High-quality filling of a chainsaw with fuels and lubricants determines its traction characteristics and service life. Information about what kind of gasoline to pour into the chainsaw is available in the attached instructions, but there is practically no information about the nuances of choosing consumables in the description.
The design feature of power units of chainsaw equipment is, first of all:
- ability to work for a long time at high-speed operating modes;
- compact dimensions;
- small displacement and high compression ratio.
The given characteristics impose special requirements on the selection and quality of fuels and lubricants.
The operational characteristics of the saw, in particular, gasoline consumption per hour, engine thrust and low-cost development of the tool's service life between overhauls, are largely determined by competent adjustment of the carburetor and the correct selection of fuel mixture components.
What happens if you don't dilute gasoline with oil?
For chainsaws with two-stroke engines, a mixture of oil and gasoline is used - this filling allows you to ultimately obtain more engine power without taking up a large volume, without creating a bulky structure. A two-stroke engine cannot run on pure gasoline, since as a result of the combustion of gasoline additives, rust will quickly appear on spark plug electrodes and nozzles, and fuel consumption will be very high.
Refueling a chainsaw
Recommended sequence
In accordance with the standard technology for preparing the fuel mixture, the calculated amount of oil is poured into a tank half filled.
The mixture is thoroughly mixed with the plug closed, after which the remaining gasoline is poured. This sequence contributes to the homogeneity of the resulting composition.
It is advisable to prepare fuel for a chainsaw in quantities sufficient to perform one-time work. The finished composition can be stored at a standard temperature of 20°C for no more than one month. At higher temperatures, the shelf life is reduced to 2 weeks.
An expired mixture initiates the formation of resinous compounds, which contribute to clogging of the jets, the formation of carbon deposits and limiting the mobility of the piston rings. In order to save money, the overexposed composition can be consumed by adding up to 15-20% of the total volume to the fresh mixture.
Suitable gasoline brands and their classifications
Modern manufacturers of chainsaws recommend using gasoline with an octane rating of 90 or more for all tools. For example, AI-92 gasoline. There are also references to AI-95 gasoline, but it is less popular because it is more expensive and contains a larger amount of methyl tert-butyl ether, an additive that reduces the risk of fuel detonation.
AI-92 gasoline consists of isooctane and n-heptane (92% and 8%, respectively). These two components balance each other in octane numbers, which means they are best suited for filling a chainsaw tank.
It is not advisable to use cheap gasoline or fuel that has been sitting in a canister for more than two months. Mixing gasoline with low-quality, cheap oil or waste oil is also unacceptable.

Chainsaw device
Each chainsaw has different technical specifications and can perform different jobs.
Powerful saws are suitable for felling centuries-old trees; small chainsaws are more suitable for performing various tasks in the household:
- Cutting tree branches
- Firewood harvesting
Expert opinion
Kuznetsov Vasily Stepanovich
The design of the chainsaw is simple, there is not even a gearbox, it operates a two-stroke power plant, it contains one gasoline cylinder.
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.
Chainsaw owners are primarily interested in fuel consumption. The volume of the fuel container is usually 550 ml. Let's say the device's power is only two kilowatts. In one hour of operation, such a unit will consume 1.25 liters. If the tool operates in afterburner mode, then the fuel may be enough for 20-30 minutes of continuous operation.
Suitable oil brands and their classifications
In order to dilute the fuel mixture for a two-stroke engine, the following types of motor oils are used: synthetic, semi-synthetic. It is not advisable to use mineral oils because they tend to harden at low temperatures and are more expensive. Recommended type of oil to add to gasoline to prepare the mixture: oil for two-stroke air-cooled engines.
Modern manufacturers of fuels and lubricants label oils by type: synthetic, mineral, semi-synthetic, so it will be difficult to make a mistake with the choice. Please note that European oil quality standards have been lowered, however the Swedish brand Husqvarna has kept the old standard as the benchmark. This is why the dilution ratio of Husqvarna oil with gasoline is lower than that of other brands of oil.

Recommendations for choosing gasoline
According to current standards, the best gasoline for a chainsaw should be unleaded, high-octane, and fairly fresh. A high degree of purification from foreign impurities is welcome.
- Filling the fuel system with fuel that has been stored for more than six months has a negative effect on the traction characteristics of the internal combustion engine, promotes carbon formation and the occurrence of detonation phenomena.
- It is advisable for beginners and experienced users to exclude from their attention low-octane gasoline for chainsaws, as well as cheap motor oils of unknown origin. The use of leaded fuel is not prohibited, but in order to extend the life of the saw, it is best to abandon its use at the selection stage.
Practice shows that saving on the quality and cost of consumables negatively affects the performance characteristics of chainsaw equipment and the duration of its full operation.
Mixing principle and proportions
Oil from all manufacturers, except Husqvarna, must be diluted in a ratio of 1:33, that is, the output will be a 3% mixture with the following composition: 30 grams of oil are required per liter of gasoline.
Husqvarna oil is mixed in a ratio of 1:50, the resulting mixture is 2%, which contains 20 grams of oil per liter of gasoline.
The tank volume of a chainsaw differs depending on the engine power and its capacity (in cc). The average capacity of chainsaw gas tanks is from 300 to 600 ml or more, oil tanks - from 200 to 400 ml. and more. The more horsepower the saw produces, the more gasoline is placed in the gas tank.
The average fuel consumption per hour for a chainsaw ranges from 257 to 380 g/kW/hour. The consumption of the gasoline-oil mixture depends on indicators such as the degree of load on the chainsaw, operating time without shutting down, the condition of the saw chain and bar, the smooth operation of the carburetor, as well as the model of the chainsaw.
For example, the latest generation of saws consume fuel more efficiently than older models.
Proportions of oil and gasoline for a chainsaw - preparing a mixture for refueling a two-stroke engine
Why doesn't oil flow to the chainsaw chain?
If oil does not flow to the chainsaw chain at all, it means either the oil pump drive itself has failed, or there are problems with air leaks.
- Oil pump failure. If, when the oil pump plunger adjustment screw is unscrewed, oil is still not supplied to the chainsaw chain, then the drive, which is a plastic ring with grooves, has broken down. Over time, the grooves can wear out and the drive will fail, after which it will simply have to be replaced.
- The hose that supplies pressurized oil to the chain has collapsed or worn out. You need to re-attach it to the fitting or replace it.
- The grooves through which oil is supplied to the chainsaw chain are clogged - this is the most common occurrence. They need to be cleaned, after which the supply will resume.
How long can the diluted prepared mixture be stored?
The standard shelf life of the prepared oil-gasoline mixture is 1 month. Chainsaw manufacturers recommend in their operating instructions not to prepare large quantities of fuel mixture. The best option is to prepare the mixture for operation and full production, and then refill with fuel if necessary.
It is generally undesirable to store the mixture in the fuel tank of a chainsaw for longer than two to three weeks. When not using the tool, it is recommended to drain the fuel and dry the tank.
Fuel for a chainsaw - prepare the mixture:
Features of preparing the mixture
For safety reasons, it is recommended to prepare the fuel mixture in a metal canister that is not subject to the formation of static electricity.
- The recommended proportions of gasoline and oil are individual for each model. In most options, this is a ratio of 50:1 and 40:1. Much less common are chainsaws that run on a gasoline-oil mixture in a ratio of 25:1.
- According to manufacturers of branded chainsaw equipment, their products do not require running-in. However, during the first hours of operation, experts advise operating a new chainsaw on a fuel mixture with a high oil content and, if possible, in a gentle mode.
Containers with built-in dispensers are convenient for preparing the working mixture. The selectivity of fuel filters at gas stations, in some cases, leaves much to be desired, so it is recommended to filter gasoline through suede or non-fiber material.
Following these recommendations will eliminate spontaneous equipment failures associated with malfunction of the carburetor.
The specific characteristics of mineral or organic chain oil are aimed at lubrication and cooling of saw accessories, and therefore are not suitable for preparing a fuel mixture.
Reviews from chainsaw owners about refilling the tool
Gena, Ulyanovsk:
“I want to share an important observation. It will be useful for owners of chainsaws originally from the USSR - the Urals or Druzhba. Previously, it was believed that such saws needed 50 grams of oil per liter of gasoline, and even 60 grams during break-in. Nowadays oils are of higher quality, so you can safely pour 20 grams per liter! This observation made it much easier for me to operate the chainsaw and eliminated excess oil. I recommend that everyone who has such “old saws” try this proportion for their tools.”
Can You Fill a Chainsaw with 95 Gasoline?
What kind of gasoline should be poured into a chainsaw?
Hello! I am glad to see you again, dear readers and subscribers of Andrey Noak’s Blog. What kind of gasoline to put in a chainsaw and others. Anyone who has a chainsaw already knows exactly what kind of gasoline and how to fill it. But for those who just want to purchase such a unit for themselves, the article will seem interesting.
A chainsaw is one of the most comfortable and versatile household appliances. Before use, it is necessary to prepare the fuel mixture. But in order for the unit to work correctly, you must follow all the manufacturer’s recommendations. Each model is individual, so what kind of gasoline should you put in your chainsaw?

Under the brand
For modern brands, for example, Husqvarna, Partner, Makita, Echo, Shtil, AI-92 gasoline is suitable. Today, a huge number of people complain about premature failure of chainsaws due to bad gasoline. What gasoline to pour into and how to dilute gasoline for gasoline for a chainsaw. Therefore, some experts recommend pouring AI-95 into such chainsaws. At the same time, good AI-95 can “burn the piston,” and again, a number of people have found a compromise and mix AI-95 with AI-92. In general, it all depends on the quality of gasoline and ultimately it’s up to you to decide.
For domestic instruments, Ural, Druzhba, it is recommended to take AI-80 gasoline. It is very important that fuel consumption is minimal.
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 pure gasoline into the chainsaw is strictly prohibited! The manufacturer indicates the proportions, quantities and some brands in the operating instructions.

Important points during the cooking process:
- Domestic chainsaws work with oil M8-V, M-12TPU, M8-V, TP, MGD-14M. Since chainsaws use a two-stroke engine, where it is structurally impossible to install an oil pump, pure gasoline cannot be poured into the chainsaw! In some cases, foreign options can be used;
- Proportions: 2.5 liters of FI-80 gasoline per 100 grams of oil;
- Foreign models are characterized by minimal fuel consumption. What kind of gasoline can you use in a Calm chainsaw? They work on foreign oils, and their proportions are 1:40 or 1:50.
Fuel mixture
To properly prepare fuel, you will need a list of additional tools:
- Plastic or metal container for diluting the substance;
- Measuring bottle for gasoline;
- Dispenser;
- Syringe;
- Watering can for filling the tank of a chainsaw.
Some manufacturers, such as Stihl, immediately make measuring containers for more convenient measurement of the fuel mixture.
Different manufacturers produce oils in different shades. The manufacturer HP produces a red liquid. So what kind of gasoline should you put in your chainsaw? AI-95 with AI-92. Into gasoline into a chainsaw. Green oil is in the premium “synthetic” segment. For a Husqvarna chainsaw you need to take the appropriate brand of oil.

Good to know
Fuel must be prepared for 3 refills. After all, storing a large amount of fuel can negatively affect the operation of the chainsaw. The mixture can behave differently, because it will be influenced by many factors. Is it possible to use 92 gasoline instead of 95 in a chainsaw? As a result, your household unit may suffer serious damage, which will entail financial costs.
Sometimes even the container can affect the quality of the liquid. You can pour the finished oil into it and use the chainsaw for longer. You can buy gasoline to pour into a chainsaw, then it will be optimal to use the fuel. Plastic and glass react with gasoline, creating a flash fire hazard.
It is important to remember that if the chainsaw breaks down due to poor-quality or incorrect mixture, it will not be possible to repair the unit under warranty.
The finished liquid cannot be stored for more than a month, because the oxidation process occurs. After working with a chainsaw, you need to use up the remaining fuel, turn off the engine and remove the remaining fuel mixture .
Fuel consumption
One of the most important questions that arises among owners of saw tools, because everyone wants to know what to expect.
The volume of almost all tanks is approximately 500 ml. What kind of gasoline should be poured into a chainsaw. Green oil is also available for sale. If the power of the chainsaw is 2 kW, then the consumption of the fuel mixture 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 smaller.

Over time, the user will learn to service his tool without any help. Is it possible to put 95 gasoline into a chainsaw? The main task will be to maintain the economic unit in good working condition, using high-quality fuel mixtures. Follow safety rules when preparing flammable liquids. This will help preserve the instrument and not harm yourself and the environment.
Helpful Tips:
- Sometimes it's better to add a little oil than to regret it. If you give a little more oil than indicated in the instructions, then nothing bad will happen. The formation of carbon deposits is possible in cases of a large amount of oil and if the specified 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 quality;
- 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 intended 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, at least, the instructions on the oil packaging. This will help 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 high quality, because tool failure can cost much more (about 80% of the cost of a chainsaw) than the money saved on the fuel mixture.

What errors and consequences may occur?
The main mistake that inexperienced chainsaw owners make is trying to save money on expensive oil. Often, users try to lower the oils a little, believing that this will not cause any serious problems. However, the consequences of such savings can be very disastrous - a lack of lubrication will cause overheating of the parts, which will negatively affect the overall performance of the tool.
The most serious consequences of such actions include jamming of the piston in the cylinder, which will require major repairs. Sometimes it costs more than buying a new tool. Therefore, you should not save on oil; only strict adherence to the manufacturer’s instructions will help you get maximum performance and long service life from your chainsaw.
The consequences of excess oil can be no less harmful. When using such a fuel mixture, carbon deposits will form in the cylinder, which will cause breakdowns and the need for serious repairs.
A properly prepared fuel-oil mixture for a chainsaw is the most important condition for high-quality and productive work. You should not assume that a slight change in proportions is not scary and will not cause serious problems. Only careful compliance with the manufacturer’s requirements and accuracy in the composition of the mixture guarantees the user full compliance of the operational parameters of the tool with the declared indicators.
Why is gasoline mixed with oil to refuel chainsaws?
It is necessary to dilute gasoline with oil to avoid failure of the internal combustion engine. The reason for this is the design features of the lubrication system of two-stroke engines. The design of such engines does not have a chamber for filling engine oil, and if fuel is added without lubricant, the crankshaft, piston, bearings and connecting rods will not receive lubrication. This will significantly reduce the service life of all listed parts, so filling with clean fuel is prohibited.
Gasoline and chainsaw oil must be poured in appropriate proportions, which makes it possible to effectively lubricate the rubbing parts. A lack of lubricant or its excess will lead to negative consequences in the form of carbon deposits. In order for the tool to work properly, from the first day of operation of the tool it is necessary to fill it not only with high-quality materials, but also to maintain the correct proportions.
In order for the engine to work properly, the main thing is to fill it with clean fuel without contaminants.
Alternative fuel option
To refuel household and professional chainsaws, it is recommended to use auto gasoline type AI-92 that does not contain alcohol components and additional additives.
The question of whether possible to pour 95 gasoline into a chainsaw remains controversial to this day. At a theoretical level, the anti-knock characteristics of AI-95 gasoline are higher than those of standard AI-92 fuel, but in practice it is better to give preference to the second option.
The problem is that in order to increase the anti-knock properties, manufacturers and distributors introduce additives into the composition of 95-grade gasoline, the quality and effectiveness of which raises reasonable doubts among professionals.
Such fuel does not one hundred percent meet the required characteristics and does not have adequate stability during long-term storage. After 3-4 months of aging, its performance characteristics deteriorate by 25-30%.
Risks of using fuel and oil substitutes
The design features of internal combustion engines of Russian and imported chainsaws exclude the use of more affordable biofuel and gas-condensate gasoline substitutes. The operating properties of such fuel are currently far from perfect.
In the total sales of motor oils, counterfeit lubricants, according to various sources, range from 8 to 15%. Only an experienced specialist can distinguish unusual products from counterfeits.
To eliminate the possible risks of premature failure of the saw, it is recommended to obtain consumables from branded retail outlets and representative offices of dealer companies.

Despite all the external similarity, it is forbidden to use oil for two-stroke internal combustion engines of mopeds and light bikes to produce a working fuel mixture. The use of non-recommended lubricants may result in service providers refusing warranty obligations.

How to mix the fuel mixture correctly?
The mixing process is quite simple - you need to measure a certain amount of oil and pour it into the corresponding volume of gasoline. It is necessary to prepare a clean container in which mixing will be carried out. Plastic canisters are usually used and are quite suitable for this purpose. However, some types have a serious drawback - they accumulate static electricity, which can lead to the formation of a spark and ignition of the fuel mixture.
The best option is to use a special canister with two necks into which gasoline and oil are poured, but they are quite expensive. To accurately dose the oil, many people use medical syringes with markings. The more carefully the amount of mixture is measured, the longer the service life and the higher the quality of the tool.
Attention! It is prohibited to mix gasoline and oil directly in the gas tank of the tool. Learn more about how to turn on a chainsaw.

Proportions for Swedish Husqvarna chainsaws
What exact rate of lubricant is required to prepare the combustible mixture necessary for the normal operation of a two-stroke gasoline internal combustion engine? Buyers will learn about this from the instructions supplied with the product. But documentation is often lost among papers. In this regard, it would be useful to remember that manufacturers use transmission lubricant for mixing with gasoline. The Swedish company is known on all continents of the planet for supplying reliable goods to trade markets. Oil for Husqvarna chainsaws is strictly recommended by the manufacturer.
Depending on how much power is required to be obtained from the units, select the appropriate component dilution:
One liter of fuel is diluted with 40 to 50 parts of oil. These are the ideal proportions of gasoline and oil.
Along the way, we inform you that only unleaded gasoline of the AI-92 or AI-95 brands is used. A leaded combustible product is considered a poor choice for internal combustion engines, as it shortens the engine's service life.
Structure company of Husqvarna HP
The brand structure of the Swedish manufacturer Husqvarna HP includes a company that produces mechanized hand tools and lubricants for them, and effective chemical additives.
Chainsaw manufacturer Partner has developed an original ratio of fuel and oil for two-stroke power plants:
The mixing ratio of the fuel consistency is derived by the standard formula 1:50. This is a constant. That is, 20 milliliters per 1 liter of AI-92.
There are moments of non-compliance with the standard approach to dilution with a lubricant product of the company’s own production. This is when the internal combustion engine goes through the break-in stage. The fuel mixture allowed for the engine is 1:40.
Criteria for choosing engine oil
To make your own flammable mixture, use the heat-resistant branded motor oil recommended by the manufacturer in measured quantities.
- The specificity of this lubricant is its use in high-speed air-cooled internal combustion engines, which are equipped with household and professional-class chainsaws.
- Depending on the season, motor oil of different densities is used to make a flammable mixture, maintaining performance characteristics within the temperature range indicated on the label.
- For implementation, branded oils are recommended that provide complete lubrication of the piston group and connecting rod and crank mechanism in all operating modes of the unit.
- Branded products differ in color. Namely, Shtilevsky mineral oils are reddish, while synthetic oils are colored greenish. Husqvarna branded motor oils are blue or greenish.
Even taking into account the lowest price of mineral oils, it is recommended to use the advantages of synthetic analogues to produce a high-quality fuel mixture.
Shelf life of the finished fuel mixture
The finished fuel mixture deteriorates faster than gasoline, so the necessary components should be mixed immediately before starting work. It is possible to store the finished mixture for 10 days, but you should be prepared for the fact that its quality level will decrease.
Fuel should be stored in a tightly closed, opaque container: any plastic or metal canisters designed for flammable materials will do. You can also use oil containers or dark glass containers.
How long does fuel last?
During long-term storage, gasoline evaporates (regardless of the brand), sediment forms at the bottom, it loses its properties, in other words, it deteriorates. It is worth knowing that it is not so much the gasoline itself that ignites, but its vapor. Therefore, if there has been a can of gasoline in the garage since last year, then think, is it worth it? Better leave it to light the fire for the barbecue.
Using “stale” gasoline for a chainsaw entails many problems:
- difficult starting;
- reduction in maximum power;
- increased wear of engine parts.
It is worth remembering that the prepared fuel mixture (gasoline and oil) can be stored for no more than a month; after this time it should be disposed of.
Using an old mixture increases wear on chainsaw engine parts - don’t forget about it! All this will soon lead to expensive repairs of the chainsaw, at best the carburetor, at worst the engine.
About burning gasoline
I would like to explain a little how gasoline of different octane numbers burns; we need this to understand the power and small savings. Yes, I would like to point out right away that it is not the gasoline itself that burns in the engine, but a mixture of gasoline vapor and air. The following is a mixture of a certain octane and air:
- 76 (80) gasoline - burns quickly and does not last long, I would even say explosively. It flared up quickly and went out quickly.
- 92nd - ignition is not so explosive, but gradual, that is, the flame spreads much “softer”, and combustion also takes a little longer.
- 95-98 - it becomes clear that the higher the octane, the softer the spread of flame in gasoline (if I can say so), more evenly or something. YES, this fuel burns longer.
Therefore, performance on high-octane types seems softer and the engine runs quieter. IT DOESN'T APPEAR, in fact it is so.
Refueling instructions
Having combined the two main components in the required dosage and stirred them thoroughly, proceed to the refueling process.
Place the tool on a flat, clean surface. Before unscrewing the gas tank cap, clean it of sawdust and other contaminants. Make sure that the tank neck is pointing upward.
Place a small watering can in it, and then start pouring fuel. Since the tank volume is small, control the filling process. There is no need to fill the container to the brim, as when you close the lid, some of the mixture will splash out.
After filling the fuel, add chain oil to a separate tank. Its consumption is approximately equal to fuel consumption, so it is necessary to refuel both tanks at the same time.
After refueling, start the engine, moving a few meters from the work site.
