Requirements for the fuel used
The main fuel component of a carburetor engine is unleaded gasoline. You should not experiment with the question of what gasoline to pour into the chainsaw. Its brand must comply with the requirements set forth in the instrument’s passport and instructions for its operation. Violation of this rule may result in:
- To a sharp decrease in the power of the saw and the unevenness of its work in the case of using gasoline with a lower octane number;
- To overheating of engine elements when the recommended octane number exceeds the rating.
It is strictly forbidden to dilute gasoline for a chainsaw with dubious mixtures, so you should use the services of the nearest gas station. It must be remembered that in addition to the octane number in automobile fuel, there are many other indicators, which vary depending on the season.
Fuel mixture preparation rules
It is recommended to prepare the mixture for the chainsaw immediately before starting work. Storing it for more than 10 days can lead to chemical reactions between the additives that make up the oil and the components of gasoline. This will negatively affect engine performance and exhaust gas composition.
Dilute oil in gasoline in the proportion recommended by the tool manufacturer. For different models, the ratio can vary from 1:20 to 1: 100. For the Stihl 180 chainsaw, it is 1:50. This means that for 1 liter of AI-92 gasoline, you need to take 20 ml of oil. Deviation from THESE numbers can affect engine performance:
- A decrease in the proportion of oil will lead to mechanical wear of the cylinder and piston;
- Excessive amount of oil will cause incomplete combustion of the mixture.
It is strictly forbidden to use oil intended for the second types of motors for two-stroke engines, especially working off.
What gasoline to pour into a chainsaw
Chainsaw is considered the most popular type of hand tool used for working with wood. Unlike electric dust, it is adapted for autonomous use, which is a convenient, and sometimes the only possible effective way to cut logs and other wood materials in remote areas. To do this, you just need to have on hand fuel for the chainsaw in the required amount and know the rules for refueling the tool.
How is mixing done
In order not to spend a lot of time on preparatory operations and NOT to store a large amount of the fuel mixture, it is usually prepared in an amount equivalent to 3-4 refueling of the chainsaw. Mixing can be done correctly only with measuring utensils.
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 that, dilute the gasoline, add oil to it. It is convenient to measure it using a syringe of the desired size 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 shade by which it can be easily distinguished from pure gasoline and confidently filled into the tank.
Purpose of oil
Since the two-stroke engine is NOT equipped with a lubrication system, it is necessary to refuel the chainsaw in advance with a mixture of gasoline and special oil. On domestic models, the brands M8, M12, MGD-14M are often used. Well-known foreign tool manufacturers Insist on using their own brand oils, which are developed in cooperation with leaders of the oil refining industry. But practice shows that replacing one high-quality oil for two-stroke engines with a second one does not negatively affect the characteristics and duration of equipment operation.
According to the method of production of the base of motor oils, they are divided into:
- Mineral;
- Semi-synthetic;
- Synthetic.
In this list, they are listed in ascending order of quality and price. So if you add Stihl synthetic chainsaw oil to your Husqvarna chainsaw, She won’t notice the difference.
Chainsaw fuel system device
Most modern chainsaws are powered by a single-cylinder, two-stroke internal combustion engine running on 92 or 95 gasoline. Old domestic models must be refueled with 80 octane fuel.
The speed of the chain drive is determined by the speed characteristics of the motor, which usually exceed 10,000 rpm. Therefore, the fuel mixture for a chainsaw equipped with a high-speed engine must contain special engine oils.
Chainsaw fuel system includes:
- Filling tank;
- Fuel filter;
- Carburetor;
- Hoses through which fuel is supplied for mixing with air and further into the engine cylinder.
The fuel filter is attached to the end of the hose, dropping into the tank. When the engine is running, a small pump built into the carburetor ensures uninterrupted pumping of fuel. To start the engine, mechanical pumping of gasoline is required with an additional device. a primer. A special air valve protects the tank from creating a vacuum when the liquid level drops during operation. The carburetor is responsible for the correct ratio of fuel to the forced air in the process of creating a fuel-air mixture that is fed into the cylinder for combustion. The entire fuel system works in concert with the ignition system in time with the movement of the piston.
How much gasoline does a chainsaw consume
The fuel tanks of most petrol dust have a volume of 0.3 to 1.0 liters. How often you need to pour the fuel mixture into the chainsaw depends on the chosen brand, engine power and work intensity. For logging and wooden construction, professional chainsaws are used, characterized by high power and a long period of continuous operation. For housekeeping in a village house, in the country or in the periodic manufacture of wood products, less productive, but light and convenient household models are used. For a professional tool with a power of 5-6 kW, fuel consumption when sawing logs can reach 3.0 l / h. In less powerful models with a 1.5-2.0 kW engine, it fluctuates at the level of 0.6-0.8 l / h.
The proportion of oil and gasoline for a chainsaw: how to dilute
All modern chainsaws are equipped with a two-stroke engine. Its long and trouble-free operation directly depends on whether the proportion of oil and gasoline is correct for the chainsaw. The variety of tool brands and the features of each of them are a prerequisite for the fact that this procedure is not easy for most novice users of chainsaws.
Why you need to mix oil and gasoline
When using the saw, gasoline should always be mixed with oil. The reason for this is the design features of a two-stroke internal combustion engine. It does not have a dedicated lubrication system for parts (as in other GIS) and, accordingly, its cylinders with O-rings, crankshaft, bearings and connecting rods Must be lubricated directly in the process of obtaining fuel.
Fuel mixture
To properly prepare the fuel, a list of additional tools is useful:
- Plastic on the second iron container for diluting the substance;
- Measuring bottle for gasoline;
- Dispenser;
- Syringe;
- Chainsaw tank filling can.
Some Russian auto industry, such as Stihl, immediately make measuring containers for more comfortable measurement of the fuel consistency.
Various Russian automotive industries produce oils of various colors. HP produces a reddish liquid. Oil of a greenish tint is the premium synthetic sector. For your Husqvarna chainsaw, use the correct oil grade. It is distinguished by the highest price, good quality and has a greenish or blue color.
Filling the Stihl MS180 Chainsaw, petrol and butter.
Chainsaw Stihl MS180 A couple of moments of what is really, what kind of water needs to be poured into the chainsaw. Always keep an eye on.
The main thing is to correctly calculate the proportions of the mixture. Excess oil can form carbon deposits on pistons and spark plugs. Excessive gasoline can cause engine damage or piston seizure. Each manufacturer gives its own proportions to models of different power.
To mix the components, you will need the aforementioned additional accessories. Also on sale you can find special canisters with two holes for oil and gasoline. Everything is very simple here, pour in the ingredients, tighten the lid tightly and mix by tilting the container. Glass and plastic bottles can be used.
No water or dust must get into the fuel mixture.
The ratio of the amount of oil and gasoline for the fuel mixture
The proportion of oil and gasoline for a chainsaw is usually made up according to two recipes:
- 50 servings of gasoline per serving of engine oil
- 40 servings of gasoline per serving of engine oil
If the chainsaw was recently purchased and has NOT yet been operated, then the fate of the lubricant is increased by a quarter. The same amount is poured into fuel when cutting at temperatures below 2 degrees.
It is NOT difficult to get such a mixture. Almost every modern saw is equipped with a special two-section container. Oil is poured into a smaller part of it, and gasoline is poured into a larger part. The lids of both parts are tightly twisted and the container is turned over, shaken thoroughly. This achieves a complete and homogeneous mixing of both components.
If there is such a special container, then you can use any gasoline-resistant plastic container with a one liter lid and a disposable syringe for 5-10 cubes. The gasoline tank must first be cleaned of various kinds of pollutants and water. After that, one liter of 92-95 gasoline is poured into it.
In parallel, 20 ml of oil is drawn into the syringe. If refueling is done in cold weather, then you need to take 24-30 ml. Gently pour it into a container with gasoline. It is tightly closed with a lid and shaken thoroughly until the components are completely mixed.

Fuel consumption
One of the most fundamental questions that arises in the owners of the saw tool, because everyone wants to know what he can count on.
The volume of almost all tanks is approximately 500 ml. If the power of the chainsaw is 2 kW, then the consumption of the fuel mixture will be approximately 1.2 liters during operation. Simply put, such a tool will be able to work at maximum speed for half an hour without interruption. If the chainsaw is not so powerful, then the volume of the tank will be smaller. So users can independently control fuel consumption.
Over time, the user will learn to service his tool without any help. The main task will be to preserve the economic unit in good, working condition, using high-quality fuel mixtures. Observe safety rules when preparing flammable water. This will help preserve the instrument, and also not harm yourself and the environment.
What kind of gasoline to pour into the chainsaw. Step by step instructions for refueling
If you want to refuel your chainsaw, you need to follow a simple algorithm:
Alternative fuel option
For refueling household and professional chainsaws, it is recommended to use non-alcoholic components and additional additives. motor gasoline type AI-92.
The question of whether it is possible to pour 95 gasoline into a chainsaw is still controversial. Theoretically, the anti-knock properties of AI-95 gasoline are higher than that of the 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 characteristics, manufacturers and distributors introduce additives into the 95th gasoline, the quality and effectiveness of which raises reasonable doubts among specialists.
Such fuel does NOT fully meet the required characteristics, does not have the proper stability during long-term storage. After 3-4 months of exposure, its performance deteriorates by 25-30%.

Why dilute gasoline with chainsaw oil?
The two-stroke engine is less economical in terms of fuel consumption, but it has more power per unit volume. The four-stroke engine is mainly installed on vehicles such as cars, tillers, mowers and others. For a four-stroke engine, an important indicator is its efficiency. The efficiency index in a four-stroke engine will always be higher than in a two-stroke engine. In other words, these two types of engines have different tasks and purposes.
Fuel mixture
To properly prepare fuel, you need a list of additional tools:
- A plastic or metal container for diluting the substance;
- Measuring bottle for gasoline;
- Dispenser;
- Syringe;
- Chainsaw tank filling can.
Some manufacturers, such as Stihl, immediately make measuring containers for more convenient measurement of the fuel mixture.
Different manufacturers produce oils in different shades. HP produces a red liquid. Green oil is a premium synthetic segment. For your Husqvarna chainsaw, you need to use the correct oil. It is of high value, good quality, and is green or blue.
To mix the components, you will need the aforementioned additional accessories. Also on sale you can find special canisters with two holes for oil and gasoline. Everything is very simple here, pour in the ingredients, tighten the lid tightly and mix by tilting the container. Glass and plastic bottles can be used.
No water or dust must get into the fuel mixture.
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, therefore, pouring pure gasoline into the chainsaw is strictly prohibited! The proportions, quantity and some brands are indicated by the manufacturer in the instruction manual.
Important points in the cooking process:
- Domestic chainsaws work with oil M8-B, M-12TPU, M8-B, TP, MGD-14M. In some cases, you can use foreign options;
- Proportions: 2.5 liters of FI-80 gasoline per 100 grams of oil;
- Foreign models are distinguished by minimal fuel consumption. They work on foreign oils, and their proportions become 1:40 or 1:50.
Risks of using fuel and oil surrogates
The design features of the internal combustion engine of domestic and imported chainsaws exclude the use of more affordable biofuel and gas condensate gasoline substitutes. The performance characteristics of such a fuel are currently far from perfect.
In the total sales of motor oils, counterfeit lubricants, according to various sources, account for 8 to 15%. Only an experienced specialist can distinguish an original product from a fake.
To eliminate possible risks of early breakdown of the saw, it is recommended to purchase consumables in branded outlets and representative offices of dealer companies.
With all the external similarity, it is forbidden to use oils for two-stroke internal combustion engines of mopeds and light motorcycles to prepare a working fuel mixture. The use of non-recommended lubricants may initiate a denial of warranty by the service department.
Gasoline recommendations
By current standards, the best gasoline for a chainsaw should be NOT leaded, high octane, and reasonably fresh. High degree of purification from impurities is welcomed.
- Filling the fuel system with fuel more than half a year old storage, adversely affects the traction characteristics of the internal combustion engine, contributes to carbon formation and the occurrence of detonation phenomena.
- For beginners and experienced users, it is advisable to exclude low-octane gasoline for chainsaws, as well as cheap engine oils of unknown origin from the scope of their attention. The use of leaded fuel is NOT prohibited, but in order to extend the life of the saw, it is best to refuse its use at the selection stage.
Practice shows that saving on the quality and cost of consumables negatively affects the performance of chainsaw equipment and the duration of its full operation.
