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.
Analogs
Worthy competition for this model comes from domestic class household chainsaws of the same type in terms of power and application from leading European and Asian manufacturers. The Russian market offers models identical in basic parameters - Husqvarna 236 X-TORQ, Oleo-Mac GS 35C-14, Hyundai X 380 and MTD GCS 3800/35.

Fuel selection
Which fuel to choose for a chainsaw is not an idle question; the success of the unit’s operation directly depends on it. According to existing canons, good gasoline for a chainsaw is considered to be not leaded, but high-octane from a trusted manufacturer. The cleaner the fuel, the better. If gasoline has been stored in a canister for a year and a half, this will negatively affect the operation of the device, so the substance should be prepared just before starting work.
It is recommended not to use low-octane fuel and to completely exclude inexpensive oils of dubious quality. You should not use leaded fuel; it significantly reduces the life of the power plant.
It is important to ensure that the fuel does not contain alcohol or any additives that could interfere with the functioning of the power plant. Experts are still debating whether 95 or 92 is better. The first has more stable detonation indicators, but most often they still use 92. The reason is simple: questions often arise about the 95, it contains a large number of different additives that have a bad effect on the operation of the saw engine. Microdetonation occurs (piston impulse in the opposite direction), which occurs at almost every revolution of the crankshaft. If the octane number is even higher (98), then the micro-shocks will become even more intense.
The consequences of incorrect gasoline on the quality of operation of the unit can only be negative:
- The mechanism will be difficult to start.
- The power will be minimal.
- Parts will wear out more intensively.
Expert opinion
Kuznetsov Vasily Stepanovich
You should not fill your chainsaw with gasoline from the bottom of the canister. The wire channels of the carburetor have small diameters; if they become clogged, this will cause the chainsaw to break down. All fuels should be carefully filtered before use. For domestic saws "Ural", "Druzhba" the fuel grade "80" is suitable.
Summing up
In order for your chainsaw to serve for many, many years, never fill it with old gasoline, and you don’t need to use grade ninety-five, much less ninety-eight gasoline, only 92, to make the fuel mixture. Also, don’t forget about the purity of gasoline—no dressing up!
I hope now you are not wondering which gasoline is suitable for a chainsaw and which is not so good.

How much oil should be added to gasoline?
Types of oils used for dilution in gasoline
Chainsaws do not have oil pumps, so the combustible mixture alone cannot be used. You should carefully read the instructions supplied by the manufacturer with each product. There is a lot of information on the Internet, finding it is not difficult.
If there is no lubrication, the saw will fail in a short time. It is recommended to do preventive maintenance of the unit, fill with properly diluted fuel, in this case the tool will function for many years.
You should carefully read the recommendations from ), they always describe in detail what composition is required for the power plant. There is no point in saving on oil, the benefit is small, and the engine life can be significantly reduced. Repairing an instrument is expensive, up to 85% of its cost.
If we take, for example, a Husqvarna chainsaw, then unleaded gasoline with the first additive of grade 92 is suitable. If the composition has a greenish color, then this indicates that the product is “Premium”. AI-92 is the optimal product that can be suitable for such a device. On average, professionals advise adding from twenty to 50 ml of machine oil per liter. If the power of the unit is one and a half kilowatts, then only 25-27 ml of oil will be required.
Expert opinion
Kuznetsov Vasily Stepanovich
If the tool is more powerful, then about 30 ml of oil is required, and in some cases even more.
How to dilute engine oil and gasoline, in what proportions? This question arises for all users. First you need to stock up on containers:
- Measuring liter bottle
- Dispenser and syringe
- A watering can that will allow you to pour the substance into the tank
The process of mixing oil and gasoline is technologically simple. It is important to follow safety precautions so that static electricity does not accumulate and not a drop of water gets into the fuel.
Types of oils used for dilution in gasoline
What proportions should be made? Engines are mostly two-stroke, so the mixture is usually 1:50. Russian-made chainsaws operate with products of the following brands:
- M8-B
- M-12TPU
- TP
- MGD-14M
For foreign analogues, it is permissible to use two liters of gasoline per 80 grams of oil. Foreign saws are characterized by economical fuel consumption; the proportions of oil in them vary from 40 to 49 parts.
Oil shades can vary significantly; this should be taken into account during operation. For example, it produces reddish-colored machine oil. If the composition has a greenish (sometimes blue) tint, then this is a sure sign that the product is premium synthetic. The quality of such compositions is high, and the cost is also quite high.
What happens if you don’t take the recommendations into account?
An inexperienced person does not know how to dilute gasoline with oil, how to choose the right fuel, what proportion of gasoline to use, and many other nuances. Often such ignorance leads to a large number of problems in the operation of equipment:
- increase in fuel consumption;
- defects of the unit and its components;
- the appearance of extraneous noise;
- strong toxic exhaust, etc.
Therefore, experts recommend following advice related to all aspects of equipment operation, from how to choose the right fuel to how to dilute gasoline for a chainsaw.
Video instruction: How to properly dilute gasoline with oil for a chainsaw
The main task: correctly calculate the proportions; if there is too much oil, carbon deposits will appear on the piston. Excess gasoline provokes the appearance of scuffing on the piston. The performance characteristics of the models vary quite significantly, which is why it is important to read the “User Instructions”.
Mineral oils are inexpensive, so they are most often used. Synthetic oils must be filled in if there are significant temperature fluctuations; they do not generate carbon deposits and have additives that are useful for dynamic components.
The product is considered the highest quality, with Lukoil machine oil in second place.
Advantages of these oils:
- Insignificant consumption.
- Maintaining quality.
- The ability to maintain technological qualities for a long time.
- Can work in extreme conditions.
- No toxins.
- Minimum amount of soot.
Many professional tools use lubricant made using API-TB technology (USA). Products that are produced using the JASO-FB method (Japan) are also popular.
It is forbidden to use a substance if the packaging indicates that it is intended for four-stroke engines. If the oil manufacturer is unknown, then it is better not to use it.
What kind of gasoline do you use for your chainsaw?
9592
It is acceptable to mix oils from different branded manufacturers with similar characteristics. Mineral and synthetic oils are incompatible with each other. The best oil for household chainsaws is considered “Standard”; for professional equipment, “Ultra” technical fluid is optimal.
Some oils can successfully replace each other. For example, substances produced by Husqvarna and Shtil. Lubricant for engines of scooters or motor boats is not suitable for chainsaws; the quality of the oil in them is low. If the proportions of oil and gasoline are not maintained, the tool will quickly fail due to the excessive formation of carbon deposits.
Expert opinion
Kuznetsov Vasily Stepanovich
If the power of the tool is up to 1500 watts, then 100 grams of engine oil are added to 4 liters of fuel. If the power is greater, then a proportion of 1:50 is used, that is, 100 ml of product is required for five liters. Manufacturers' recommendations vary significantly; it is recommended that you familiarize yourself with such information first.
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. 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. They work on foreign oils, and their proportions are 1:40 or 1:50.
Advantages and disadvantages of oil
Any high-quality machine 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 Khurstavna chainsaw, but only gear oil is required for the Shtil chainsaw. 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.
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:
- Air temperature.
- Humidity.
- Solar radiation intensity.
- Pressure.
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.
The specificity of the lubricant is that it is optimally suited for high-speed engines that are air-cooled. It is these power plants that are equipped with chainsaws. Oils of mineral origin have a reddish tint, while “synthetics” have a greenish tint.
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:
- 50:1.
- 40:1.
Expert opinion
Kuznetsov Vasily Stepanovich
There are almost no chainsaws on the market that operate on a mixture in a ratio of 25:1. After pouring the new mixture, the tool should run for some time at idle speed.
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.
How is mixing done?
In order not to spend a lot of time on preparatory operations and not to store a large amount of fuel mixture, it is usually prepared in quantities equivalent to 3-4 refuelings of a chainsaw. Mixing can be done correctly only if you have measuring containers.
In general, you need to take a clean and dry bottle or canister and pour the required amount of gasoline into it using a funnel. After this, dilute the gasoline by adding oil. It is convenient to measure it using a syringe of the required volume without a needle. Close the container with a lid and achieve uniform mixing with oscillating movements. The oils used are painted in bright colors, so the finished mixture will have a tint by which it can be easily distinguished from pure gasoline and can be confidently filled into the tank.
Adviсe
Tips and life hacks can be extremely useful in practical work, let's look at some of them:
- It is convenient to use cans with dispensers, and experienced people filter gasoline through suede. The cleaner the fuel, the better the carburetor will work.
- Gasoline can actively evaporate, especially at high temperatures; a suspension forms at the bottom of the canister, which cannot be poured into the engine.
- It is recommended to prepare fuel for no more than three operational refuelings.
- The quality of the fuel can be affected by the material of the container; PVC materials react especially actively.
- If the combustible mixture was poured of poor quality, the chainsaw may be void of warranty.
- During operation, you should test the tightness of the containers and the rhythmic operation of the engine.
- One of the first signs of a malfunction is undue heating of the circuit.
- Before subjecting the tool to serious loads, you should test it at idle speed.
- The tank lasts for half an hour when working.
- There is still lubricant (residues) in the second container when the reservoir runs out.
- If a large amount of smoke appears during operation, this means that the fuel is of poor quality.
- While the unit is operating, do not approach open flames.
- (distance up to 2 meters).
- You should not fill the fuel “under the rim”; leave a little space.
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. 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. Plastic and glass react with gasoline, creating a flash fire hazard.
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.
