Dilution proportions for chainsaw gasoline

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 cause 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.

Chainsaw fuel mixture: how much oil is needed per liter of gasoline

Any gasoline equipment will perform work properly only if the operating rules and the correct preparation of the fuel mixture are taken into account. This feature also applies to chainsaws. How much oil per liter of fuel to use for refueling and how to properly prepare fuel, we will analyze in more detail.

Which brand to use motor oil?

For each model, the manufacturer advises a list of materials to be used. It is better for the user to adhere to these recommendations, because the warranty does not cover tool breakage due to inappropriate fuel and lubricant. In this case, the owner himself pays for the repair of the chainsaw, which can be up to 80% of its cost. When you can’t follow the manufacturer’s recommendations, try to follow these rules:

  • Use oil only for 2-stroke engines.
  • Do not use after expiration date.
  • Do not add used oil with a large amount of impurity to gasoline, as the mechanisms of the tool can be damaged.
  • Chain lubricant cannot be used for the fuel mixture.
  • It is preferable to use synthetic and semi-synthetic oils, which are more expensive than mineral oils, but do not form harmful deposits..

Why add oil

At the heart of any chainsaw is a two-stroke internal combustion engine. It is one of the simplest single-cylinder mechanisms and does not have a separate lubrication system. The technology is such that the lubricant must enter the cylinder along with the fuel mixture, settle there, and lubricate the cylinder walls, piston rings, etc. The simplicity of the design of the tool has many advantages, among which the main one is the ability to carry out repair work on the engine and component parts independently..

Diluting gasoline that is poured into the chainsaw is required in order to extend the life of the tool. It is imperative to dilute fuel with chainsaw oil, and if, for some reason, you forgot to do this, then the operation of the tool is absolutely contraindicated..

It is important to know! Chainsaws do not have a special tank for filling oil, which would be used to lubricate the rubbing engine parts, like on cars. This is due to the simplest design of a two-stroke motor. The present tank for oil in chainsaws is designed to lubricate the chain and bar during the operation of the tool.

How to choose the right mineral oil

The correct raw material must be selected before diluting the gasoline with saw oil. This will make it possible not only to facilitate the process of its operation, but also to increase the resource of the engine of the apparatus..

First of all, it should be noted that almost every model of gasoline saws is equipped with a 2-stroke carburetor engine. In their design, there are 2 separate tanks – for gasoline and oil. Domestic devices require the use of conventional oil mixtures, which are used for refueling motorcycles. At the same time, devices of a foreign brand require the use of exclusively branded oil for a chainsaw. If mixtures of a domestic manufacturer were used for this equipment, then its productivity will decrease and its operational life will decrease..

If we talk about what kind of gasoline to pour into the chainsaw, then it will be optimal to use fuel with an octane rating of A-95. As for the oil, it is best to use a branded product..

Typically, technician users dilute chainsaw gasoline with a motor or transmission oil product. Each brand has individual characteristics that can be studied in the attached instructions. For example, the first option is used as fuel for Husqvarna instruments, and the Stihl saw is refueled only with the transmission..

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.

Recommended brands of fuels and lubricants for powering chainsaws

The specific brand of gasoline for the saw is always given in the manufacturer’s instructions. It is recommended to strictly follow it..

There are 2 types of oil:

  • for engine,
  • for chain and bar lubrication.

Do not confuse or misuse them. This is guaranteed to damage the tool. Repairing it can cost almost as much as a new saw..

The most popular chainsaw lubricating oils are:

Each container with branded oil always indicates the proportion of oil and gasoline for a chainsaw (Stihl, Husqvarna, Partner, Ural), which must be adhered to when making a mixture.

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:

  • 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 share 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..

The proportion of oil and gasoline for a chainsaw: how to dilute

All modern chainsaws are equipped with a two-stroke engine. Its long and trouble-free functioning directly depends on whether the proportion of oil and gasoline is correct for the chainsaw. The variety of tool brands and the features of each of them are the reason that this procedure is not easy for most novice users of chainsaws..

Step by step instructions for refueling

If you want to refuel your chainsaw, you need to follow a simple algorithm:

What will happen 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 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 will also not lead to anything good. What exactly will happen can be seen in the attached video.

Lubricants

Stricter criteria for the selection of the oil component. In the best variant, it is a mineral or semi-synthetic engine oil recommended by the manufacturer, intended for operation in high-speed, air-cooled two-stroke internal combustion engines..

The advantage of mineral oils is their lower cost. Their more expensive semi-synthetic and synthetic counterparts are distinguished by improved performance and compliance with environmental standards..

Synthetics:

  • maintain working properties in a wide range of operating temperatures;
  • do not form carbon deposits;
  • contain detergents, antioxidants, preservatives and other additives useful for the operation of the power unit.

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 ratio 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?

Petrol

The main component of the fuel mixture for chainsaw engines is gasoline with an octane number of at least 92. Consumables with expired storage, made on the basis of gas condensate, having water and mechanical impurities in their volume are not suitable for fuel preparation.

  • The opinions of experts on the use of different brands of gasoline are ambiguous. On the one hand, the incomplete compliance of domestic A-92 gasoline with European standards is recognized.
  • On the other hand, the quality of A-95 gasoline is questioned due to the high content of anti-knock additives. It is possible to use this fuel for the preparation of fuel for a chainsaw only with full confidence in its quality..
  • The difficulty lies in the presence of various improving additives, with the help of which unscrupulous manufacturers and distributors increase the performance properties of motor gasoline with a lower octane index..

Also, irreversible changes in the working properties of the fuel occur when it is stored for a sufficiently long time in a plastic container, regardless of the level of its petrol and oil resistance..

Overview of manufacturers of oils for internal combustion engines

Synthetic materials retain their lubricating qualities for a long time. With an increase in temperature, they are able to not burn out after the first heating. Do not emit toxic substances that can harm the health of the owner.

Husqvarna lubricant is used to lubricate engines of the same company chainsaws. It must be diluted in gasoline at a ratio of 1:50. Or 20 grams per liter of fuel. Lubrication of engines from manufacturers of another company must be diluted in a proportion equal to 1 to 33. That is, 30 grams per liter of gasoline. This component for fuel dilution consists of seventy percent mineral elements. Synthetic impurities have been added as well. But their share is a small part – 30 percent. This grease is intended for the CIS countries where there are problems with high-quality gasoline..

The Kreissman, an example of which was given above, is used for two-stroke chainsaw engines. It is necessary to dilute oil with fuel in the same proportions as indicated above. “Kreissman” prevents the formation of soot, perfectly lubricates pistons and other engine parts.

Tool manufacturers usually pack a chainsaw with their own lubrication material. This achieves the best ratio of lubricating properties and extends the service life of the saw..

Features of preparation and storage of the fuel mixture

Safety regulations prescribe to dilute gasoline and oil in a metal canister. This eliminates the risk of static electricity and fuel ignition..

Experts advise to pour oil into an incomplete container, mix thoroughly, and then top up with clean gasoline to the specified level. It should be excluded from everyday practice saving working time by preparing the working mixture directly in the gas tank of the chainsaw.

This technology is fraught with fuel system failures due to the ingress of a large amount of oil into the carburetor, the need for disassembly and thorough flushing..

Chainsaw refueling instructions

Knowing the ratio of the preparation of the petrol-oil mixture, you can start refueling it. Refueling instructions are as follows:

  • First you need to prepare the mixture. Having combined the two main components, you should mix them thoroughly.
  • Place the tool on a clean and level surface. Before unscrewing the gas tank cap, it is necessary to clean or blow off sawdust, dust and dirt.
  • The filler neck must point upwards.
  • Install a small watering can in the neck, then pour fuel
  • Control the refueling process, as the volume of the tank is small, so it fills up quickly
  • Do not fill up to the full maximum, since when the tank cap is closed, the remaining fuel will splash out.
  • After the fuel is poured into the tank, immediately add chain lubricant.
  • The consumption of fuel and chain lubrication is approximately the same, therefore, both tanks must be filled at the same time.
  • After refueling, you can start starting the engine

It is better to start the engine not in the place where the refueling was carried out, but to move to a distance of 2-3 m. The tool is ready for work, and you can start to start it. How the chainsaw engine starts, you can read in this material (link).

How to dilute the components of the mixture

As mentioned above, gasoline with oil should be diluted in a specially prepared container. Do not do this in a gas tank. The latest technology will cause some of the oil to enter the carburetor. As a result, you will have to disassemble the engine and wash it..

Standard dilution ratios are 50: 1 and 40: 1. Such a mixture will not interfere with the combustion of gasoline in the gas tank and will improve the lubrication of the rubbing parts of the mechanism. When running in a new tool, it is advisable to add twenty percent more lubricant. It is recommended to dilute with a large amount of oil in areas with high air temperatures..

Many owners will be interested in information on how to dilute gasoline with oil if there is no measuring container. A twenty cc medical syringe is suitable for this. Although most often measuring containers are included in the kit for chainsaws.

The neck of the gas tank must be cleaned and degreased before diluting the fuel. It is advisable to pour it through a filter. Any rag will serve as a filter.

After use, the remaining mixture must be drained and disposed of. Remember, it is better to overfill than underfill. What will happen if you do not take into account the recommendations, read below.

If you do not follow the instructions, you can render the tool inoperative. For example, if the fuel is not diluted, then carbon deposits will form more often, the necessary lubrication of the pistons will not occur, as a result of which the temperature in the engine will rise. This will cause the pistons to break. Or the owner of the saw will inhale large quantities of toxic fumes throughout the entire operation. Thus, he will earn health problems, break the instrument.

Mixing oil and gasoline

If you use poor quality lubricants and fuels, they can also damage the engine. It is not recommended to dilute engine oil made for cars. Fuel must be purchased with a high octane rating.
