How to dilute chainsaw oil - expert advice

The durability and reliability of a chainsaw is determined not only by its operating conditions, but also by the quality of the fuel used for refueling. In addition to the special conditions of use when grinding in parts during the first few refuelings, the quality of the fuel mixture also needs to be paid attention to.

Professional Stihl chainsaws are equipped with two-stroke engines that require high-quality fuel - a dosed mixture of high-octane gasoline and oil, designed to operate the engine at high speeds. The correct choice of gasoline and oil for the Shtil chainsaw is the key to long and successful operation of this unit.

How to dilute the components of the mixture

As mentioned above, gasoline and oil should be diluted in a specially prepared container.
You shouldn't 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 about 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 with chainsaws.

Before diluting the fuel, it is necessary to clean and degrease the neck of the gas tank. It is advisable to fill through a filter. Any rag will serve as a filter

After use, the remaining mixture must be drained and disposed of. Remember that 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 you do not dilute the fuel, then carbon deposits will form more often, the necessary lubrication of the pistons will not occur, which will result in an increase in the temperature in the engine. And this will lead to the pistons breaking. Or the owner of the saw will inhale toxic fumes in large quantities throughout the entire operation. Thus, he will develop health problems and break the instrument.

Mixing oil and gasoline

If you use low-quality lubricant and fuel, they can also lead to engine damage. It is not recommended to dilute motor oil made for cars. Fuel must be purchased with a high octane number.

Modifications

Like its older brother, Shtil MS 180, the MS 170 chainsaw can have an improved modification. For example, the STIHL ElastoStart system can be installed on it, which reduces the engine compression resistance due to an additional starter spring installed.

Another useful option of the MS 170 chainsaw is the quick chain tension system. You can tighten the chain with it even without using a special key, which is very convenient. As a rule, keys are often lost. Photo of the system below.

The side chain tensioner is also designed to facilitate the operation of the tool, since in the standard version it is not very convenient to adjust the chain tension of this chainsaw. The adjusting screw is located behind the tire on the crankcase, and when the chain is tensioned, the tire gets in the way. In some cases, when the chain is accidentally touched, it can cause hand injury.

Oil dosage in Chinese version

Many Chinese-made chainsaws are simplified copies of popular European-designed models. The lack of special materials and proprietary technologies contributes to the preservation of the outdated proportion of gasoline and oil in the ratio of 25:1.

The doubling of engine oil consumption is compensated by its lower cost. According to the developers, original components are introduced into Chinese oils that help increase the wear resistance of power units and actually extend their designated service life.

According to independent experts, the best brands of Chinese motor lubricants correspond in quality to analogues from European manufacturers in the mid-price range. This is the level of branded motor oils of the Standard group and partially Super.

Types of oils

When deciding which oil to use for a chainsaw chain, you should first of all follow the recommendations of the tool manufacturer. Of course, the best lubricant is original oil. If it is unavailable, you can use ordinary automotive lubricant.

Which oil to use for a chainsaw depends on its future use, and the classification of the lubricant depends on the composition. It is divided into groups:

• Synthetics.
• Semi-synthetic.
• Mineral.

Synthetic brands can withstand temperatures of minus 40 degrees. Semi-synthetic products operate in the average temperature range (-30 - +25 degrees). Sometimes manufacturers add special additives to its composition to improve the characteristics of a lubricating product. They change the properties of the oil, making it possible to select a lubricant that suits future operating conditions. Depending on the engine type of the tool, oil consumption occurs. In a four-stroke engine, the combustion chamber has a special design. Therefore, there are no traces of soot left in it. To achieve a similar effect in a two-stroke engine, you have to fill in special oil

It is very important that the fuel matches the lubricant

Chainsaw sprocket lubricant

To increase the life of the sprocket and also reduce the friction force, the manufacturer installs a needle bearing. For its periodic lubrication, Shtil chainsaw oil is used.

. What kind of oil is used to lubricate the chain?

Chainsaws. A popular tool for those who deal with numerous household chores. They can be used for different purposes. collect firewood, trim dry branches. But in order for the device to last as long as possible, it is necessary to take proper care of it by choosing the right different connections. A special role is played by chain saw oil, which is selected depending on the principles of the tool and its characteristics.

What to count?

Proper care should be taken when lubricating chain saws. , you should choose special oil that will not damage the oil pump

In addition, this will ensure high-quality operation of the self-lubricating system. The chain requires proper storage, i.e. immersion in oil, and if worn, do not attempt it. it is easier to replace. What is the best chain oil that is safe and meets all requirements?

Types and composition

The choice of specific oil depends on where and how the chainsaw operates. Mineral compounds are suitable for the summer and warm seasons. In other cases, it is better to use synthetic or semi-synthetic oils. If it is necessary to lubricate the chain, there is no need to use waste oils, which will clog the fuel system and then cause serious damage to the tool.

The chainsaw oil must be thoroughly cleaned to ensure that the lubricant is applied correctly and accurately. If you use poor-quality connections, there will be no contact between the saw elements and the bars, sparks will appear, and then the moving parts of the saw will wear out.

How to choose?

Each chainsaw has a two-stroke carburetor engine and two tanks: one filled with gasoline, the second. oil. When choosing a lubricant composition, zoning plays an important role. it should be minimal. Another important indicator is resistance to low temperatures: the oil should not freeze at extreme temperatures, which will ensure the quality of the entire tool.

For lubrication, it is recommended to use adhesive chain oil containing special substances that allow the composition to adhere well to the chain. High-quality oil will remain on the chain as it rotates, and the chain itself will be more reliable in operation.

Another important indicator of a lubricant is density: if the composition is liquid, it will be consumed in large quantities

To avoid harm to the environment, it is important to use vegetable oil when using a chainsaw. its waste will decompose in the natural environment

Which chainsaw oil should you choose because modern manufacturers offer a wide range of options? Among the specialized manufacturers, we can mention such brands as Divinol, Bio-Kettenol, Ravenol, VegOil, Mobil, Castrol, Shell. Let's take a closer look at the features of their products.

Divinol

This brand offers high quality chain lube that has good adhesive and lubrication properties, so that the lubrication is done efficiently and the hinges and chain loops are reliably protected from wear. The optimal combination of viscosity and temperature characteristics guarantees that this oil can be used at any time of the year and at any temperature.

Divinol offers various oils for chainsaws

What's the use of them? Zweitaktoel FF pays attention to economical consumption, connection to any fuel, prevention of aging of the fuel mixture and excellent corrosion protection. In addition, this oil can be used at any temperature.

Divinol Kettenol and Divinol Kettenol Bio can be used to lubricate chainsaws and chainsaws. With these connections, chain links and joints can be reliably protected from wear, while ensuring economical oil consumption. High-quality organic oils of this brand provide excellent lubricating and adhesive properties, so their use is not only simple, but also environmentally safe.

MS180 A couple of points about what fluids need to be filled

into a chainsaw. Always keep an eye on.

Choosing chain oil

After each refueling of the chainsaw with the fuel mixture, do not forget to check the amount of oil in the oil tank. In a chainsaw, an oil pump delivers lubricant to the bar along which the saw chain slides. Normally, both tanks - fuel and oil - should be refilled at the same time. Oil for lubricating the chain must be poured into the appropriate tank up to the neck. Otherwise, it may run out before the fuel, which will lead to overheating of the chain and bar.

Chainsaw chain oil must be formulated specifically for this purpose. The use of other lubricants is ineffective and reduces the service life of not only the saw, but also the unit tire. This is explained by the fact that chain oil contains adhesive additives, thanks to which the lubricant literally “sticks” to the chain. This property of the oil reduces its consumption, as a result of which the lubrication of the chainsaw bar and saw chain improves, and their service life increases.

Another important parameter of chain lubrication is its thickness. If you are going to use a lubricant that is not intended for chainsaws, you may notice that oil leaks while the unit is running or after it stops. This fact indicates that the lubricant is too liquid. In addition, the liquid lubricant will quickly scatter in all directions and, accordingly, quickly run out.

When operating a chainsaw in winter, it is necessary to use oil designed for low temperatures to lubricate the chain, otherwise the oil pump will fail. Therefore, the lubricant remaining in the tank must be replaced with low-temperature lubricant.

Leading manufacturers of gas powered tools, such as Shtil, Husqvarna, Makita, Bosch and chainsaw component manufacturer Oregon, recommend the use of special highly adhesive oils, including biodegradable ones. But oils from well-known brands have the only drawback - the price is 300 rubles per 1 liter and more. In addition, the lubricant in the reservoir can thicken over time and clog the channels. For this reason, it has to be drained, and this already increases consumption. But despite this, we have to admit the fact that only the use of special lubricants can extend the life of the chainsaw.

Chainsaw oil ROLF Garden 2T

The oil is produced on a synthetic base, which ensures the highest quality. Therefore, ROLF Garden 2T has low smoke, burns completely and with extremely low soot. At the same time, it reliably protects the engine from wear, since it has a balanced additive package. When the engine runs for a long time on the ROLF Garden 2T, rapid contamination of the muffler with carbon deposits and products of incomplete combustion of oil, which reduce the power of the chainsaw, is eliminated.

The oil was developed specifically for garden equipment, where the main method of lubrication is a ready-made fuel mixture. This was taken into account when creating ROLF Garden 2T, and the product achieved excellent stability when mixed with gasoline. The finished composition during storage prevents delamination and clogging of carburetor channels. The oil does not reduce the octane number of gasoline and eliminates the risk of detonation under load.

Due to its low freezing point, ROLF Garden 2T is also ideal for winter work, which maintains the efficiency of engine lubrication with the fuel mixture. The oil burns well in the engine, reducing the risk of spark plug failure. In this way, the amount of maintenance required for the chainsaw can be kept to a minimum.

The quality of the oil is confirmed by approvals from the largest chainsaw manufacturers. In addition, ROLF Lubricants GmbH offers a simple and effective anti-counterfeit system: all of the company's products are packaged only in tin containers. As practice shows, counterfeit goods are practically never found on the market under such conditions: for manufacturers of counterfeits, packaging in plastic is more profitable.

Advantages and disadvantages

For private work, the tool shows good performance. The saw becomes a reliable assistant in woodworking, felling trees and removing excess branches. The model proved to be excellent in the construction of log houses and the arrangement of landscape elements made of wood.

The main advantages of the model:

1. Price/performance ratio.
2. Reliable mechanisms, durable materials, a minimum of elements that can break.
3. Ergonomic handle shape. High-quality balancing of the body.
4. Well designed levers and control system.
5. Effective vibration suppression system, low noise level.
6. Easy starting at low temperatures.
7. During repair work, it is easy to reach the main parts of the mechanism.
8. Ensuring high worker safety even when sawing hard-to-reach objects.
9. The manufacturer has provided an effective security system and removed settings that were unnecessary for inexperienced users.

The device has good technical performance for an entry-level saw. The manufacturer did not skimp on materials, carefully thought out the control system, and provided an effective security system. Additional options prevent vibration and uncomfortable jolts when starting the engine. Reviews about the Stihl MS-180 C-BE reveal the main drawback - the device is demanding on the quality of consumables and their high cost.

Proportions for Swedish Husqvarna chainsaws

What exact rate of lubricant is required to prepare the combustible mixture necessary for the normal operation of a two-stroke gasoline internal combustion engine? Buyers will learn about this from the instructions supplied with the product. But documentation is often lost among papers. In this regard, it would be useful to remember that manufacturers use transmission lubricant for mixing with gasoline. The Swedish company is known on all continents of the planet for supplying reliable goods to trade markets. Oil for Husqvarna chainsaws is strictly recommended by the manufacturer.

Depending on how much power is required to be obtained from the units, select the appropriate component dilution:

Along the way, we inform you that only unleaded gasoline of the AI-92 or AI-95 brands is used. A leaded combustible product is considered a poor choice for internal combustion engines, as it shortens the engine's service life.

Structure company of Husqvarna HP

The brand structure of the Swedish manufacturer Husqvarna HP includes a company that produces mechanized hand tools and lubricants for them, and effective chemical additives.

Chainsaw manufacturer Partner has developed an original ratio of fuel and oil for two-stroke power plants:

There are moments of non-compliance with the standard approach to dilution with a lubricant product of the company’s own production. This is when the internal combustion engine goes through the break-in stage. The fuel mixture allowed for the engine is 1:40.

Important Terms

The power plants in chainsaws are internal combustion engines, fueled by certain brands of gasoline diluted with the required parts of oil.

Knowledge and strict adherence to the composition of a combustible mixture is the key to long-term operation and productive use of small-scale mechanization units.

The main fuel component is AI grade. It is not recommended to use below or above 92 octane. Optimal for many types of mechanized sawmills, domestic or foreign made.

The ideal ratio of gasoline and oil for a chainsaw:

• increases the productivity of the unit;
• increases service life;
• creates money savings.

The instructions attached to the purchased goods indicate the consumption rates of fuel and lubricating fluid. Violation of the requirements leads to loss of power and premature wear of the internal combustion engine. The truth was obtained through research methods, empirically in our country and abroad.

Storage

If the saw will not be in use for a long time, for example in winter, then clean it before putting it away; Lubricate the sprocket on the bar and the chain with oil. It is also necessary to drain the gasoline from the tank. In this way, we will protect the tool from damage, since 2-stroke oil has its own expiration date and, when mixed with gasoline, loses its properties over time. If you start the saw after six months, the engine will suffer significant wear.

After the saw has been idle for a long time, it is necessary to fill it with fresh fuel mixture. Old diluted gasoline from last season must be disposed of.

Compliance with these simple maintenance rules can significantly extend the life of your unit.

General characteristics of Huskvara chainsaws

Mixture proportion for “Calm”

The German family company Stihl has production facilities in many countries around the world. The office is located in Waiblingen. Among the range of products produced for the needs of forestry, small-scale mechanization equipment takes pride of place.

Today a liquid golden age has arrived for the Stihl chainsaw:

The calculation is simple. We know that 1 liter of flammable liquid equals 1000 milliliters. Divide the value by 50, we get 20 milliliters of oil. Using a similar algorithm, its volume is determined, recommended in a ratio of 1:40. Having made simple calculations, we get the value of 25 milliliters.

Product manufacturer STIHL

The history of the STIHL brand dates back to 1926, when Andreas Stihl founded. Initially, the company specialized in creating working boilers and the first “washing machines”, and later, with the money earned, the first model of a chainsaw was created. This unit, despite its enormous weight (48 kg), quickly conquered the market and began to be sold very successfully to countries near and far abroad.

The 90s marked the beginning of a family business for the company. Almost all members of the Stihl family began to take part in the life of the company.

In 1995, the AG&Co Holding was created, the main base of which was in Waiblingen and Diesburg.

Since 2002, a complete stranger has become the head of the board of directors of STIHL AG. At that time, boss Hans Peter Stihl headed the company's supervisory board and took over the chairmanship of the commission of STIHL Holding AG&Co.

After another 2 years, the company’s modern development center opened, and already in 2006, a new assembly plant started in China.

Today, the company is successfully developing, introducing new ideas and even more practical approaches into its work. STIHL's inventions top the chainsaw ratings in terms of reliability.

What happens if you don't follow the manufacturer's recommendations?

In case of violation of the rules for the manufacture of fuel and lubricant mixtures and non-compliance with the proportions when adding oil to gasoline on the Stihl 180 chainsaw; The following difficulties arise:

• As friction increases, wear on the working surfaces of parts increases.
• An insufficient amount of lubricant will lead to bearing failure.
• The full functioning of mechanical components is disrupted due to early wear of parts, their service life is significantly reduced.
• When using low-grade gasoline and oils, the performance of the unit decreases with the following breakdown of key components and parts.

Fuel is prepared before refueling the saw, avoiding unnecessary contact with oxygen. After finishing the work, the remaining mixture must be drained.

Why do you need to maintain the proportion of gasoline and oil?

Many buyers, when purchasing a chainsaw, are perplexed as to why the exact amount of oil and gasoline should be added to the oil recommended by the manufacturer. It's all about the subtleties of a two-stroke engine, which differs from its 4-stroke counterpart in a number of specific design solutions.

One of them: the production of a single-cylinder engine in which there is no crankcase for filling lubricating mixtures. This is seen as a technological success of its time.

You can imagine how the incoming combustible mixture loses oil molecules that settle on the cylinder stacks. Subsequently, it creates a sliding protective film in the rubbing components and parts of the internal combustion engine, reducing the physical contact of the piston rings with the cylinder wall, connecting rod and crankshaft.

To ensure maximum performance of the unit, long-term operation is achieved by the correct ratio of pure gasoline to the recommended oil. Violation of the rule guarantees a quick exit of the instrument from its functional state. A breakdown of the internal combustion engine will require significant funds for repair or replacement with a new analogue.

Many users of hand-held power tools consider the oil container present in the unit to be a reservoir for lubricant and power unit. This is fundamentally wrong. The lubricant is intended for the chain during operation. But only. The oil tank is a priori not connected by pipeline to the engine.

Husqvarna chainsaw oil

, which is also a major manufacturer of chainsaws, produces its own set of lubricants for its equipment. Motor oil for Husqvarna chainsaws today is officially supplied to the Russian markets in only one form: Husqvarna HP.

Husqvarna HP gasoline chainsaw oil is a semi-synthetic product that fully complies with all requirements in force in the Russian Federation.

This lubricant goes well with equipment, but can also be successfully used in saws from other manufacturers. It has excellent lubricating properties and does not leave deposits on the parts of the cylinder-piston group.

How to dilute oil for a Husqvarna chainsaw and not make a mistake if there is no dispenser on the canisters with the products of this company? Here, all owners of gasoline saws are recommended to acquire a measuring container with a division value of 1 ml.

The fact is that both a lack and an excess of lubricant will have an equally negative impact on the service life of the piston group of a two-stroke engine. The deficiency will accelerate piston wear.

Please note: Scoring and grooves may appear on the piston and cylinder. An excess can lead to the formation of deposits and increased smoke, and the service life of the spark plug will be shortened. What lubricant should I use for Husqvarna equipment if it is not possible to purchase the original? The answer is simple: any with similar properties

Stihl products will also work.

What lubricant should I use for Husqvarna equipment if it is not possible to purchase the original? The answer is simple: any with similar properties. Stihl products will also work.

Fuels and lubricants

Petrol

Engine manufacturers recommend using high-octane gasoline AI-92, 95. The use of fuel with various additives to increase the octane number is not allowed. During this time, the process of resin formation and polymerization may occur in it, which negatively affects the operation of the engine.

We do not recommend consuming gasoline that has been stored for more than 60 days.

Most chainsaw engines use leaded gasoline. If you purchased a tool with a catalyst (the tank cap will be green), we recommend unleaded gasoline.

Important: you should not save money and use gasoline with an octane number below 90. It is also not recommended to use gasoline with an octane number higher than 95. This leads to premature wear of the engine piston group.

Oil

The design of two-stroke air-cooled engines does not provide a separate lubrication system. Moving parts are lubricated by the oil present in the fuel mixture. Therefore, it is so necessary to use only high-quality oils from trusted manufacturers.

Recommended oils for refueling chainsaws:

• STIHL HP – developed specifically for chainsaw engines. It has proven itself in all weather conditions and ensures ideal engine operation.
• Husqvarna HP is an oil from a well-known manufacturer of garden equipment. Special additives reduce carbon formation on the engine crankcase, which can occur due to the use of low-quality fuel.

• Oleo-Mac Prosint 2T is a multifunctional oil with synthetic esters. Protects engine parts from corrosion, reduces wear of mechanisms and parts.
• CHAMPION JASO FD is a high-quality oil from a well-known company. Provides good protection for all moving engine parts;
• Vitals Semisynthetic is an all-season oil for budget chainsaw models, intended for use at temperatures from -20 to +40C 0 .

Important: the use of mineral, semi-synthetic and synthetic motor oils is prohibited. They are intended for engines of a different type and do not have the necessary properties.

Preparing the fuel mixture for a chainsaw

Let's look at everything in order:

Petrol

Gasoline must have an octane number of at least AI92. You can also fill in AI95, but its quality at our gas stations leaves much to be desired, so if you are not sure of the quality of 95, then it is still better to take AI92 gasoline for diluting gasoline in a chainsaw. You should also not take gasoline that has been sitting for a long time in a canister, tank or any other container. Gasoline for preparing the fuel mixture for a chainsaw must be fresh, otherwise it loses its properties, in particular its octane number, and even if you run the chainsaw on such fuel, it will not produce full power. And the saddest thing in this case is that the failure of a chainsaw due to low-quality 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 such a breakdown!

Oil

Oil for 2-stroke engines according to the classification of the American Petroleum Institute (API), the American Petroleum Institute has the API-TB class, there are also API-TC class oils, but they are designed to work with lower loads than most common chainsaws. If you take the power class according to the Japan Automobile Standards Organization (JASO) classification, then focus on the JASO-FB 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 completely, which means it is better to take synthetic oil, since it produces less smoke and combustion residues. And if you fill your chainsaw with oil for four-stroke engines, which will not burn completely and as a result carbon deposits will form, then your CPG will fail. The best thing to guide you when choosing oil for a chainsaw is the instructions for it.

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.

Since they often come from search engines with queries like “how much oil to pour into 1,2,5 liters of gasoline,” I’m adding another table under No. 3 in which you can find out how much oil to add to gasoline according to the accepted proportions. The proportions can be found in Table 2 or, more precisely, in the instructions for your chainsaw.

Devices for diluting the fuel mixture

Of course, you can use a canister, syringe or measuring bottle, but there are more convenient options. It is worth noting here that, for example, Stihl oils are available in 2 types of packaging - with and without a dispenser. With a small difference in price, a bottle with a dispenser greatly simplifies the process of preparing the mixture. There are also many different canisters with a dispenser, with separate compartments for oil and gasoline. All these devices reduce the preparation time for starting and operating the chainsaw.

Stihl canister with compartments for oil and gasoline

This canister has two compartments for storing oil and gasoline separately. The gasoline container has a volume of 5 liters, and the oil container has a volume of 3 liters. Often, many owners of gas-powered tools with two-stroke engines carry oil in this canister in one compartment and a ready-made fuel mixture in the other.

Husqvarna canister with compartments for oil and fuel mixture.

Husqvarn canisters have a special feature: the oil container can be detached from the main one and used separately.

Basic rules of application

Two-stroke chainsaw oil is most often created on a mineral base. Less often it is synthetic or semi-synthetic. According to technology, oil for 2-stroke chainsaw engines is mixed with fuel before filling the tank.

Table of proportions

Pouring lubricant directly into the tank is also practiced, but this is not the most reliable way. Especially if the tank was completely empty. In this case, there is a possibility that gasoline will partially enter the system without lubrication. And the engine will run dry for some time.

The gasoline/oil ratio for chainsaws is strictly determined by the saw manufacturer. In some cases, oil manufacturers indicate their proportions. This is typical of expensive synthetic lubricants. And the gasoline/oil ratio in this case increases towards fuel.

If, when using a lubricant, it is discovered that a wet oil deposit remains on the spark plug, and dirty waste drips from the exhaust pipe, these are clear signs of incomplete combustion or the use of low-quality lubricant. It is necessary to reconsider the choice of motor oil for a chainsaw and the proportion of its use.

How to dilute gasoline for a chainsaw

Let's look at how the mixture for a chainsaw is prepared. It is necessary to calculate the correct ratio of gasoline and oil for the chainsaw. For chainsaws, use fuel with a high octane rating: AI-92 or AI-95.

To prepare the fuel mixture, you need to add 30 g of oil to 1 liter of gasoline, which corresponds to the design of the saw. The resulting fuel liquid is poured into the fuel compartment. Before diluting gasoline, you should consult with service specialists who specialize in repairing chainsaws.

In order for the saw to have a long service life, it is necessary to properly prepare the gasoline-oil mixture, for which only grades AI-92 and AI-95 can be used. The fuel must be unleaded, otherwise the internal combustion engine may break down. You should not use an old product that has expired, because over time the fuel may change its octane number. The proportion of lubricant and fuel is strictly maintained.

You should not skimp when choosing oil for chainsaws of the Husqvarna brand and others. The proportions must be observed due to the fact that excess oil can lead to the growth of carbon deposits on the chainsaw components. Excess gasoline can cause piston damage and engine failure. So, 1 liter of fuel is mixed with 20-50 ml of oil. Husqvarna recommends adding 100 ml of lubricant to 4 liters of gasoline. This proportion is suitable for saws with a power of up to 1.5 kW.

For structures with a power of more than 1.5 kW, an oil proportion of 1:50 is used. That is, you need to dilute gasoline like this: add 5 liters of chainsaw gasoline per 100 ml of oil. When refueling a chainsaw, Partner recommends diluting the fuel fluid at the following rates: add 100 ml of lubricant per 3.3 liters of fuel.

When using supersynthetic oils, the ratio is 1:100. That is, the fuel mixture for a chainsaw must be prepared according to the recipe: add 100 ml of lubricant to 1 liter of fuel. When choosing components, you need to use the information that is given in the instructions for any modification of the saw.

Let's consider in what container you can mix fuel. In stores there are canisters with measuring divisions, in which there are 2 holes: for fuel and for lubricant. Using such a canister, you should pour both ingredients, screw on the lids and mix the substances, tilting the canister in different directions.

Plastic bottles and other containers are often used to mix ingredients. You should be careful with plastic and glass. Static electricity may occur when mixing components. It is necessary to ensure that no pebbles, sand or drops of water get into the fuel mixture. The fuel mixture must be mixed well. The prepared fuel mixture cannot be stored for more than a month, as oxidation of the materials may occur and the composition of the mixture may change.

Engine failure caused by expired fuel is considered non-warranty by the service. In this case, the cost of repairs can reach 80% of the price of a new structure.

After all the work using the chainsaw has been completed, you need to use up the remaining fuel, turn off the engine, and remove the remaining mixture.

For the best operation of the device, it is necessary to make a mixture that will ensure uninterrupted operation of the engine and complete combustion of the gasoline-oil mixture without causing soot, smoke or damage.

Review of engine oil manufacturers

Among the manufacturers producing the best two-stroke oils, we can confidently name 2 leaders - these are the companies Husqvarna (Husvarna) and Stihl (Shtil). Companies produce not only conventional mineral oils, but also synthetic lubricants designed for 2-stroke engines operating in harsh conditions.

Husqvarna HP

This is a Swedish manufacturer, which includes several well-known brands, including the Partner company, known for its garden equipment for semi-professional and professional use. Husqvarna produces not only equipment, but also high-quality lubricants used on almost all brands of power tools.

The photo below shows Husqvarna HP 2-stroke oil, which contains special additives that can compensate for poor fuel quality, which is not uncommon in our country. After all, the octane number of gasoline purchased at a gas station does not always correspond to the declared one.

This lubricant is green in color and contains a semi-synthetic base. It can be packaged in both 10-liter and liter containers. The mixture is diluted in a standard proportion of 1:50 (20 g per 1 liter of gasoline). But when the engine has not yet been broken in, or work is to be done in the cold, the proportion can be increased to 1:40.

Stihl HP

The lubricant was specially developed for engines of Stihl equipment. It has a mineral base, has high lubricating and cleaning abilities and can be used at an ambient temperature of at least -10°C.

The bottle has a special dispenser that allows you to mix the fuel mixture without using additional measuring containers.

The lubricant is red in color and can be stored for no more than 4 years in a closed container. The latter can have different capacities, both large and small (for one-time refilling). For example, there is a 20-gram container on sale, the contents of which are added to 1 liter of gasoline. This is a very convenient option for owners of chainsaws who use them occasionally. Important: the mixture of gasoline with this oil cannot be stored for more than 1 month, since during this time it will already lose its lubricating properties.

Stihl HP Ultra

The oil belongs to the highest category. It is created on a completely synthetic base, has a green color and has high lubricating properties, and thanks to salt-free additives it does not create soot.

The oil was specially developed for lubrication of engines operating for long periods of time at high loads and low ambient temperatures, down to -25°C. In addition, this lubricant does not harm the environment. If it is spilled on the ground, it will decompose by 80% in 21 days. The lubricant is packaged in 100 ml and 1 liter bottles.

Rules for preparing the mixture

Even experienced lumberjacks do not always correctly prepare the fuel mixture for a chainsaw if the work is done in a hurry.

The algorithm of actions is as follows:

• prepare a plastic container holding 2.5 liters or less;
• a measuring container must be present - many people use a regular medical syringe;
• First, fuel is poured into the container, and then a precisely measured portion of oil;
• The final task is to carefully dissolve the oil product by actively shaking the consistency.

It is recommended to store the finished flammable product for 14 days. If more, the oil will settle to the bottom of the container. A new shake of consistency will be required. Busy people often forget about this.
