consumption during operation of the device is low, and given the shelf life of semi-synthetic and mineral lubricants, there is a risk of simply not having time to use even a liter bottle to the end.

So, if the expected volume of work is small, you can not buy a large canister, but limit yourself to a bottle. Only STIHL mineral lubricants do not have an expiration date.

Under the brand

For modern brands, for example, Husqvarna, Partner, Makita, Echo, Stihl

AI-92 gasoline is suitable. Now a colossal number of people are complaining about the early failure of chainsaws due to disgusting gasoline. That’s why some experts advise pouring AI-95 into such chainsaws. At the same time, a good AI-95 can “burn the piston,” and again, a certain number of people have found a compromise and combine AI-95 with AI-92. In general, everything depends on the properties of gasoline and in the end it’s up to you to decide.

For Russian instruments, Ural, Druzhba, it is recommended to take AI-80 gasoline. It is very important that fuel consumption is minimal.

How to dilute gasoline with trimmer oil

dilute gasoline for the trimmer in the correct proportion. An insufficient amount of oil can lead to poor lubrication of the trimmer elements, which contributes to rapid wear.

How to prepare a fuel mixture for STIHL tools

The correct ratio can be found in the trimmer instructions. Most often it is 1:25, 1:40, 1:50. To obtain these proportions, in 1 liter of gasoline you need to add 40 ml, 25 ml and 20 ml of oil, respectively.

It is unacceptable to dilute gasoline with lubricant directly in the fuel tank, and the proportion of oil and gasoline must be strictly observed. If you ignore this rule, the operation of the trimmer motor may be unstable, which is why it will quickly fail.

It is not recommended to use plastic bottles or canisters for this purpose. This is due to the fact that gasoline tends to dissolve plastic, which means that some of the plastic can get into the fuel tank, which can lead to carburetor failure. Although there are special plastic canisters marked “flame”.

Make a mixture of gasoline and oil as follows:

Pour 1 liter of gasoline into a container, add half the required portion of oil. Mix thoroughly, do this with extreme caution, away from sources of open flame.
Add the rest of the oil to the trimmer gasoline and mix thoroughly again. Now fuel can be poured into the trimmer's .

The mixture can be stored for no more than three months, so it is better to dilute gasoline in such an amount that it is enough for several uses.

Huter GGT-1500TX

Warranty and service official guarantee at the company service center

Description

The power of the Huter GGT-1500TX is 1.5 kW, which, along with the features of the cutting tool (line/knife), classifies it as a semi-professional class of similar devices. Therefore, the model can be used not only in dachas and country farms, but also in small farms. The GGT-1500TX will do an excellent job of both mowing grass and tidying up areas with small bushes. The trimmer weighs 6.78 kg, which makes transportation relatively simple, including in a regular passenger car.

Advantages of Huter GGT-1500TX

The presence of a two-stroke gasoline engine makes the device more autonomous compared to electric types of lawn mowers.
The engine is distinguished by sufficient power to solve problems and high reliability. It is also equipped with an anti-vibration system and is easy to put into operation.
The trimmer design includes a translucent fuel tank, which is convenient to fill with fuel and monitor its level.
There is a convenient and reliable trimmer control system located on the ergonomic handle.
The 1500TX boom has a split mechanism for easy and convenient transport.
The trimmer is easy to disassemble and assemble, but when assembled it is distinguished by the reliability of all components and fastenings.
Included with the model, the buyer receives a comfortable backpack-type belt, goggles to protect the eyes during operation, and a 40 TP disk.

Work conveniently and safely

Of course, the operator must follow all recommendations and safety requirements and follow the rules for operating the trimmer. However, in addition to this, the manufacturer has taken a number of measures regarding the design of the device to increase the level of safety when working with the lawn mower. These include in particular the presence of:

protective cover to prevent flying stones and debris from hitting the user,
trigger that blocks the gas so that the operator cannot accidentally pull the trigger and start rotation
cutting tool when the engine is running,
anti-vibration system to prevent the harmful effects of the vibrating elements of the trimmer on the hands and other parts of the operator’s body.

Features of operation of Huter GGT-1500TX

The assembled trimmer can now be prepared for upcoming work on the site. Preparation for operation begins with preparing the fuel mixture. At this stage, follow all the manufacturer’s recommendations regarding the brands and quality of fuel mixture components, and also accurately follow the procedure for preparing the fuel mixture, which, in reality, is not very difficult.

Since the Huter GGT-1500TX is equipped with a two-stroke air-cooled engine, to prepare the fuel mixture you need high-quality oil, specially produced for this type of engine. According to the classification, this oil is API TV/API TC, JASO FB/JASO FC. It is recommended to use oil produced by Huter itself under the label Huter 2T. The second component of the mixture must be high-quality gasoline with an octane number of at least 92. The use of oils produced for water-cooled engines in the fuel mixture is strictly prohibited. The fuel mixture is prepared in a ratio of 1:40 (1 - oil, 40 - gasoline) or according to the recommendations of the oil manufacturer.

For the process of preparing the mixture, use a special measuring container. The amount of mixture should be calculated for only one cycle, so that after completion of work there is no residual fuel mixture in the tank (it cannot be left in the tank until the next cycle of work). Also, never use the tank itself to prepare the mixture, and also do not perform operations with the components of the fuel mixture near the fire and do not smoke while preparing the fuel.

After the correctly composed fuel mixture is poured into the tank, you can proceed to the actual preparation of the trimmer for work. To do this, the user must first put on a backpack-type belt and fasten it securely, but comfortably. After this, using a special carabiner, the trimmer is attached to the belt and adjusted if necessary. For details on preparing the trimmer for use, see the User's Manual.

How to refill the trimmer

The prepared mixture of gasoline and oil can be stored for no more than 3 months (pure gasoline can be stored less). Dilute the fuel in an amount that is enough for several uses of the trimmer . In general, prepare:

gasoline and oil, which is suitable for two-stroke engines with an air cooling system;
metal canister and mixing container;
respirator;
gloves.

How to properly dilute gasoline with oil for a chainsaw or lawn mower

Adding oil to gasoline

Pour 1 liter of gasoline into a container of suitable volume and add 1/2 of the required amount of oil.
Stir carefully, being at a good distance from sources of open flame.
Add the remaining half of the oil to the fuel and mix everything again.

Trimmer refill process

General recommendations for refueling a trimmer with a two- or four-stroke engine:

Place the fuel tank so that the cap is on top, then fill in the required amount of fuel.
Do not overfill the fuel tank. This will lead to one of the problems: overflow into the intake pipe and fuel filter, ignition of the fuel or engine breakdown.
Try to pour the mixture so that it does not spill. To do this, you can use a watering can.
If you do spill fuel, wipe it up immediately. Dispose of cleaning material; do not accumulate it indoors - it is a fire hazard.
Start-up of the device should begin after the fuel canister has been removed to a distance of more than 10 m.
If there was a long break between uses of the mower, be sure to drain the remaining old fuel.

Features of refueling brush cutters

When the mixture is prepared and ready for use, it must be carefully poured into the fuel tank. Because gasoline is a toxic liquid, safety precautions must be observed when working with it. Work must be carried out in calm weather and away from outsiders. Also, to pour fuel into the tank, you must use the watering can or funnel with which you previously diluted the mixture. Otherwise, the mixture may spill, go unnoticed, and ignite when the engine heats up.

The fuel bank itself must be cleaned of external contaminants and only then unscrew its lid to fill with prepared fuel. After the fuel has been filled, the tank should not be left open, because insects or soil may get into it, resulting in the fuel filter becoming clogged. Fuel must be poured into the tank up to the marked mark or less, and then topped up later during operation.

During storage, the container must be tightly closed with a lid. Fuel must be stored in a cool room, in a place where the sun's rays do not reach it. It is worth keeping in mind that when the consistency is stored for a long time, the oil dilutes and loses its characteristics.

See below for more details.

Choosing oil for lawn mowers

For trimmer engines, it is necessary to choose oils marked “2T”, which are used for internal combustion engines with a volume of 50 to 200 cm 3 and are air-cooled. First of all, when buying oil, you should pay attention not to the price, but to the protective properties of the material, since small savings can subsequently become a real headache for the owner and, as a rule, large costs.

The main factor determining the quality of trimmer is the base number. It is this component that prevents oxidation of rubbing parts and slows down their destruction. During operation, the oil gradually loses its alkalinity and becomes oxidized. The optimal acidity level (Ph) should not be less than 8-9 units.

The viscosity of the brush cutter oil also has a great influence on the operation of a gasoline tool. This indicator determines the ability to operate the trimmer at different temperatures. For example, summer brands of lubricants thicken even with a slight drop in temperature. Due to the use of lawn mowers exclusively in the spring and autumn, oil with summer markings would be an excellent option.

The flash point for trimmer oil must be more than 225C, otherwise the oil will quickly burn out and the piston group will be subject to intense wear.

Storage recommendations

It is better to prepare the mixture in quantities that should be enough to complete one-time work. The problem is the irreversible deterioration of the working properties of the mixture during storage. It is recommended to use the finished composition over the next few days.

A mixture of gasoline and month-old oil impairs the traction capabilities of the engine. There is also the formation of resinous compounds in the fuel system and intense carbon formation in the combustion chamber, loss of mobility of the piston rings.

With minimal damage to quality, it is advisable to store gasoline and oil for no more than 2 weeks. At an ambient temperature of 25 degrees Celsius or more, this period is reduced to 8-10 days.
In order to save money, the expired mixture can be gradually consumed by mixing it into the fresh composition in an amount of no more than 10% of the total volume.

To avoid problems associated with fuel system failure, it is recommended to filter the prepared mixture through a non-fibre material such as suede, or a fine-mesh twill weave or metal mesh.

Fuel consumption

One of the most important questions that owners of sawing tools have, because everyone wants to know what to expect.

The volume of virtually all tanks is approximately 500 ml. If the power of the chainsaw is two kW, then the fuel consumption will be approximately 1.2 liters per hour of operation. To put it simply, such a tool will be able to work at maximum speed for half an hour without a break. If the chainsaw is not so powerful, then its tank volume will be much smaller. So the user can independently control fuel consumption.

Over time, the user will learn to create a service for his own tool without any help. The main task will be to maintain the economic unit in good working condition, using high-quality fuel mixtures. Follow safety rules when producing flammable water. This will help preserve the instrument and not harm yourself or the environment.

Measuring containers

To maintain the correct proportion of gasoline and oil, a calculation table applied to the saw body can be used. Branded containers of leading motor oil manufacturers are equipped with built-in measuring devices that provide accurate dosage of oil for different volumes of the fuel mixture.

Measuring utensils are included in the factory kit of many budget chainsaw models. In some cases, a medical syringe with a volume of 20 cm3 will help gasoline

Lubricants

More stringent criteria for selecting an oil component. The best option is a mineral or semi-synthetic motor oil recommended by the manufacturer, designed for use in high-speed two-stroke air-cooled internal combustion engines.

The advantage of mineral oils is their lower cost. Their more expensive semi-synthetic and synthetic analogues compare favorably with improved performance characteristics and compliance with environmental standards.

maintain performance properties over a wide range of operating temperatures;
do not form soot;
contain detergents, antioxidants, preservatives and other additives useful for the operation of the power unit.

Varieties

The oil that is poured into the engine may differ in the method of production. According to this criterion it happens:

This type of mineral is obtained by processing petroleum products;
Synthetically it is obtained by processing or synthesis of gas;
Semi-synthetic, this type has more advanced characteristics due to the introduction of synthetic-based components into it.

Gasoline cutter oil refers to compositions intended for use in air-cooled engines that have a combustion chamber of 50-200 cubic centimeters. In addition, any two-stroke oil may differ from its analogues by additives that give it certain additional characteristics. They come in the following types.

Antioxidant. The main task of the oil will be to reduce wear on parts during operation of the device.
Antioxidant. They prevent oxidation from occurring and make it possible to maintain oil performance for a long time.
Anti-corrosion. Their task. Prevent corrosion on engine parts.
Friction modifiers. These additives can significantly reduce the coefficient of friction.

Recently, when buying oil for dilution with gasoline, users are very often faced with the fact that special letter abbreviations are used for cans. These designations are made within the framework of the API classification. Let's consider what types of oils exist in accordance with it.

And applies to air-cooled brushes whose engine capacity is not more than fifty cubic centimeters. It can be used not only for mowers, but also for mopeds, lawn mowers and other types of equipment. For a gasoline trimmer, this is the optimal solution.

TV is used to refuel chainsaws , scooters, mopeds or motorcycles with an engine capacity of less than two hundred cubic centimeters. Can also be used to refill gasoline trimmers.

TC is suitable for thinning and filling gasoline into snowmobiles, motorcycles and other types of equipment.

TD is designed for refueling boats , yachts and hoverboards.

But besides this classification, other letter designations such as FA-FD are often found. It should be said that API. American standard used in Europe. But there is a discrepancy between European and American smoke emission regulations. For this reason, additional letter designations should also be taken into account.

FA can be used in countries where minimum exhaust emissions are required by law. Subtle smoke may be emitted when using oils of this grade.
FB can be used in countries where restrictions on smoke and gas emissions are much stricter. In this case, there is practically no smoke emitted.
The FC is a transparent smoke that the human eye cannot see.
F.D. This is a special category of oils for two-stroke engines; they do not create smoke at all. They have enhanced chemical properties. Typically this oil is used to mix with gasoline and then refuel boats and yachts.

In addition, oils come in two more categories:

Selfmix;
Premix.

In the first case, this will mean that you need to perform self-mixing, which does not require shaking, and in the second case, you will need to do this as well.

Self-selection criteria

A large assortment allows you to choose an oil that fully corresponds to the class and characteristics of the chainsaw, and the conditions of its subsequent operation.

For budget models, you can use oils of the Standard category; for professional chainsaws, consumable lubricants of the Super and Ultra categories are recommended.
To prepare a complete fuel mixture for a chainsaw, it is advisable to use branded oils or their branded analogues recommended in the operating instructions. In particular, STIHL and Husqvarna motor oils of the same type in composition and application are completely interchangeable.

Experts recommend that owners of chainsaws exclude from attention motor oils intended for two-stroke engines of mopeds, boat engines and other mechanized household equipment.

The power units of this equipment operate in more comfortable conditions, which makes the requirements for their performance characteristics less stringent.

Purpose

Engine oil. It is a special mixture of solvents and friction-reducing additives. They form a certain viscosity and prevent the composition from thickening when the temperature drops. Typically, oils are specially dyed in different colors: green, red or blue. This prevents them from being confused.

Keep in mind that they may differ in composition, so gasoline trimmer oil will be labeled for horticulture. In addition, it may also differ in marking: 2T or 4T. 1st. This is a two-stroke oil that is poured into the corresponding engine. And the second one is intended for pouring into the crankcase.

Oil dosage in Chinese version

Many Chinese-made chainsaws are simplified copies of popular European-designed models. The lack of special materials and proprietary technologies contributes to the preservation of the outdated proportion of gasoline and oil in the ratio of 25:1.

The doubling of engine oil consumption is compensated by its lower cost. According to the developers, original components are introduced into Chinese oils that help increase the wear resistance of power units and actually extend their designated service life.

According to independent experts, the best brands of Chinese motor lubricants correspond in quality to analogues from European manufacturers in the mid-price range. This is the level of branded motor oils of the Standard group and partially Super.

Benefits of branded oils

STIHL , Husqvarna and Makita have the highest ratings

Only in certain parameters the branded assortment is inferior to domestic motor oils of the Lukoil brand.

The list of advantages of branded motor oils:

economical consumption;
stability of performance characteristics under difficult operating conditions and during long-term storage;
minimal amount of toxic compounds in exhaust gases;
almost complete absence of soot.

HOW TO CORRECTLY DILUTE GASOLINE WITH OIL 1:50

According to the American classification, oils of the API-TB category can be used for work in household and professional models. The Japanese equivalent is JASO-FB and JASO FD. Preparation of a flammable mixture using oil for 4-stroke engines is strictly prohibited.

Red, green or any other color of the oil determines whether the product belongs to the range of a particular manufacturer, and therefore is not taken into account when determining the characteristics of the material. You should be extremely careful when choosing motor oil of unknown composition and origin.

Until additional information about quality and operational parameters is obtained, it is better to temporarily abandon the use of such material.

It is allowed to mix motor oils of the same type in composition and purpose produced by brands known for the quality of their range. Under no circumstances is it permitted to mix mineral and synthetic oils.

Working proportions of the fuel mixture

The standard ratio of gasoline and oil in the fuel mixture for chainsaw carburetor engines of different models is 40:1 and 50:1. This proportion ensures complete lubrication of the rubbing parts of the crank mechanism and piston group, and also does not interfere with the complete combustion of the gasoline-air mixture.

Taking into account external factors, the fuel mixture can be adjusted to increase the amount of oil. This need arises at the stage of running in a new tool, as well as at high air temperatures. In this case, the standard dosage of oil is increased by 20%.

In practice, an increase in the percentage of oil in the fuel mixture is used if its characteristics do not fully meet the stated requirements. How much oil per liter of gasoline is needed in each specific case is determined by the sawyer himself.

The ratio of gasoline and oil for a chainsaw

Household and professional chainsaws are powered by two-stroke internal combustion engines running on a dosed mixture of gasoline and motor oil adapted to difficult operating conditions. The correct proportions of oil and gasoline for a chainsaw are one of the important conditions for stable traction characteristics of the engine and low-cost development of its designated resource.

The need to obtain sufficiently high power from a small-cc power unit forces chainsaw engines to be operated at high-speed modes, so increased demands are placed on the quality of both components of the fuel mixture.

Good to know

Fuel must be stored for three refuelings. After all, storing a huge amount of fuel can have a bad effect on the operation of the chainsaw. The mixture can behave differently, because it will be influenced by a huge number of reasons. As a result, your household unit may suffer serious damage, which will entail financial costs.

From time to time, even the container can affect the quality of the water. Plastic and glass react with gasoline, which can create a risk of unexpected fire.

The finished liquid cannot be stored for more than a month, because the oxidation process occurs. After working with a chainsaw, it is necessary to use up the remaining fuel, turn off the engine and remove the remaining fuel mixture
