What Oil to Dilute with Gasoline for Gasoline Saw

Chainsaw oil: which one to pour, in what ratio with gasoline, which one for the chains and which one for the stars

Gasoline and chainsaw engine and chain oils play one of the key roles for the stable operation of the tool. On their quality and properties depends the durability of the main working mechanisms of the saw, so the choice of fuel and lubricants should be taken with the utmost responsibility. Regular application of good-quality lubricants and fuel is the main guarantee of a long chain saw’s long life without unforeseen damages.

When choosing a suitable fuel, each owner of the tool should be guided by the brand and country of manufacture, available in the farm model. Old domestic-made saws called Ural and Druzhba are best fueled with AI-80 gasoline. It contains precisely those additives that are necessary for stable operation of the undemanding domestic engines. modern domestic models are designed to run on 92 gasoline.

The situation is a little different with imported chainsaws. Motors of all these models are designed for a more forgiving fuel, so the German, Swedish, American and Japanese chainsaws should be filled only with gasoline AI-92.

An important role in the choice of gasoline is its state. Many beginning gardeners are convinced that it is okay to fill the fuel reservoir of the saw with fuel that has been in the canister for an extended period of time. Some people believe that the tool is already working in conditions of constant dust, and that is why the carburetor manufacturers have provided a special air compensator, which is triggered when the air filter is worn.

This opinion is fundamentally mistaken. As a result of long stay in the canister gasoline loses its main properties, and its composition, depending on the material of the container, is filled with molecules of plastic or metal rust.

Because of long sitting in the canister gasoline begins to lose its vapor, which is exactly what ignites when you start the chainsaw. It is because of this that gardeners face a number of typical problems, which include:

To prevent this, you should regularly use only fresh fuel from proven gas stations. It is best to buy 2-3 liters of gasoline every morning before starting work in the garden. Using fresh gasoline will make it easier to start the chainsaw, and it will significantly extend its operating life.

Ratio of gasoline to oil for chainsaws

The proportions of oil and gasoline for filling two-stroke chainsaw engines of different brands are 40 to 1 or 50 to 1. This ratio is standard and is not only used by beginners, but also by experienced sawyers. This ratio for the preparation of the fuel mixture is close to the ideal, and provides lubrication of the rubbing parts of the crank mechanism and the piston.

How much oil to pour into gasoline in milliliters?? The ratio of oil and gasoline is 1 liter to 50, which is 20 ml to 1 liter. To obtain the right mixture, you need to fill a plastic bottle with 1 liter of gasoline and dilute it with 20 ml of oil. In order to measure correctly how much oil to use, it is necessary to take a special measuring jug, and fill it to the corresponding mark. If you plan to prepare 2 liters of fuel at once, you need to add 40 ml of lubricant to this amount of gasoline.

There are also other ratios offered by different manufacturers. These ratios differ slightly, but if you have read in the passport to the tool other values, it is required to adhere to them. Values of 1 to 50 or 40 are standardized. Add 15 ml of oil per liter of fuel in the summertime and at least 20-25 ml in the wintertime. Knowing the recipe for the preparation of the mixture, you should also understand the question of what gasoline to pour into the chainsaw?

Stricter criteria for choosing oil component. In the best case, it is the mineral or semi-synthetic engine oil recommended by the manufacturer, designed for use in high-speed two-stroke engines with air cooling.

Mineral oils have the advantage of lower cost. Their more expensive semi-synthetic and synthetic counterparts benefit from improved performance and conformity with environmental standards.

  • retain performance over a wide range of operating temperatures;
  • do not form soot deposits;
  • contain in their composition detergents, antioxidant, preservatives and other additives useful for the power unit.

The ratio of oil to gasoline for the fuel mixture

In order for a two-stroke chainsaw engine to work in the optimal mode for it, oil and gasoline must be mixed in certain proportions. These are usually listed in the tool’s instruction manual, as well as on grease packages. Let’s consider briefly what will happen if the recommended ratios are not complied with, or violated by mistake (ignorance).

If you add too little oil in gasoline, its concentration is not enough to effectively lubricate the rubbing parts. The engine will make a ringing sound, heat up excessively, and fail quickly. Too much oil is also bad, as the excess will not burn properly. This will lead to fouling of the cylinder walls and piston, contamination of the spark plug, the exhaust system. Also power will drop, fuel consumption will increase, and there will be excessive smokiness of the exhaust during operation.

To avoid these problems, oil and gasoline should be mixed in the proportions recommended by the manufacturer. They are specified as ratios. 1:50, 1:40, 1:25 and so on. Any of these proportions tells how much oil to pour per volume of fuel. For example, to prepare a 1:25 mixture, you would need 1 liter of oil to 25 liters of gasoline.

It is important not to confuse the two! Quite often the indicated ratios are perceived by users vice versa. For example, 1:50 is understood to mean 50 milliliters of oil for 1 liter of gasoline. It is a serious mistake that will lead to a higher concentration of oil in the fuel. This ratio actually only requires 20 milliliters of oil per liter.

How not to confuse the proportions? After all, few people need to prepare 50, or even 25 liters of fuel mixture for a chainsaw. Especially since gasoline mixed with oil can’t be stored for long. Usually make as much as you need for a day or two. And given the small gasoline consumption of a chainsaw, that’s 1-5 liters.

There are three ways to properly dilute gasoline for a chain saw in small volumes:

  • Divide 1000 by the second number in the proportion. For example, it is necessary to prepare a mixture in the ratio 1:40. Divide 1000 by 40, you get 25. This is how many milliliters of oil you pour into 1 liter of gasoline.
  • Solve the proportion, like at school. To do this, the required volume of gasoline in liters divided by the second figure in the proportion. As a result, we get the required volume of oil in liters. Convert liters to milliliters for convenience. Let’s say you need 3 liters of mixture in the ratio of 1:50. We solve this: 3/50 = 0.06 liters. To turn liters into millilitres, we transfer the comma to the right by three digits and we get 60 millilitres.
  • see table. This is the easiest, quickest and most obvious way if the proportions are standard. The other two methods are needed to understand why you need to pour 20 milliliters of oil per liter of gasoline, not 50, in the 1:50 ratio.

Now briefly about why the proportions vary from manufacturer to manufacturer and why there is no single standard. There are at least three reasons for this. First, different characteristics of oils and gasoline. Secondly, the quality of engine assembly (technology, materials) is also different. Third, the mode of operation of the tool. For example, for chain saws of some manufacturers it is recommended to add 20% more oil in the mix to run-in.

It is recommended to buy unleaded gasoline for the operation of garden equipment. Otherwise there is a risk of engine failure. The manufacturers advise fuel with an octane number not lower than AI-90, better yet AI-92 or AI-95. For individual recommendations for your tool, see the manual. At the gas station, pour the right amount of fuel into the canister. Preferably take a metal oil: in such a container no static electricity from friction is generated, which increases the safety of use.

Buy brand name oils for two-stroke engines, preferably API-TB or API-TC. The manufacturer should state the recommended brands in the owner’s manual. Also consider their composition. Mineral oils are suitable for use in warm weather. Synthetics are better, they are less viscous and can be used even in freezing temperatures. Semi-synthetic oils are mineral oils with improved qualities, versatile for any season. Refer to the package for the operating temperature limit. Also note the volume. It is not the proportion of gasoline and chain saw oil that matters, but how much fuel mixture you need for one filling and how often you will be working with the tool. If you have a grass trimmer or chain saw in your arsenal and use one or the other tool several times a week, it makes sense to buy a large 3 to 5 liter canister of oil. For several mowing operations during the gardening season, a 1 liter bottle is enough.

Mixing oil with petrol

When you start working with a tool, the question always arises how much oil to add to gasoline for a chainsaw or grass trimmer. It is important to remember that for two-stroke engines the ratio is 1:50, t.е. 100 ml of oil per 5 liters of fuel. Why it is important to follow the proportions? The gasoline is an excellent fuel that can burn the pistons and spark plugs, and the lack of oil reduces the lubricating power of the fuel mixture, which leads to burrs in the piston group and increases the risk of engine damage.

The easiest way to follow the proportions of gasoline and chainsaw oil is to use measuring containers. They are marked with a scale that is easy to follow. Before pouring in your gasoline and oil, make sure the container is clean. Avoid getting any water or dirt in your system. it could affect the quality of the fuel mixture. Pour gasoline up to the proper level first, then add oil. also up to the proper level. Tilt the container several times to mix it. The liquids will mix quickly and the mixture will become homogenous in color, e.g. green or red (depending on the composition of the oil).

It is important to know! Never use plastic drink bottles for storing and mixing the fuel mixture. Gasoline corrodes plastic. And even if the walls of the bottle look intact, harmful components will enter the fuel mixture and with it the engine. This is very bad for the carburetor.

Wearing gloves is recommended to protect hands from the oil and gasoline. Also do not forget about the elementary rules of fire safety. Mix the liquids outside so that gasoline fumes do not build up indoors. Do not smoke while working and exclude other factors that can cause inflammation of flammable materials and lubricants.

Pour the prepared fuel mixture into the fuel tank and close the cap tightly. If you make more mix than you can use at one time, empty it into a separate canister for storage or leave it in the mixing tank. Just make sure you close the cap tightly. The ready mixture can be stored for two weeks and used for refueling without risk to the engine. The only condition is that you do not leave it in the tank. If you will not be using the tool for an extended period of time, use up all the leftovers or drain them off.

Now you know how to dilute gasoline for a chainsaw so as not to harm the engine. Try to do this on your own. after you prepare the fuel mixture several times, you will know how many components are needed so there is no excess mixture. You can buy everything you need in our online store. With brand-name oils your tool will last a long time.

Petrol to oil ratio for chain saws

The oil to gasoline ratio for filling two-stroke engines of different brands of chainsaws is 40 to 1. This ratio is standard and is not only used by beginners, but also by experienced chain saw operators. This ratio for preparing the fuel mixture is close to ideal and ensures the lubrication of the rubbing parts of the crank mechanism and the piston.

Ratios for the fuel mixture

This is interesting! Before mixing petroleum products, you should consider external factors. If the chainsaw is new, it requires a running-in period, and for this you need to add 20% more oil to the fuel than the standard values. You also need to add 20% more lubricant if you work with tools at low temperatures.

How much oil to put in gasoline in milliliters? The ratio of oil and gasoline is 1:50 per ml, which is 20 ml per liter. In order to prepare the right mixture, you should fill a plastic bottle with 1 liter of petrol and dilute it with 20 ml of oil. In order to correctly measure how much oil to pour, you should take a special measuring container, and fill it to the appropriate mark. If 2 liters of fuel are to be prepared at once, 40 ml of lubricant must be added to this amount of gasoline.

There are also other ratios offered by different manufacturers. These ratio values differ slightly, but if you have read in the passport to the tool other values, then it is required to stick to them and. Value 1 to are standardized. Fill 1 liter of fuel with 15 ml of oil in the summer, and in winter, fill not less than 20-25 ml. Knowing the recipe for the mixture, you should also understand the question of what gasoline to fill a chainsaw?

What kind of gas to put in your chainsaw?

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, it is forbidden to use pure gasoline for the saw. Saws are filled with fuel mix made of fuel and oil. Standards for refueling chainsaws of different models are regulated by the manufacturer.

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

Domestic saws work on fuel AI-80. Foreign modifications need AI-92 gasoline. It often happens that the instructions indicate the brand of fuel AI-95. But experts say that gasoline AI-95, which is produced in. does not meet the quality standard. This fuel contains a lot of anti-detonation additives.

This gasoline may only be used in a chain saw mixture 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. It is therefore not recommended to refuel with 95 degrees Celsius.

Working ratio of the fuel mixture

Standard petrol to oil ratio in the fuel mix for different models of carburetor chainsaw engines is 40:1 and 50:1. Such ratio provides proper lubrication of friction parts of the crank mechanism and piston group and does not prevent complete combustion of the gasoline-air mixture.

With external factors, the fuel mixture can be adjusted to increase the amount of oil. Such a need arises during the running-in phase of a new tool, as well as in case of high air temperatures. In this case the standard dosage of oil is increased by 20%.

In practice it is used to increase the percentage of oil in the fuel mixture, if its characteristics do not fully meet the stated requirements. How much oil per liter of gasoline is needed in each case is up to the sawyer.

Break-in period for new machines

This concept includes a gentle mode of operation of the chainsaw at the initial stage of its operation. The technology also provides for the work of the engine on a mixture with 20% more engine oil.

The running-in time in engine hours is specified in the enclosed instruction manual. In practice it is enough to fill 3-5 times the gasoline tank of the saw in order to reach the working level.

New models don’t need a running-in period, but it is not recommended to use the chain saw with heavy loads for the first hours.
