How to dilute fuel for a chainsaw. Characterization of household chainsaws
Gasoline for a chainsaw: what kind of pouring?
Since the chainsaws use a two.Stroke engine, where it is not constructively impossible to install an oil pump, pure gasoline cannot be poured into a chainsaw! A fuel mixture of gasoline and oil is poured into the chainsaws. The proportions for different saws are set by the manufacturer, the specific number is indicated in the operating instructions.
The question is often asked: gasoline for a chainsaw-kakha pour? I will try to answer in more detail
Preparation of fuel mixture for a chainsaw
Gasoline should be with an octane number no less than AI92. You can also fill in AI95, but its quality at our gas station leaves much to be desired, so if you are not sure of the 95th, it is better to take gasoline AI92 gasoline to dilute gasoline into a chainsaw. You should not take gasoline in the same way for a long time in the canister, tank or any other capacity. Gasoline for the preparation of the fuel mixture in the chainsaw should be fresh, otherwise it loses its properties, in particular the octane number, and even if you run the chainsaw on such fuel, it will not give out full power. And the saddest thing in this case is that the failure of the chainsaw due to poor.Quality fuel is considered a non.Warranty occasion and leads to expensive repairs. Sometimes it’s easier to buy a new chainsaw than to repair it after such a breakdown!

In what proportions to mix liquids?
Each manufacturer of chainsaws determines its proportions for obtaining a gasoline-oil mixture and indicates this in a technical passport that is attached to the tool when buying. Gasoline proportions with oil for chainsaws of domestic production are most often recommended in a ratio of 1:15 or 1:20. In order to calculate how much oil is required per liter of gasoline, you need 1000 /15 = 65 ml and 1000 /20 = 50 ml. In the first case, 65 are added to each liter of gasoline, and in the second. 50 ml of oil. For imported technology, the proportion is slightly different.
For the Husgvarna chainsaw, the engine power of which is 2 kW, the manufacturer advises using the ratio of 1:50, t. E. 20 ml of oil is added to each liter of gasoline. Chinese.Made saws are required to pour 40 ml of oil per liter of gasoline with a ratio of 1:25. It should be remembered that with excess oil in gasoline, the soot increases, the cylinder clogs, piston rings are damaged and compression decreases. With a lack of oil. The engine overheats and the productivity of the tool is sharply reduced. When the documentation is lost and you do not know how to mix gasoline with oil for a chainsaw, you can contact the service center for the necessary information.
How to breed gasoline for a chainsaw
Consider how the mixture for the chainsaw is preparing. It is necessary to calculate the correct ratio of gasoline and oil for chainsaw. A fuel with a high octane indicator is taken for a chainsaw: AI-92 or AI-95.
To prepare the fuel mixture, it is necessary to add 30 g of oil by 1 liter of gasoline, which corresponds to the construction of the saw. The resulting fuel fluid is poured into the fuel compartment. Before breeding gasoline, you should get advice from service specialists who specialize in the repair of chainsaws.
In order for the saw to have a long service life, it is necessary to correctly prepare a gasoline mixture for which only AI-92 and AI-95 brands can be used. The fuel should not be ethyled, otherwise the internal combustion engine may break. You can not use an old product that has expired, because over time, fuel can change the octane number. The proportion of lubrication and fuel is strictly withstanding.
You should not save when choosing oil for chainsaws of the brand Husqvarna and others. The proportions must be observed due to the fact that excess oil can lead to growth of soot on the nodes of the chainsaw. Excess gasoline can provoke the occurrence of damage to the piston and DIS breakdown. So, 1 liter of fuel is mixed with 20-50 ml of oil. Husqvarna recommends add 100 ml of grease by 4 liters of gasoline. This proportion is suitable for saws with power up to 1.5 kW.
For structures with a power of more than 1.5 kW, an oil proportion 1:50 is used. That is, dilute gasoline as follows: add gasoline for a chainsaw in an amount of 5 liters per 100 ml of oil. Partner recommends diluting the fuel fluid in the following norms when refueling the chainsaws: 100 ml of grease is added by 3.3 liters of fuel.
When using supersynthetic oils, the indicators are 1: 100. That is, the fuel mixture for the chainsaw should be prepared according to the recipe: add 100 ml of lubricant per 1 l fuel. When choosing components, you need to use the information that is given in the instructions of any modification of the saw.
Consider which container you can mix fuel. The stores have canists with measuring divisions in which there are 2 holes: for fuel and for lubrication. Using such a canister, pour both ingredients, tighten the lids and mix the substances, tilting the canister in different directions.
Often, plastic bottles and other containers are used to mix ingredients. With plastic and glass, you should be careful. When mixing components, static electricity may appear. It is necessary to ensure that pebbles, sand or drops of water do not get into the fuel mixture. The fuel mixture must be mixed well. The prepared fuel mixture cannot be stored for more than a month, since the oxidation of materials may occur, and the composition of the mixture may change.
Breakdown of the motor, which was caused by fuel with an expired shelf life, is recognized in the services of non.Warranty. At the same time, the cost of repairs can reach 80% of the price of a new structure.
After all the work using the chainsaws were over, you need to spent the remaining fuel, turn off the motor, remove the remnants of the mixture.
For the best operation of the device, it is necessary to make a mixture that will ensure uninterrupted operation of the motor, complete combustion of a gasoline mixture without soot, smoke or damage.
Option of alternative fuel
As an alternative, many are offered to refuel gasoline AI95, but the question remains controversial. In theory, the characteristics of such fuel are better, but in practice it is better not to risk and refuel a chainsaw with ordinary, Soviet ai92.

The main nuance is that the AI95 is introduced, individually selected by the fuel manufacturer. In some cases, such additives can negatively affect the operation of a two.Tint engine.
Gasoline and oil proportions for STIHL grass
The German manufacturer of high.Quality cutting tools STIHL, in addition to chainsaws, produces motor mowers. This is an indispensable tool for mowing grass and trimming the lawn, characterized by lightness and mobility.
A lawn mower, or a trimmer for grass, also has a two.Stroke engine and is seasoned with a fuel mixture. For a trimmer for STIHL grass, a ratio of 1:50 is recommended (5 liters of gasoline 100 ml of oil).
Most drivers know that a two-stroke engine operates on a gasoline oil fuel. Therefore, it is recommended to comply with the proportions indicated in the processport of the product.
Of course, some owners of vehicles with extensive experience create a proportion “by eye”. However, each time a similar mass will have a different ratio. This will adversely affect the work of the motor. Therefore, you need to familiarize yourself with the instructions on the package.
Recommended requirements for the operation of the mixture:
- Do not reduce the amount of the oil component when mixing with fuel. You need to adhere to a ratio of 1 to 50. This is how much oil? You need to know the exact amount before filling the mixture into the crankcase. Oil is not cheap, so they often try to save on it. But this can contribute to a strong heating of the system. Therefore, the proportions of the oil should be observed. Also, due to the insufficient amount of this component, scuffs may appear, which significantly reduces the duration of operation of the motor.
- Also, a plentiful amount of oil should not be used. Excess of its volume is a negative factor for engine operation. This leads to the rapid wear of the motor, to an increase in soot.
- It is not recommended to store the prepared fuel mixture for more than 30 days. Otherwise, it loses the desired properties, and its use will significantly reduce the life of the engine.
- It is required to ensure that there is no dust, dirt in the composition, as this is also negatively affecting the work of the motor.
What will happen if the manufacturer’s recommendations do not take into account?
In case of violation of the rules for the preparation of fuel and lubricants and non-compliance with proportions when adding oil to gasoline at the Stihl 180 chainsaw; the following problems arise:
- With an increase in friction, the wear of the working surfaces of parts will increase.
- Due to the insufficient amount of the lubricant, the bearings will begin to collapse.
- The full functioning of the mechanical nodes is violated in connection with the premature wear of the parts, their service life is significantly reduced.
- When using low.Grade varieties of gasoline and oils, the performance of the unit decreases with subsequent breakdown of important nodes and parts.
Fuel is prepared before refueling the saw, avoiding excessive contacts with oxygen. After the end of work, the remaining mixture must be drained.
What will happen if you fill in the workout
Using a spent car oil for a chainsaw is strictly prohibited. After such an abuse, the engine quickly fails.
Washing is an oil that has already developed its. It is not able to further ensure high.Quality sliding of the parts. This is a consumable from a four.Stroke engine, which is already bad, and it will be full of metal chips removed from the pistons and cylinders during the previous use. The particles of steel make it difficult to move the mechanisms, scratch them, leave the bullying. Even mixing a pair of grams of working for suitable oil will reduce the duration of the saw and tool with a two.Stroke engine.
Please note: there is no clean training. If garbage and chips are not visible, this does not mean that they are absent in oil.
Only competently mixed fuel using high.Quality materials provides stable gas tools for its working function.
