The proportion of oil and gasoline for the Ural chainsaw

What oil to choose for a chainsaw?

The operation of a two-stroke engine has significant differences from a four-stroke engine, which, first of all, are in the operating cycle. For the correct functioning of a two-stroke engine, a special fuel mixture is needed. gasoline with oil.

Which chainsaw oil to choose?

In order for the chainsaw to work for a long time and without breakdowns, you should strictly adhere to the manufacturer’s tips and recommendations. About chainsaw repair Ural already told earlier. The problems were a clogged air filter and adjusting the jets of the chainsaw.

Little attention has been paid to the correct preparation of fuel for the chainsaw, as it can also cause breakdowns or problems in the operation of this gasoline tool.

Chainsaw oil is best used as recommended by the manufacturer. First of all, this is a two-stroke oil, the ratio of which to 76 grade gasoline should not be more than 4%.

In this case, the proportions of oil and gasoline for the chainsaw should be approximately 1:25. But this value is true only for domestic chainsaws and AI-76 gasoline used for their operation.

The proportion of oil and gasoline for a chainsaw

In the case of foreign-made chainsaws, things are a little different.

For the use of foreign chainsaws, as a rule, gasoline is used not lower than 92-95 brands. In addition, a special branded oil from the manufacturer is used for it. In this case, most often, the proportion of oil and gasoline is not 1:25, but 1:40.

To lubricate the chainsaw chain, any “Zhiguli” oil is suitable. Many are also used for these purposes and testing, but here you need to act at your own peril and risk, since it is not recommended to use it to lubricate the chain due to rapid oxidation.

To correctly determine the proportions of oil and gasoline for a chainsaw, you can use special measuring canisters. They make it possible to very quickly prepare fuel of the desired consistency.

To refuel the chainsaw, use only the oil that meets all the requirements and operating conditions of a two-stroke engine. Only in this case it will not be required repair of the TAIGA chainsaw or any other.

What will happen if you do not take into account the manufacturer’s recommendations?

In case of violation of the rules for the preparation of fuel and lubricant mixtures and non-observance of the 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.
  • Insufficient lubricant will cause bearings to deteriorate.
  • The full functioning of mechanical assemblies is disrupted due to premature wear of parts, their service life is significantly reduced.
  • When using low-grade grades of gasoline and oils, the performance of the unit decreases with the subsequent breakdown of important components and parts.

The fuel is prepared before refueling the saw, avoiding excessive contact with oxygen. After finishing work, the remaining mixture must be drained.

The proportions of gasoline and oil for chainsaws: features of the preparation of the fuel mixture

The fact that it is prohibited to pour “clean” gasoline into chainsaws is warned by sellers of buyers at the time of purchasing the tool. Many buyers learn about this for the first time, wondering why it is necessary to dilute gasoline with oil. If you neglect this rule, then the consequences for the tool can be simply catastrophic. In most cases, even a major overhaul of the engine will no longer be able to help. In the material, we will find out what the proportions of gasoline and oil should be for refueling a chainsaw, and also what the risk of non-compliance with this rule.

The ratio of gasoline and oil for refueling a chainsaw

After choosing gasoline and oil for the chainsaw, you need to decide on their proportions that are required for breeding. The first mixture should have a grade not lower than AI92, AI95 is the best option. Let’s take a closer look at what the proportions of the oil product and fuel for a chainsaw should be. As a rule, equipment owners use 20-50 ml of oil component per 1 liter of fuel.

The ratio of gasoline and oil for refueling a chainsaw

If the question is how much oil to pour into gasoline for a chainsaw with a low power, for example, 1.5 kW, then 25 ml per 1 liter of fuel will be required. The high power saw mix is ​​prepared from 30-40 ml of oil product. For more information, refer to the instructions for use of the lubricant or not directly on the packaging.

Shelf life of the finished fuel mixture

Motorists know that it is not worth storing gasoline for a long time, and the finished fuel mixture deteriorates even faster. It is necessary to mix the required proportions of oil and gasoline for the STIHL chainsaw before starting work. Manufacturers allow storage of finished fuel for up to one month, and experts recommend that this period be reduced to 10 days. Immediately after mixing, the solution begins to lose its original properties and over time it becomes not at all of the same quality as it was prepared. Learn to prepare enough saw fuel to be consumed in one go. It comes with experience. The mixture should be stored in a gasoline-resistant, opaque, tightly closed container. For this, any cans made of plastic metal for combustible materials are suitable. And also use a container from under oil or glass containers made of dark glass.

The gasoline / oil mixture is best prepared in a 2.5 liter plastic bottle if you have to refuel the tool frequently. If you need to prepare fuel for just a few fillings, then it is better to use a smaller container. It is definitely recommended to acquire measuring containers, this will allow you to maintain the exact proportions of both liquids. Most oil manufacturers offer such measuring devices.

Initially, fuel is poured into the container, and then oil is added. It is imperative to take into account that there must be enough space in the container to thoroughly mix the fuel mixture.

It’s important to know! It is categorically contraindicated to prepare the fuel mixture directly in the gas tank of the tool.

After preparation, it is recommended to store this mixture for no more than 2 weeks. It is recommended to shake the mixture thoroughly with each filling. If you are not sure that all the fuel will be used up, then it is better not to cook it in large quantities.

Ratio of oil and gasoline for chainsaws

How much oil to add to gasoline for a chainsaw is indicated, first of all, in the operating instructions for the tool. If you have forgotten what the proportion of oil and gasoline should be, then you can always open the instructions and update your knowledge. If the instructions are lost, then this material will help you. To begin with, it is worth noting that there are several options for mixing oil materials with fuel. Choosing any, it is worth noting that the main criterion for each is the correctness of measuring the components. Only the exact observance of the proportion of oil and gasoline will allow achieving the fuel mixture of the required technical qualities.

One of the most common proportions is 1:50. This means that 1 liter of gasoline must be diluted with 20 ml of oil. Such a recipe for preparing a mixture is relevant for tools whose power exceeds 1.5 kW. This option is one of the most popular, so if you have forgotten the exact proportions for your instrument, then you can always focus on the first option.

The second option provides for a ratio of 1:25. Mixing 1 liter of gasoline with 10 ml of oil is recommended by Chinese manufacturers for their tools. For tools whose power does not exceed 1.5 kW, it is recommended to pour oil in the amount of 25 ml per 1 liter of gasoline. Each manufacturer’s chainsaws have their own restrictions, and recommendations for preparing a fuel mixture, which are recommended to be followed. The above are two main options that are universal.

It’s important to know! An excessive amount of the oil mixture in the fuel is also negative, since this will lead to a reduction in the engine resource due to increased shock loads on the cylinder and piston, and will also entail the formation of carbon deposits.

Not everyone knows what kind of gasoline to pour into the chainsaw. This is also indicated in the technical documentation for the chainsaw. In modern saw models, it is recommended to pour fuel of a grade not lower than AI-90, that is, AI-92 or AI-95. And it doesn’t matter who the tool manufacturer is, China or Europe. Professionals recommend using AI-92 gasoline, since in Russia the 95th is in most cases produced from 92 by adding additives. If you know for sure that this is really pure 95, then it is better to use it.

Many craftsmen continue to pour gasoline of grades lower than AI-90 into modern models of chainsaws, as it was allowed to do this for outdated models of tools: “Friendship”, “TAIGA” and others. This is not recommended.!

Which oil to use to lubricate the chainsaw chain depends directly on the model of the tool. STIHL branded saws and the like produce special lubricants that are intended only for use in such tools. Recommended oils can also be found in the technical documentation. When choosing a lubricant, you must pay attention that it is necessarily intended for two-stroke engines. Oils for mixing with gasoline and for lubricating chains differ in composition, quality and purpose. You cannot mix them, as this will accelerate the failure of the instrument. Recommended oil brands for two-stroke engines:

  • STIHL;
  • Kreissman;
  • Husquarna;
  • Sadko.

How to prepare the mixture?

In order for the equipment to serve for a long time and properly cope with its functions, you need to know exactly how much oil you need to add to gasoline for the STIHL chainsaw. Earlier, we found out that it is better to use a lubricant product from the STIHL manufacturer and AI92 or AI95 unleaded gasoline as components. Leaded fuel grades adversely affect the operation of the unit and disable it. With these components, 20 ml of oil is added to the mixture per liter of gasoline. Any violation of the proportions leads to the appearance of carbon deposits on the spark plugs and pistons, as well as the formation of scoring. The oils used can be green, blue or red.

Their presence is easily determined by the color of the mixture. To dilute fuel, often complete with equipment, a special canister is attached. These containers have graduated marks and two holes. The user only needs to fill the tank with the components of the mixture to the required marks, close the lids and mix. Some people use plastic bottles and syringes to measure oil for this purpose. In this case, it is necessary to ensure that foreign particles or water do not get into the container, all this will worsen the operation of the engine.

Storage advice

The mixture must be prepared in the amount necessary to carry out a small amount of work, since with long-term storage of the solution, its quality characteristics deteriorate. The prepared mixture must be spent within several days.

A fuel mixture that has been stored for about a month will reduce engine performance. Resinous substances are formed in the nodes, and carbon deposits appear, the piston rings lose their mobility. The longest shelf life of the mixture is no more than 2 weeks. During this period, the solution will not lose its quality. If the air temperature is more than 25ºC, then the shelf life of the product is reduced to 10 days.

Some experts allow the use of an expired mixture to save money. To do this, it can be spent gradually, gradually mixing it into a fresh solution in a volume of no more than 10% of the total amount of the mixture. The finished gasoline-oil mixture must be filtered.

If you follow all of the above recommendations, then you can ensure the reliable operation of the chainsaw. Also, when performing work, safety precautions must be observed, since the chainsaw works using a chain rotating at high speeds and, if the rules of operation are violated, it can pose a danger to the worker himself and the people around him.

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:

proportion, gasoline, ural, chainsaw
  • 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 proportion of 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 no such 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 tank for gasoline must first be cleaned of various 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. We carefully pour it into a container with gasoline. It is tightly closed with a lid and shaken thoroughly until the components are completely mixed.

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 internal combustion engines) and, accordingly, its cylinders with O-rings, crankshaft, bearings and connecting rods must be lubricated directly in the process of obtaining fuel.

Risks of using fuel and oil surrogates

To avoid premature failure of the chainsaw, it is recommended to refuel the tool with exclusively high-quality and branded consumables. Finding such materials is not difficult, as they are usually sold in branded retail outlets. The use of low-quality gasoline can lead to engine failure, therefore, it is recommended to buy fuel at such filling stations where high-quality fuel is guaranteed.

It is categorically contraindicated to mix gasoline with motor oil for cars, since it is not at all intended for such purposes. Compliance with the number of proportions, as well as the use of high-quality materials will extend the life of your tool for many years.

What happens if you pour working off into a chainsaw

When a chainsaw owner has been using it for a while, they may want to do some modification to the tool. And it’s good if his desires are limited to the purchase of various attachments that expand the functionality of the chainsaw. But some go further. they start experimenting with the gasoline and oil that their saw runs on.

If we have already spoken about gasoline earlier (most modern saws require it with a high octane number. at least 92-95), then it is worth mentioning the oil separately. Many car enthusiasts accumulate a significant amount of used engine oil during vehicle operation. And therefore, some have a desire to use this material for refueling a chainsaw.

If you do this, then it is guaranteed that the engine will fail. This is primarily due to the low lubricity of the recycled oil. It will burn with a lot of black soot. The metal particles contained in the oil will first clog the fuel filter (these are the larger particles), and then the cylinder O-rings will fail. A metal suspension in the oil will damage both the surface of the cylinders themselves and the bearings.

Some “innovators” try to use the working off to lubricate the chain itself and the block on which it is located. It also will not lead to anything good. What exactly will happen can be seen in the attached video.

Gasoline to chainsaw oil ratio

The proportions of oil and gasoline for refueling two-stroke engines of chainsaws of different brands is 40 to 1 or 50 to 1. This ratio is standard, which is used not only by beginners, but also by experienced sawers. It is this ratio for preparing the fuel mixture that is close to ideal, and provides lubrication of the rubbing parts of the crank mechanism and the piston.

How much oil should be poured into gasoline in milliliters? Calculated per ml, the proportion of oil and gasoline 1 to 50 is 20 ml per 1 liter. To prepare the correct mixture, you should fill 1 liter of gasoline in a plastic bottle and dilute it with 20 ml of oil. To correctly measure how much oil to pour, you should take a special measuring container and fill it up to the appropriate mark. If you plan to immediately prepare 2 liters of fuel, then 40 ml of lubricant must be added to this amount of gasoline.

There are other ratios that different manufacturers offer. These values ​​of the ratios differ insignificantly, but if you have subtracted other values ​​in the instrument’s passport, then you need to adhere to them. A value of 1 in 50 or 40 is standardized. Pour 15 ml of oil into 1 liter of fuel in the summer, and in winter, add at least 20-25 ml. Knowing the recipe for preparing the mixture, you should also figure out what kind of gasoline to pour into the chainsaw?
