Proportion of Oil and Gasoline for Two-Stroke Engines: Instructions for Dummies

Proportion of oil and gasoline for two-stroke engines

The correct proportion of oil and gasoline for two-stroke engines will allow to achieve the best performance of the equipment. It is necessary to dilute two types of liquids in different proportions. Homius editors offer simple technical fluid dilution instructions for those who have just purchased a two-stroke engine.

Proportions of gasoline and trimmer oil

Regardless of what type of equipment you plan to use, you need to choose the right proportions and prepare the fuel mixture. The most common question: how to dilute gasoline with oil for a chainsaw and not make a mistake.

Before filling the fuel tank, a suitable product must be purchased. Unleaded fuel is best suited for gardening. It is ideal for such mechanisms. Before buying fuel, you must study the factory instructions for the equipment.

It is recommended to fill the lawn mower or other equipment with a tool with the number AI-90 or 92. After it became clear how much a liter of gasoline needs oil, the chainsaw is refueled and used for its intended purpose. It is best to purchase API TB branded formulations. They are suitable for use at positive air temperatures.

Trying to figure out how much oil to add to gasoline for a chainsaw, you should study the average proportions. Most often, the dilution is carried out at a rate of 1 to 50.

It is also important to determine the total volume, then it will become clear how much oil to pour into gasoline for a chainsaw. For a single job using special garden equipment, filling per liter is enough. If the tool is used regularly, then the average volume is 3-4 liters.

Powerful chainsaw consumes large amounts of fuel

The principle of the two-stroke engine

Each manufacturer of gasoline and fuel oils gives recommendations on the use of funds. In order for the chainsaw to work at full capacity, it is necessary to determine the required proportions: 1:50 (oil to gasoline). how much is it, it is important to choose the right ratio.

On the back of the package, as a rule, instructions for using fuel are attached.

The easiest way to learn how to mix 1:50 (oil to gasoline) is to use the data in the table:

Before pouring equipment, you need to correctly calculate the volume of each tool.

When preparing the fuel fluid, the total volume in liters is calculated

Gasoline and refueling oil sold separately

The ratio of oil and gasoline for two-stroke engines

Before starting work with the unit, it is necessary to prepare the fuel mixture. Regardless of which brand of gasoline is used, it is necessary to use one part of the liquid by mixing it with oil.

Standard performance when mixing formulations. 1 to 50

Five liters of gasoline use no more than 100 ml of oil. The exact amount is determined by the size of the equipment. Compliance with this ratio avoids the formation of soot on the motor elements.

For mixing, it is recommended to use special measuring containers. After combining, the fluids should acquire a uniform shade: brown, yellow or red.

For storage of gasoline you need to use special cans, but not plastic bottles. Gasoline quickly corrodes plastic.

How to prepare a fuel mixture. the rules and features of the process

Before mixing the oil-gasoline solution, you need to find out the exact proportions. The operation of any device, including chainsaws, must be carried out exactly according to the instructions attached by the manufacturer. The technical document indicates how much oil should be added per liter of gasoline.

To mix gasoline with trimmer oil, you need to study the characteristics of the device. If the distance between the pistons and cylinders is large, it is more difficult to maintain the normal operation of the mechanisms. Primary compounds are poured into a container for mixing gasoline and oil with a large medical syringe or in any other convenient way.

To dilute gasoline 1 to 50, you need to know for sure how much will have to be filled.

It is not recommended to mix oil and gasoline in the fuel tank

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 mixture is used. Equipment that uses synthetic oil is best suited for fuel diluted 1:50. It is necessary to select the right option in each case for a particular device.

Work is carried out in high-quality and tight gloves.

Once the ratio of oil to gas for the trimmer is determined, you can refuel the device.

Pouring liquids into the tank is better in the open air, rather than in the garage

Recommendations for the preparation of the mixture and filling the gas tank:

To find out how to dilute gasoline with oil for the trimmer, you need to study the instructions for the device.

Always check the expiration dates of gasoline and oil

The ratio of oil to gasoline

Depending on the model of equipment and engine type, refueling with gasoline and oil is carried out in different proportions. It is important to make the right choice so that the working mechanisms serve as long as possible.

Before you dilute gasoline with oil for a trimmer or chainsaw, you need to determine the required amount of one and the other fluid. The ratio of gasoline and oil for a chainsaw can be different: 1:50, 1:40 or 1:25.

Manufacturers offer a huge amount of funds

The amount of gasoline must be determined in liters, and the oil is calculated in ml.

Preparation of a mixture for processing chainsaws

Before using the equipment, the proportions of gasoline and chainsaw oil are determined.

Before you dilute gasoline with chainsaw oil, you need to prepare a special canister. Plastic and glass bottles will not work, and you can’t pour the product directly into the tank. To find out how much oil per liter of gasoline needs to be poured into the trimmer is easiest from the instructions attached to the equipment.

Fuel must be stored for up to one month. Then the mixture is oxidized, due to which its properties change.

Proportion of oil and gasoline for outboard motor

Two-stroke engines for a boat are necessarily filled with a home-made solution of two types of fuel. To find out how much oil to add to gasoline for a trimmer or motor, you need to consider the stages of equipment operation:

  • primary run-in. a 1:25 dilution is required;
  • long work. 1:50;
  • short work period. 1:40.

After the factory packaging is opened, the properties are stored for six months, however, the manually prepared mixture is stored for no more than a month.

The manufacturer should always indicate in the instructions for the motor boat which solutions are suitable for the particular model. To find out how much oil to pour into gasoline for a trimmer or outboard motor, you need to familiarize yourself with the factory documents.

It is recommended that you have a supply of the mixture in the canister when swimming to refuel the motor if necessary


Before using the working equipment, it is necessary to find out in what quantities to mix gasoline and oil. Compliance with the technical requirements of operation will extend the life of the device for a long time.
