How To Thin Saw Gasoline

What will happen if you pour working off into a chainsaw

When the owner of the chainsaw 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 talked 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.

The surest solution is to follow the recommendations specified in the instructions for the product! In the absence of such an opportunity, you can use a special fuel preparation formula.

Gasoline and oil for chainsaws. which is better

Often beginners ask, which one is better to take gasoline for their instrument? In order not to make a mistake in the choice, it is recommended that you read the instructions for the tool. In the instructions, each manufacturer indicates the corresponding brand of fuel. If the manufacturer indicates that the octane number should not be lower than 95, then it is not recommended to pour 92 gasoline.

Motor oils for two-stroke engines are produced by the following manufacturers:

Usually, the ratio is indicated on the lubricant bottle, so it will be difficult even for beginners to get confused with the preparation of the fuel mixture. Do not under any pretext use working off even as a chain lubricant. This will lead to the fact that soon it will be necessary to repair the tool.

Why is gasoline mixed with oil for refueling chainsaws

It is necessary to dilute gasoline with oil in order to avoid the failure of the internal combustion engine. The reason for this is the design features of the lubrication system for two-stroke motors. In the design of such engines there is no chamber for filling engine oil, and if you fill in fuel without lubricant, then the crankshaft, piston, bearings and connecting rods will not receive lubrication. This will significantly reduce the service life of all the listed parts, therefore, it is prohibited to fill in clean fuel.

Gasoline and oil for the chainsaw must be poured in the appropriate proportions, which makes it possible to effectively lubricate the rubbing parts. Lack of lubricant or its excess will lead to negative consequences in the form of carbon deposits. In order for the tool to work properly, from the first day of operation of the tool, it is necessary to fill it not only with high-quality materials, but also observe the correct proportions.

For the engine to work properly, the main thing is to fill it with clean fuel without contamination.

Storage

It is recommended to dilute the fuel in a small amount without excess. It is impossible to store such a mixture for a long time (the properties of gasoline are lost), up to a maximum of 25-30 days. At the end of the work, it will not be superfluous to drain the remaining fuel and work out its resource at idle speed. This is due to the fact that storing the mixture in the product tank increases the wear of the seals.

Remember, the use of high-quality fuel and compliance with the manufacturer’s recommendations guarantees a long and fruitful operation of the product.

Chainsaws of different companies are based on a two-stroke internal combustion engine that drives the cutting headset of the tool. To drive the internal combustion engine, the proportions of gasoline with chainsaw oil are used. Combining gasoline with oil is a mandatory procedure, so if you just bought a tool, then you need to understand the peculiarities of refueling it.

Formula

  • High quality fuels and lubricants;
  • Correct proportions;
  • Mixing tools and technology.

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 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 put 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?

Proportions

There are several options for the ratio of fuel and lubricant. As a rule, this number ranges from 20 to 50 ml of oil per 1 liter of gasoline.

Again, you must follow the instructions for the product or the recommendations indicated on the oil label (priority of the instruction). In the absence of such, before diluting gasoline, you need to pay attention to the power indicator of the product, since the created proportion directly depends on it.

For chainsaws with power:

  • Up to 1.5 kW, the recommended ratio is 25 ml of oil per 1 liter of gasoline;
  • Above 1.5 kW 20ml / l.

In gasoline for a chainsaw, it is allowed to add oil a little more than the recommended proportions (up to 5 ml per 1 liter). In this case, you should be extremely careful, because non-compliance with the proportions can lead to breakdown, and as a result, expensive repairs.

If gasoline is diluted with a large volume of oil, then during operation the number of shock loads on the cylinder-piston system will be increased, and carbon deposits may also form, as a result of which the CHP will fail.

Adding a small amount of oil to gasoline for a chainsaw can lead to insufficient lubrication of the surfaces of moving elements, which will lead to additional friction of the elements and their heating, followed by the destruction of the entire mechanism.

and about gasoline

To say that in oil-producing and refining Russia gasoline is mostly of poor quality is to repeat the obvious. You can “get” to bad fuel not only at nameless gas stations, but also at large filling complexes with a big name. High-quality gasoline is very important for modern high-tech chainsaws. it allows them to work with maximum efficiency and minimum wear. The general requirement today is to use gasoline with an octane rating of at least 92. It has optimal performance for chainsaws.

The old Soviet units could be filled with 76th gasoline. Today it is not worth doing this even with cheap Chinese saws. you will only hasten her “death”. It is also not recommended to go to the other extreme. to pour the 95th or even the 98th into an expensive instrument, thinking that it will be better for him.

We recommend pouring 92nd gasoline, purchased from trusted places, into two-stroke engines, of which you have no doubt. Buyers come and ask: the better the gasoline, the better the saw? Why then not pour the 95th? After all, more advanced cars only require it.

Answer: most of Russian gasoline 95 is the same 92nd, but with additives that reduce detonation. Chainsaw this parameter is not important, it needs the purest gasoline, since the additives are completely unnecessary. Therefore, the logic is simple: a pure 92nd is better than the more expensive 95th, but with unnecessary additives.

How to dilute gasoline with chainsaw oil?

To prepare a mixture of gasoline and oil, the gardener will need a small container, a measuring cup, and a watering can. As a rule, manufacturers of garden equipment complete their chainsaws with branded cans or cans, made mainly of plastic. However, it is best to use metal cans for fuel preparation. they do not react with oil additives and gasoline components, ensuring the safety of the operator and the environment. In addition, metal cans can stand for longer in direct sunlight, while plastic containers begin to melt in hot weather.

Oil types

Two-stroke oil is a separate lubricant for internal combustion engines. These lubricants differ from others in their properties. As already noted, special requirements are imposed on two-stroke oils.

For gasoline 2-stroke engines, oils must necessarily have the following qualities.

  • The minimum amount of ash and coke that forms in the cylinder during combustion. The lubricant, ideally, should completely burn out.
  • It should dissolve easily and completely in the fuel.
  • The lubricant must have lubricating, antiwear, protective properties at elevated temperatures. And it should also protect well against corrosion.

If the lubrication system is separate, then it is necessary that the oil remains fluid and well pumped. If we take into account the scope and specificity of 2-stroke engines, which serve as motors for scooters and mopeds, engines for lawn mowers, boat motors and others, then there are separate requirements for the toxicity of the material.

If a lubricant gets on the soil, then it must be as safe as possible for the environment, and when it gets into water, it must decompose very quickly.

Such oils must comply with TC-W3 and 2 T standards. Very often they can be distinguished from analogues by their color, as they are additionally colored. They are mostly blue. Even when mixed with gasoline, it can be seen well.

According to the 2 T standard, such lubricants are used in air-cooled engines ranging from lawn mowers and chainsaws to motorcycles (light). But for use in outboard motors with water cooling and jet skis, TC-W3 oils are designed.

There are low-viscosity oils for winter operation. Lubricants can be based on:

  • synthetic;
  • semi-synthetic;
  • mineral.

How to dilute chainsaw oil. expert advice

Proportion for chainsaw Friendship

For engines use fuel of low octane numbers. The unit shows the highest performance when filling the engine with AI-76 and AI-80 gasoline.

It is recommended to dilute gasoline and oil according to the following algorithm:

Chainsaw Oil to Gasoline Ratio

To refuel a 2-stroke powertrain, the operator must dilute the chainsaw gasoline with properly balanced engine oil. The fuel used must initially be unleaded and have an octane rating of at least 90.

The proportion of oil and gasoline for the chainsaw plays an important role when diluting the fuel. In most cases, the recommended mixing ratio is 1:50. This means that you need to dilute 100 ml of oil in 5 liters of fuel, or take 20 ml of lubricant for 1 liter of gasoline.

If the operator has to refuel and run in a new chainsaw, the proportion will change to increase the amount of engine oil used. In these cases, the ratio of fuel to lubricant should be approximately 1:40. It is necessary to prepare the mixture in this ratio during the running-in period, that is, during the procedure, it will be necessary to use up 2-3 full tanks of fuel saturated with oil. At the same time, if the gasoline mixture is oversaturated with engine oil, and its proportion is 1:30, this will lead to the rapid appearance of a thick layer of carbon deposits on the cylinder surface and piston walls. This will result in a serious breakdown of the crank mechanism.

For more powerful Chinese chainsaws, you need to use more engine oil. over, it is necessary to prepare such a mixture throughout the entire period of operation of the chain tools. Since gardening equipment from China has an initially increased power, its moving parts are subject to more intense friction. To prevent them from overheating and premature wear, you need to regularly refuel the saws with a mixture prepared in a ratio of 1:25.

Component recommendations

Even the owner of a chainsaw, observing the proportion to the gramme, can harm his tool if he uses substandard or inappropriate components. The general recommendation is to use special fluids.

Saws of the new generation

Sometimes the future is not easy to predict, but there is a lot to be said about new chainsaws that have not entered the mainstream market. It’s just a matter of time before the electronic engine management system is used in the world of chainsaw development.

Modern carburetors will soon give way to what in the automotive world is called electronic fuel injection system. These technologies control the operation of the engine and regulate the flow of the fuel mixture. This system will enable professional tools to achieve greater work efficiency and reduce emissions.
