The ratio of gasoline and oil for a Ural chainsaw

We found a domestic Ural chainsaw in the garage. My husband took it apart, cleaned it, says it’s like new and should work. What kind of oil to pour into the Urals to try to turn it on. What kind of gasoline will this chainsaw work optimally on?

The Ural chainsaw is considered a descendant of the Druzhba chainsaw - a reliable and worthy unit. If adjusted well and used regularly, such a saw almost always shows stable operation.

As for gasoline, previously AI-76 grade was poured into such a chainsaw, but now A-80 can be poured. As for oil, you can use domestic M8-B or any other imported oil for a two-stroke engine. Oil should be added to gasoline in a ratio of 1:25.

First of all, read the operating instructions for your domestic chainsaw.

What kind of oil and in what proportions, a whole chapter of instructions is devoted to this topic.

You write about the Ural chainsaw; the best option would be Avtol (this is M-8B motor oil).

If you mean oil for preparing a fuel mixture for a chainsaw, then the proportions are 1:20 (oil to gasoline).

The same oil can also be poured into the chainsaw gearbox.

Since the Ural chainsaw is a descendant of the Soviet Druzhba chainsaw, and Avtol (M8-B oil) was popular during the Soviet Union (recommended for use in GAZ, ZIL, etc. cars, including Ural ), then it is considered the best option for such a chainsaw, plus, the price is completely affordable.

When purchasing oil, pay attention to the labeling; GOST must be indicated there.

GOST for this oil is GOST 10541-78.

M-12TPU, MGD-14M, etc. oils are also suitable, these are all domestic oils, you can also use imported ones, but domestic ones are better.

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 advice and recommendations. Repairing the Ural chainsaw has already been discussed earlier. The problems were a clogged air filter and adjusting the chainsaw jets.

Little attention was paid to the correct preparation of fuel for a chainsaw, since it can also cause breakdowns or problems in the operation of this gas-powered tool.

It is better to use the oil for chainsaws that is recommended by the manufacturer. First of all, this is 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 a chainsaw should be approximately 1:25. But this value is true only for chainsaws of a domestic manufacturer and the AI-76 gasoline used for their operation.

Proportion of oil and gasoline for a chainsaw

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

To use foreign chainsaws, as a rule, gasoline of no lower than 92-95 grade is used. 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 must act at your own peril and risk, since it is not recommended to use it for chain lubrication due to rapid oxidation.

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

To refuel a chainsaw, you should use only oil that meets all the requirements and operating conditions of a two-stroke engine. Only in this case there will be no need to repair the Taiga chainsaw or any other.

What kind of gasoline

must be poured into the chainsaw

Hello! I am glad to see you again, dear readers and subscribers of Andrey Noak’s Blog. Anyone who has a chainsaw at home already knows exactly what kind of gasoline and how to fill

. But anyone who just wants to buy such a unit will find the article interesting.

A chainsaw is one of the most convenient and versatile household units. Before use, you need to prepare the fuel mixture. But in order for the unit to work correctly, you must follow all the manufacturer’s recommendations. Each model is individual, so what kind of gasoline to fill

into a chainsaw?

Under the brand

For modern brands, for example, Husqvarna, Partner, Makita, Echo, Shtil, AI-92 gasoline is suitable. Today, a huge number of people complain about premature failure of chainsaws due to bad gasoline. Therefore, some experts recommend pouring AI-95 into such chainsaws. At the same time, a good AI-95 can “burn the piston,” and again a certain number of people

found a compromise and mixed AI-95 with AI-92. In general, it all depends on the quality of gasoline and ultimately it’s up to you to decide.

For domestic instruments, Ural

, Friendship, it is recommended to take AI-80 gasoline. It is very important that fuel consumption is minimal.

Making the mixture: important proportions

When using a two-stroke engine, clean fuel is purchased separately and mixed with oil, often in proportions of 1:50. It is structurally impossible to install an oil pump in such an engine, so pouring pure gasoline into the chainsaw is strictly prohibited! The manufacturer indicates the proportions, quantities and some brands in the operating instructions.

Important points during the cooking process:

Domestic chainsaws work with oil M8-V, M-12TPU, M8-V, TP, MGD-14M. In some cases, foreign options can be used;
Proportions: 2.5 liters of FI-80 gasoline per 100 grams of oil;
Foreign models are characterized by minimal fuel consumption. They work on foreign oils, and their proportions are 1:40 or 1:50.

Fuel mixture

To properly prepare fuel, you will need a list of additional tools:

Plastic or metal container for diluting the substance;
Measuring bottle for gasoline;
Dispenser;
Syringe;
Watering can for filling the tank of a chainsaw.

Some manufacturers, such as Stihl, immediately make measuring containers for more convenient measurement of the fuel mixture .

Different manufacturers produce oils in different shades. The manufacturer HP produces a red liquid. Green oil is in the premium “synthetic” segment. For a Husqvarna chainsaw you need to take the appropriate brand of oil. It is of high cost, good quality and has a green or blue color.

The main thing is to correctly calculate the proportions of the mixture. Excess oil can form carbon deposits on pistons and spark plugs. Excess gasoline can cause engine damage or piston scuffing. Each manufacturer gives its own proportions for models of different power.

To mix the components, you will need the above additional accessories. Also on sale you can find special canisters with two holes for oil and gasoline. Everything is very simple here, pour in the ingredients, screw on the lid tightly and mix by tilting the container. You can use glass and plastic bottles.

No water or dust should get into the fuel mixture

Good to know

Fuel must be prepared for 3 refills. After all, storing a large amount of fuel can negatively affect the operation of the chainsaw. The mixture can behave differently, because it will be influenced by many factors. As a result, your household unit may suffer serious damage, which will entail financial costs.

Sometimes even the container can affect the quality of the liquid. Plastic and glass react with gasoline, creating a flash fire hazard.

It is important to remember that if the chainsaw breaks down due to poor-quality or incorrect mixture, it will not be possible to repair the unit under warranty.

The finished liquid cannot be stored for more than a month, because the oxidation process occurs. After working with a chainsaw, you need to use up the remaining fuel, turn off the engine and remove the remaining fuel mixture.

Fuel consumption

One of the most important questions that arises among owners of saw tools, because everyone wants to know what to expect.

The volume of almost all tanks is approximately 500 ml. If the power of the chainsaw is 2 kW, then the consumption of the fuel mixture will be approximately 1.2 liters per hour of operation. To put it simply, such a tool will be able to work at maximum speed for half an hour without a break. If the chainsaw is not so powerful, then its tank volume will be smaller. This way the user can independently control fuel consumption.

READ How to Clean a Shtil Chainsaw

Over time, the user will learn to service his tool without any help. The main task will be to maintain the economic unit in good working condition, using high-quality fuel mixtures. Follow safety rules when preparing flammable liquids. This will help preserve the instrument and not harm yourself and the environment.

Helpful Tips:

Sometimes it's better to add a little oil than to regret it. If you give a little more oil than indicated in the instructions, then nothing bad will happen. The formation of carbon deposits is possible in cases of a large amount of oil and if the specified proportions are not observed;
It is better to store the finished mixture for a month and no more, because for some reason it will lose its quality;
Proper completion of work. Be sure to use or drain the contents of the tank, this way you can extend the life of the rubber and plastic seals;
You should not use oil intended for mopeds for a chainsaw, because it is designed for low speeds.

The correct operation of your equipment depends entirely on you. Firstly, do not disdain the manufacturers' instructions or, at least, the instructions on the oil packaging. This will help avoid unpleasant situations. The neighbor does not always know what is best to do. The cheapness of oil and gasoline is not an indicator of high quality, because tool failure can cost much more (about 80% of the cost of a chainsaw) than what is saved on the fuel mixture

facilities.

What are the characteristics of a chainsaw?

If you have a dacha or a rural house, you need a chainsaw. How to dilute gasoline for a chainsaw? For gardening needs, a household chainsaw is completely sufficient. Its power is small, but it is completely sufficient for removing old tree branches, cutting firewood and boards. This saw does not have a very huge weight and size. If you need to cut down trees on your property or are planning construction work, it is better to purchase a semi-professional chainsaw. Its operating period should not exceed 8 hours per day. The professional chainsaw has the highest power and can work for up to 16 hours at a time. Durable materials are used to produce such saws, and implementation requires certain abilities. Professional chainsaws are used for felling wood on an industrial scale and for other similar work.

All of these types of saws vary in both power and weight. If you are not planning large permanent work, it is better to limit yourself to a household chainsaw, which weighs much less and is therefore easier to handle. Professional saws, on the contrary, have a power of up to 6 kW and, accordingly, enormous weight. How to dilute gasoline for a chainsaw? Choice of oil. The choice of such a saw depends on the thickness and strength of the material being cut.

Why is oil in a saw important?

It doesn’t matter which chainsaw is powered by a gasoline engine. how to dilute gasoline with dilute gasoline for a chainsaw. How to pour gasoline into a chainsaw 1. How to dilute gasoline for where to buy spare parts for how to dilute gasoline for a chainsaw?. Chainsaws use a two-stroke engine, and the role of the gearbox is played by a single-stage chain transmission that drives the chain. In two-stroke engines, the gasoline-oil mixture is poured directly into the tank. To make a gasoline-oil mixture, use gasoline with an octane rating of 90 or higher. In our criteria, this is A92 or AI92 gasoline. It is better not to use 95, because it can be produced from 92 using additives and will lose its characteristics after some time. Gasoline must be used as fresh as possible, as it polymerizes over time, especially in the light. As a result, carbon deposits appear in the combustion chamber.

In what proportions should the liquids be mixed?

The proportions of gasoline-oil consistency for each brand of saw are determined by the manufacturer. How to dilute gasoline for (Ural, friendship, what oil to use for a chainsaw, how to dilute gasoline for a chainsaw? Gasoline with a high octane number is used as fuel for a chainsaw: ai-92 or ai-95. The more common proportion is 1:50, the best for saws with a power above 1.5 kW. But some manufacturers may focus on other proportions: Chinese - 1:25, Partner - 1:40. For chainsaws with a power of less than 1.5 kW, Stihl and Husqvarna companies recommend a ratio of 25 ml of oil per 1 liter of gasoline .

Making the mixture: important proportions

Important points during the cooking process:

Domestic chainsaws work with oil M8-V, M-12TPU, M8-V, TP, MGD-14M. In some cases, foreign options can be used;
Proportions: 2.5 liters of FI-80 gasoline per 100 grams of oil;

Maximum power crankshaft rotation speed, rpm 6200 ±200

Fuel consumption at maximum power mode, g/kW.h. (g/l s.h), no more than 632 (465)

Carburetor adjustment

Adjusting the idle speed of the chainsaw engine.

The adjustment is made by changing the quality and quantity of the combustible mixture entering the engine cylinder. The amount of mixture is changed by screw 3 (Figure 1), which limits the rotation of the throttle valve control lever 1 towards its closing. The quality of the mixture is changed with screw 1 (Figure 2) of the carburetor. When adjusting engine idle speed, you should be guided by the following requirements:

a) The engine should idle steadily and the saw chain should not move along the bar.

b) There should be no strong smoke when the engine is running.

c) The engine should have good throttle response, that is, when the throttle control lever is pressed sharply, it should quickly gain speed.

d) It is recommended to adjust the idle speed in the following sequence: - start the engine and warm it up at low and medium speeds. Use screw 3 (Figure 1) to set the minimum stable speed at which the saw chain does not move along the bar. If the engine smokes heavily (a sign of an excessively rich mixture), then partially tighten screw 1 of the carburetor. At the same time, the engine speed will increase and the exhaust smoke will decrease; — after this, you should again set the minimum, stable engine speed by partially unscrewing screw 3 (Figure 1); — after this adjustment, it is necessary to check the engine response. To do this, sharply press the throttle control lever for 2-3 seconds until it stops. In this case, the engine should quickly gain momentum. If the engine stalls or has a “drop” in power, that is, it slowly picks up speed (lean mixture), then it is necessary to partially unscrew screw 1 of the carburetor. Engine speed will decrease. To increase the idle speed, screw 3 must be partially tightened. Check engine response again; — upon completion of the adjustment, secure screw 3 with locknuts 2 (Figure 1).

4.5.2 Adjusting the engine for maximum power

This adjustment should be made after a 25-hour run-in of the chainsaw in operation and after adjusting the engine idle speed. The adjustment is made with screw 2 (Figure 2) of the carburetor, by making the combustible mixture leaner or richer at engine operating mode. When the screw is partially screwed in, the mixture becomes lean; when unscrewed, it becomes richer. The most advantageous position of the carburetor screw 2 is determined experimentally by checking the operation of the chainsaw when sawing wood. In this case, you should be guided by the following requirements for the operation of a chainsaw.

Petrol

Gasoline comes with an octane number no less than AI92. There is an option to also fill in AI95, alas, its quality at our gas stations is not civilized enough, if you do not know how to use 95, then it is still better to take AI92 gasoline to dilute gasoline in a chainsaw. It also makes no sense to take gasoline that has been sitting for a long time in a canister, tank or other container. Gasoline for making fuel into a chainsaw must be fresh, otherwise it loses its characteristics, namely the octane number, and if you run the chainsaw on such fuel, it will not produce a workable version of power. And the saddest thing in this case is that the failure of a chainsaw due to poor fuel is considered a non-warranty case and leads to expensive repairs. Sometimes it's easier to buy a new chainsaw than to repair it after a breakdown!

Oil

According to the classification of the American Petroleum Institute (API), the South American Petroleum Institute, oil for 2-stroke engines is classified as API-TB, in addition there are oils of the API-TC class, unfortunately they are designed to work with less load than most of our common chainsaws. If you take the power class according to the systematization of the Japan Automobile Standards Organization (JASO), then focus on the JASO- and JASO FD classes (see Table 1 below.). Do not under any circumstances use oils for four-stroke engines! Remember that in a two-stroke engine the oil must burn one hundred percent, which means it is better to take synthetic oil, as it produces less smoke and combustion residues. If you fill your chainsaw with oil for four-stroke engines, which will not burn completely and carbon deposits will appear upon completion, then your CPG will fail. The best thing to guide you when choosing oil for a chainsaw is the instructions for it.

Good to know

Sometimes even the container can affect the quality of the liquid. Plastic and glass react with gasoline, creating a flash fire hazard.

It is important to remember that if the chainsaw breaks down due to poor-quality or incorrect mixture, it will not be possible to repair the unit under warranty.

Proportions

When preparing a fuel mixture of gasoline and chainsaw oil, be sure to check the manufacturer's recommendations. Why is it so important to follow these recommended proportions? If the amount of oil in gasoline is small, the cylinder and piston will heat up and, accordingly, scuffing will occur, which means failure of the CPG and repair. If there is a lot of oil in gasoline, then this is carbon deposits and again failure. Each manufacturer has its own recommendations on proportions (see Table 2 below). Try not to store the finished mixture for more than a month. Do not store it in direct sunlight or open. Avoid ingress of water and dust - this will lead to carburetor failure, since the fuel filter is often not able to completely clean the fuel.
