Important: the use of mineral, semi-synthetic and synthetic automotive oils is prohibited. They are designed for other types of motors and do not have the required properties.

Chainsaw Basics: Fuel and Oil

Fuel mixture working proportions

The standard gasoline to oil mixture ratio for carburetor chainsaw engines of various models is 40: 1 and 50: 1. This proportion provides full lubrication of the rubbing parts of the crank mechanism and piston group, and also does not prevent the complete combustion of the gasoline-air mixture.

Taking into account external factors, the fuel mixture can be adjusted in the direction of increasing the amount of oil. Such a need arises at the stage of running in a new tool, as well as at high air temperatures. In this case, the standard oil dosage 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 case is determined by the sawman himself.

How to dilute gasoline for a chainsaw

Consider how the mixture is prepared for a chainsaw. It is necessary to calculate the correct ratio of gasoline and oil for the chainsaw. For a chainsaw, they take fuel with a high octane index: AI-92 or AI-95.

To prepare the fuel mixture, it is necessary to add 30 g of oil to 1 liter of gasoline, which corresponds to the design of the saw. The resulting fuel fluid is poured into the fuel compartment. Before diluting gasoline, you should consult a service specialist who specializes in the repair of chainsaws.

In order for the saw to have a long service life, it is necessary to properly prepare a gasoline-oil mixture, for which only AI-92 and AI-95 brands can be used. The fuel must be unleaded, otherwise the internal combustion engine may break down. Do not use an old product that has expired, because over time, the fuel can change the octane number. The proportion of lubricant and fuel is strictly adhered to.

You should not save when choosing oil for Husqvarna chainsaws and others. The proportions must be observed due to the fact that excess oil can lead to the growth of carbon deposits on the chainsaw units. Excess gasoline can cause damage to the piston and damage to the internal combustion engine. So, 1 liter of fuel is mixed with 20-50 ml of oil. Husqvarna recommends adding 100 ml of grease to 4 liters of gasoline. This proportion is suitable for saws with a power of up to 1.5 kW.

For structures with a power of more than 1.5 kW, an oil ratio of 1:50 is used. That is, it is necessary to dilute gasoline like this: add 5 liters of gasoline for a chainsaw to 100 ml of oil. Partner recommends when refueling the chainsaw with fuel, dilute the fuel fluid at the following rates: add 100 ml of lubricant to 3.3 liters of fuel.

When using supersynthetic oils, the indicators are 1: 100. That is, the fuel mixture for the chainsaw must be prepared according to the recipe: add 100 ml of lubricant to 1 liter of fuel. When choosing components, you need to use the information that is given in the instructions for any modification of the saw.

Plastic bottles and other containers are often used to mix ingredients. Be careful with plastic and glass. Mixing the components may generate static electricity. Care must be taken to prevent pebbles, sand or water droplets from entering the fuel mixture. The fuel mixture must be mixed well. The prepared fuel mixture should not be stored for more than a month, as oxidation of materials may occur and the composition of the mixture will change.

Engine breakdown, which was caused by expired fuel, is recognized in the services not under warranty. At the same time, the cost of repairs can reach 80% of the price of a new design.

After all work with the use of the chainsaw has been completed, you need to spend the remaining fuel, turn off the engine, remove the remaining mixture.

For the best operation of the device, it is necessary to make a mixture that will ensure uninterrupted operation of the engine, complete combustion of the gasoline-oil mixture without the formation of carbon deposits, smoke or damage.

What should be the proportions of oil and gasoline to prepare the fuel mixture of a chainsaw

The chainsaw is started with an engine running on a mixture of gasoline and oil adapted to the ambient conditions. It is necessary to observe the proportions of oil and gasoline for the chainsaw, then the device will work stably. To achieve high power, the saw is used at high engine speeds. Therefore, increased requirements are imposed on the quality of lubricants and fuel.

Lubricants

Stricter criteria for the selection of the oil component. In the best variant, it is a mineral or semi-synthetic engine oil recommended by the manufacturer, intended for operation 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 counterparts are distinguished by improved performance and compliance with environmental standards.

Synthetics:

  • maintain working properties in a wide range of operating temperatures;
  • do not form carbon deposits;
  • contain detergents, antioxidants, preservatives and other additives useful for the operation of the power unit.

Petrol

The main component of the fuel mixture for chainsaw engines is gasoline with an octane number of at least 92. Consumables with expired storage, made on the basis of gas condensate, having water and mechanical impurities in their volume are not suitable for fuel preparation.

  • The opinions of experts on the use of different brands of gasoline are ambiguous. On the one hand, the incomplete compliance of domestic gasoline A-92 with European standards is recognized.
  • On the other hand, the quality of A-95 gasoline is questioned due to the high content of anti-knock additives. You can use this fuel to prepare fuel for a chainsaw only if you are fully confident in its quality.
  • The difficulty lies in the presence of various improving additives, with the help of which unscrupulous manufacturers and distributors increase the performance properties of motor gasoline with a lower octane index.

Also, irreversible changes in the working properties of the fuel occur when it is stored for a sufficiently long time in a plastic container, regardless of the level of its petrol and oil resistance.

A mixture of gasoline and oil for two-stroke engines

When buying equipment, you should study the instructions. in it, the manufacturer can recommend the best way to prepare the fuel mixture. For air cooled models a 1:40 mix is ​​used.
