Proportion of oil gasoline for 2 chain saws

Aspects of the device and how to fuel the saw

Now we are going to “dive” into the very core of this tool, so that you have at least a general idea of what your “helper” consists of. In fact, this kind of tool can responsibly be attributed to the mechanisms of the classical direction, which work through the involvement of the internal combustion engine.

It is no exaggeration to say that this type of tool is the easiest of all other machines, because it has no gearbox and is powered by a regular two-stroke engine with one cylinder and working on gasoline.

The main advantage of a chainsaw is that it is arranged quite simply, which contributes to greater reliability, as well as failure-free operation in difficult and demanding conditions. Next, let’s look at the construction of the saw in more detail, so:

  • engine;
  • clutch;
  • ignition system;
  • carburetor (cf. carburetor adjustment);
  • fuel system;
  • the air cleaning system;
  • starter;
  • A chain (see “chain” on page 56) is better for woodworking. how to sharpen a chain);
  • tire;
  • chain brake;
  • chain tensioning mechanism;
  • chain lubrication system (see gasoline and benzene). oil for chain lubrication).

In essence, the device is understood, but now the important issue is the lubrication of chain saw parts. Many people don’t understand why they need it at all? The answer is simple enough; like all mechanisms, a chainsaw, especially its individual parts, requires special care, including periodic lubrication.

It is necessary that your tool will serve you for many years, as during the operation of gasoline saw parts make the movement, which should be smooth, smooth, so as not to damage nearby parts.

So, as everyone knows that the friction force breaks the surface, and here, if you do not lubricate the chainsaw as needed, the parts will simply wear out quickly and the tool will be out of LADA. You need it? I don’t think so. So you need to take care of your chainsaw so that it “has the strength” to serve you for many years.

When choosing a chainsaw, you should be guided by your needs, what you want to use it for.

If you have to take it in a similar way, then choose a mini chainsaw.

For sawing is better suited to sawmills with circular saw blades.

ECHO Pro-Tip: Mixing Fuel and Oil for Power Tools

Gasoline and chain saw oil. which is better?

Often beginners ask, but what is the best to take gasoline for their tool? In order not to make a wrong choice, it is recommended to read the instruction manual of the tool. In the manual, each manufacturer specifies the correct grade of fuel. If the engine manufacturer specifies that the octane rating should not be lower than 95, it is not recommended to fill the tank with 92 gasoline.

Now let’s understand what oil is better to take for chainsaw engines. Special oils are used for this purpose. It is forbidden to take engine oils of car engines for the preparation of the fuel mixture. For chain saws you need to buy lubricant for two-stroke motors, which are on sale not only in specialized centers, but also in online stores.

Good to know! It is necessary to distinguish that manufacturers produce two types of lubricants for chainsaws. for chains and engines. Chain oils are poured into a separate tank of the tool, and they are used to lubricate the chain while the chainsaw is in operation.

Engine oils for two-stroke motors are produced by such manufacturers

Usually the ratio is indicated on the bottle with the lubricant, so it will be difficult even for beginners to get confused with the preparation of the fuel mixture. Under no circumstances should you use waste even as a chain lubricant. This will result in the tool needing to be repaired as soon as possible.

How to fill up your chainsaw

How to correctly fuel a chain saw to make it work for you a long time and not cause repair problems. This question is often asked by those, who have recently bought a chainsaw and had no experience in mixing fuels before. Usually the instructions for a particular chainsaw have instructions from the manufacturer. Based on the recommendations of various manufacturers we have compiled a short manual.

In order to dilute oil with gasoline for a chainsaw you must use only high quality components. Gasoline needs to be 92 or 95 octane and without ethyl or other additives. Gasoline should be fresh and not impaired.

99% of chainsaws are built with two-stroke engines and thus the oil should be for 2T engines. The best is considered synthetic oil from reputable manufacturers. Some gasoline tool manufacturers produce their own oil for their equipment. For example Sturm, Spektr and others. Never skimp on oil in terms of quality. over, its flow is not great. Now about consumption.

How to dilute gasoline with oil fuel mixture for chainsaws and trimmers mineral or synthetic

How to dilute petrol with chain saw oil in the right proportion. General proportions for all gasoline chainsaws are from 20 ml to 50 ml of oil per liter of gasoline (depending on the manufacturer) For most home chainsaws dilute oil with gasoline at the rate of 25 ml per liter of gasoline. For exact gasoline proportions, however, consult the recommendations for your particular saw. What will happen if the oil is less than normal?? Deteriorate the lubrication of the engine and accelerate its failure. If you add more oil, your chain saw smokes and causes soot on the piston and plug.

How to measure oil? When you purchase a chainsaw, it usually comes with a plastic measuring jug with divisions. It is usually not very accurate and the measuring stick is not to be trusted. Many people use a medical syringe to accurately dispense oil and this is not a bad option. Pour gasoline into a canister or glass jar first, and then add oil to it for better blending. Stir well and thoroughly. Prepare the mixture on the basis of its production within 10 days. After 10 days, the fuel mixture that is not used loses its qualities and will ruin your tool when you use it. After use, be sure to drain the remaining gasoline from the tank into a mixing tank until the next time you use the chainsaw. Remember to keep the fuel mixture tightly sealed and stored away from sources of fire and heat.

After you’ve finished the job and drained the gasoline from the tank and you’re not going to use the tool in the near future, you need to start the chainsaw again and let it run until it stalls. This is to keep the carburetor dry during storage.

Remember that most chain saw engines failures occur as a result of using inadequate or improperly prepared fuel and lubricants. Chainsaw engine repair or replacement is sometimes the price of an almost new tool, and the warranty repair for the breakdown as a consequence does not apply. Your dealer or service center can pinpoint the cause of a faulty engine. Therefore, take seriously the preparation and selection of a quality fuel mixture for your tool.

How to dilute gasoline for a chainsaw? Oil selection, proportions

One of the most frequent questions users ask is: How to dilute gasoline for a chainsaw?? When preparing the fuel mixture, the following factors must be taken into account:

What mix oil to use! What ratio should I run in different saws!

  • The quality of gasoline, its octane rating
  • Type of oil for two-stroke engines
  • Mixing ratio
  • Devices for the convenience of gasoline dilution

How you prepare the mixture for the saw is how it “buzzes”. All about proportions of oil and gasoline

You can use different chainsaws in the work. for three or four thousand, bought in a hypermarket at a discount, or for 15-20. from an official dealer. Their quality, performance and service life will be different. But there is one component, without which it is impossible to use this tool at all. Without a properly made fuel mixture. Seemingly simple instructions turn out to be not so unambiguous in reality, and an incorrectly prepared mixture can cause unfortunate consequences.

What kind of gasoline to put in your chain saw?

Let’s find out what kind of fuel is recommended for this type of device. As there is a 2t (two-stroke) motor on chainsaws and it is impossible to put an oil pump on it, then it is forbidden to use pure gasoline for the saw. Saws are filled with fuel mixture of fuel and oil. Filling rates for chain saws of different models are regulated by the manufacturer.

Let’s consider what kind of gasoline to pour into a chainsaw is advised by experts. Filling gasoline saw is carried out with fuel with an octane number of more than 92. To create a mixture you cannot use fuel with expired shelf life, made from condensate, which includes water and various impurities.

Domestic saws work on AI-80 fuel. Foreign modifications require AI-92 gasoline. It often happens that the manual indicates the brand of fuel AI-95. But experts believe that gasoline AI-95, which is produced in. does not meet the quality standard. This fuel contains many anti-detonation additives.

Such gasoline for chainsaws may be used only if it is of high quality. The complexity of the application lies in the use of additives, with which manufacturers increase the performance of fuel that has a lower octane number. That is why it is not recommended to use 95 gasoline.

What oil to use for chainsaw chain?

To know exactly what chain oil to use for chainsaw chain lubrication, you need to study the instructions of its manufacturer. Almost all tool companies recommend pouring a product that stands out with the highest adhesive properties. This means that the material used to lubricate the chain must have adhesion to the metal surfaces of the chain and tire.

proportion, gasoline, chain, saws

We need to understand why the lubricant has adhesive properties. While the chain is running on the bar, the saw unit is running at high speed. If a chainsaw chain oil with low adhesion is used for lubrication purposes, more than half of the fluid will inertia fly off the bar top and never reach the bar bottom. As a result, such oil will prove ineffective, and the tire and the chain will fail rather quickly because of the constant friction.

What gasoline to fill in a chainsaw?

According to experts, you should use unleaded gasoline, obtained by adding lead-free additives, the octane number of which exceeds 90. Foreign models require higher brands of gasoline and use branded oils from tool manufacturers. The perfect fuel is AI-92 grade. How to Mix Gasoline for STIHL 180 Series Chainsaws? in this case oils in 1:40 mixture are implied. It is quite suitable for it and fuel AI-95, but according to professionals it is better for chainsaws do not use.

The thing is that it is produced on the basis of AI-92 with the use of certain additives, which change the quality of the fuel. These components are deposited on the inner parts of the tool and when they reach a critical mass, they begin to flake off, disrupting the operation of the mechanism. The best option is to follow the instructions that came with the selected model. Use fresh gasoline is recommended, because storing it in containers for too long loses its octane properties.

Third: Use quality oil

Use the two-stroke oil recommended in the owner’s manual or its full equivalent. Air-cooled two-stroke internal combustion engines mounted on garden equipment differ from boat and motorcycle engines in terms of engine temperature, rpm. That is why two-stroke oil for garden equipment, chainsaws, chainsaws differs from oil for boat engines and motorcycles. It is also important to know that two-stroke oils are often counterfeited, so try to buy oil only from dealerships. Two-stroke oil, in a closed container and under normal conditions, can be stored for years, the exact period of storage is indicated on the packaging.


The main component in the fuel mix for chainsaw engines is gasoline with an octane rating of at least 92. Expired storage, gas condensate-based, with water and mechanical impurities in its volume, is not suitable for the preparation of fuel.

  • Opinions of experts on the use of different brands of gasoline are mixed. On the one hand it is recognized that domestic A-92 gasoline does not fully comply with the European standards.
  • On the other hand the quality of gasoline A-95 is questioned because of the high content of anti-detonation additives. Use this fuel to make gasoline for a chainsaw only if you are absolutely certain of its quality.
  • The difficulty lies in the presence of various improving additives, which unscrupulous manufacturers and retailers use to increase the performance of automobile gasoline with a lower octane rating.

There are also irreversible changes in the operating properties of fuel when it is stored for a long enough time in plastic containers, regardless of its level of gasoline and oil resistance.

Advantages of branded oils

The oil to gasoline ratio for a chainsaw is not the main factor influencing the stable operation of the equipment. Oil quality is very important, because it will determine to what extent all the elements of the engine system will be lubricated.

It is recommended that you purchase fluids from brand names. Only two-stroke oils should be chosen. It is forbidden to use for dilution of fuel and lubricants for car engines.

Brand names including Husqvarna, Kreissman, STIHL and Sadko have many advantages, which include:

  • economical consumption;
  • No fouling;
  • Reducing the toxicity of exhaust gases;
  • stable performance under the most demanding conditions.

However, the main advantage is a long service life.

How long can you store a diluted prepared mixture

The standard shelf life of a prepared oil and gasoline mixture is one month. It is not recommended by chainsaw manufacturers to mix large amounts of fuel in the instruction manual. The best option is to prepare the mixture for work and full production, and then refill the fuel if necessary.

It is undesirable to store the fuel mixture in the gasoline tank for more than two-three weeks. When not using the tool, it is recommended to drain the fuel and dry the tank.
