Calm chainsaw how much to pour oil into gasoline

Gasoline selection

The first question that the user faces before starting work is what gasoline to pour into the Stihl chainsaw.

Gasoline for the Stihl chainsaw is filled exclusively with unleaded high-octane gasoline, that is, with an octane number higher than 90. If you fill it with a low-octane gasoline, it is fraught with engine overheating, piston seizure and engine failure. Therefore, it is optimal to pour AI-92 or AI-95 gasoline into the chainsaw, but here the question of fuel quality arises.

Poor-quality AI-92 may “fall short” of the declared octane number, and AI-95 often contains many additives that do not bring any benefit to the engine. In addition, if the additives are of poor quality, they do not last long, and after a few days the purchased fuel can turn into a low-octane fuel, which is not suitable for a chainsaw engine.

At the same time, a good 95 can harm the piston system. “burn” it. Thus, some users found a way out: to refuel the chainsaw with AI-92 gasoline mixed with AI-95. This achieves an optimal balance between octane number and the amount of additives.

What will happen if you pour working off into a chainsaw

If you do not want your chainsaw to fail at the wrong time, use only high-quality fuels and lubricants. It is forbidden to mix working off with gasoline. The reasons for this are the following factors:

  • Other viscosity of the material, therefore, mining is not able to provide effective lubrication of rubbing parts and mechanisms
  • The mining contains small particles of metal and shavings, which, getting into the tank, will cause clogging of the fuel filter and channel. If the grease enters the cylinder together with small particles, they will leave their imprint in the form of accelerated wear of the piston rings.
  • Emitting a lot of black smoke, which indicates burning oil

It is impossible to pour surrogate materials not only into the gasoline tank, but also into the chain lubrication tank. What happens if you use the development in the tank for chain lubrication can be seen in the video.

Using the instructions, you can independently prepare the correct fuel mixture on which the chainsaw will work. If the fuel mixture is diluted incorrectly, not only will the tool life be reduced, but also its performance will decrease.

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.

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 (calm, husqvarna, partner, ural), which must be adhered to when making a mixture.

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.

Chapter 7: Fueling Your STIHL Chainsaw

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

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 the preparation of the fuel mixture that is close to ideal, and provides lubrication of the rubbing parts of the crank mechanism and the 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, 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?

Oil selection

Unlike four-stroke engines, Stihl 180 chainsaw oil is poured directly into the gas tank, after having been mixed with gasoline. It is recommended to fill the chainsaw with the oil specified in the instructions for this model.

Under no circumstances should you use oil intended for low-speed engines (boats, scooters, etc.).

It can significantly reduce the life of the engine, and if traces of such a substance are found in the cylinder-piston group, the tool will be considered withdrawn from the warranty, that is, it will not be subject to warranty repair or exchange.

Stihl synthetic and mineral oils for chainsaws are sold in bottles or cans of different capacities: from 100 ml to 5 liters. Mineral ones have a lower cost, while semi-synthetic and synthetic ones ensure complete combustion during engine operation, i.e. no carbon deposits and a minimum of toxic compounds in the exhaust.

In addition, synthetic oils retain their properties over a much wider temperature range, and also contain special additives that are useful for engine operation: antioxidant, detergent, preservative, etc.

You can choose an engine oil for your tasks depending on the saw model and the frequency of its use: the oil consumption during the operation of the device is low, and given the shelf life of semi-synthetic and mineral lubricants, there is a risk of simply not having time to use even a liter bottle to the end.

So with a small estimated volume of work, you can not buy a bulk canister, but limit yourself to a bottle. Only Stihl mineral greases do not have an expiration date.

Chainsaw refueling instructions

Knowing the ratio of the preparation of the petrol-oil mixture, you can start refueling it. The refueling instruction is 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.
  • Fuel consumption and chain lubrication are 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).

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.

How to dilute gasoline with oil in a chainsaw

A chainsaw is a simple tool used by ordinary people, and horror villains and girls in music videos. However, as soon as you face the professional use of this tool in business, the myths in your head are dispelled instantly. One of the nuances of its use is refueling with gasoline. Even in gasoline for Soviet motorcycles, they diluted with oil, in the same way for saws. If you are interested in why and how much to pour oil into gasoline for a chainsaw, then you can find the answers in this article.

How the saw works?

In order to properly understand why gasoline for a chainsaw is diluted with oil, you need to understand the device itself.

First, the chainsaw is powered by a two-stroke engine. That is, in fact, the device is extremely simple in nature. an internal combustion engine and gasoline. However, as a tool, the chainsaw is truly irreplaceable. In addition to the engine, the saw consists of an ignition system, a fuel system, a clutch, a carburetor, an air filtration system, a starter, a chain, a tire, a chain brake, a tensioner and a chain lubrication system.

To ensure optimal performance of the device, regular lubrication of its parts is essential. This will increase both its performance and durability. It’s a bad joke with the serviceability of a chainsaw, because it is one of the most dangerous tools.

So, we figured out the device and the need to lubricate the parts of the chainsaw, now you can move on to the specifics. For the most effective lubrication, the correct fluid must be used. We will help you decide on the choice.

How to choose your chainsaw oil?

In order to answer this question, you need to decide on the type of your device. For chainsaws that are used in the garden and construction industry, diluting gasoline with oil is an indispensable procedure that increases the efficiency and life of the device.

So, what factors should be guided when choosing?

The season in which the saw is used is also important in the choice of oil for your chainsaw. For example, when operating in subzero temperatures, even the highest quality oil may be ineffective due to crystallization. Therefore, the instrument must initially be adapted for use in such weather conditions. For example, it will not be superfluous to be able to warm up the carburetor during operation. If the saw is also stored in an unheated room, then it must be warmed up before use.

Many are faced with a dilemma: which oil is better to use. mineral or synthetic? The synthetic version, as in the case of cars, is more expensive, but does not create carbon deposits inside the device.

We would advise you to choose a synthetic oil from the first start, but if you have been using mineral water for a long time, then you cannot change the type of oil. The reason for this is carbon deposits, which can roll off and damage the saw.

The amount of oil in gasoline for a chainsaw

After the oil is purchased, it remains to decide the last question: how much oil and in what proportion should it be added to gasoline?

Let’s first look at the brand of gasoline that is most commonly used. This is unleaded gasoline AI-95 or AI-92. The specific proportion is most often indicated by the manufacturer of the chainsaw. The most popular ratio is 1 to 50. This ratio is considered optimal for saws from 1.5 kW. But besides this, there are proportions of 1:25 and 1:40 for Chinese chainsaws and for Panther, respectively.

Keeping the correct balance is very important. With a lack of lubricant, the contacting elements are subject to wear. On the other hand, if you overdo it with oil, then the saw will lose in engine resource.

Do not forget about safety precautions when preparing and filling the mixture. it is extremely flammable. Therefore, it is very unwise to prepare the mixture in advance. It is better to send all the hot cooked to the tank immediately. Remains of the mixture in the tank after work should not be stored for more than a few days. Drain them, and use up the remaining gasoline at idle speed.

We also recommend using a special container for diluting gasoline, preferably a canister with two necks for oil and gasoline. Plastic bottles are okay in principle, but they have the risk of static electricity, which can explode. Also, plastic bottles can sag in your hands and accidentally spill the mixture on your hands or saw.

Do not allow water or small particles to enter the mixture. Therefore, thoroughly rinse and dry the canister before mixing. Calibration of your container will also be a mandatory procedure. To keep the ratio of 1 to 50 ideally, make a mark corresponding to the volume 51. Respect the proportions. To add small amounts of oil, use a syringe without a needle. Store the syringe out of dust.

You can find special canisters and dispensers from leading brands that make the preparation of the mixture and its storage as safe as possible.

In conclusion, I would like to say that respect for work and work tools is the key to a successful craft. That is why the correct preparation and use of a mixture of gasoline and oil for chainsaws can be considered an indispensable procedure for a responsible employee.

What are the benefits of the tool? Firstly, long-term work with the characteristics declared by the manufacturer. Secondly, the stability and serviceability of the work. The latter should be of particular interest to the owners, because with the failure of the tool, time and unnecessary funds are lost.

What should be the mixture of gasoline and oil? To prepare it, you will need a container, unleaded gasoline with an octane rating of at least 92 and a lubricating fluid. In most cases, a simple engine or gear oil will work, but the saw will be most effective when using the original oil. Dilute the mixture, and in a special washed canister, avoid the ingress of water and dry particles. Thanks to these rules, the chainsaw will serve you for many years.

HP Super

Designed for high-performance engines and four-stroke engines made using 2-MIX technology. The characteristics are slightly worse than those of the HP Ultra, therefore, at the moment, the HP Super is not supplied to the counters of official Stihl dealers.

Stihl HP Review

Calm HP is a chainsaw lubricant designed to meet high quality requirements and is designed to lubricate the internal parts of the engine during its operation. It is made on a mineral basis and has good combustion performance (it has a low level of emission of harmful substances during combustion).

Original Stihl HP is red and sold in Stihl branded packaging.

It comes in several packaging options, the most popular of which is a one liter bottle with a built-in dispenser. You can also find Stihl HP in cans of five, ten and fifty-five liters.

The smallest package of Stihl HP, which is convenient to use in cases where you need to prepare only one liter of fuel mixture, is a twenty-gram plastic bottle.

Also, the company produces one hundred gram bottles of Stihl HP, which can be used to prepare five liters of fuel mixture.

According to the manufacturer’s recommendations, Stihl HP can be used to mix for any two-stroke engine.

The shelf life, if stored in a closed container, is 4 years.

Chain oil Calm (overview of oils)

The Calm range of oils for chain lubrication includes three types of products, these are:

  • ForestPlus;
  • BioPlus. for chains;

When working, it is necessary to use the type of lubricant that best suits the conditions and duration of work. Let’s consider each of the oils for the calm chain in more detail.

  • Stihl HP;
  • Stihl HP Ultra;
  • Stihl HP S

Which oil to choose

If you are a regular user of a chainsaw and do not use it daily for 6-8 hours, while working only in the summer, then you can use a regular Stihl HP to prepare the fuel mixture for your chainsaw. The optimal ratio of the price and quality of the lubricant made it popular with millions of gasoline tool users.

Stihl HP can be used to mix any two-stroke engine, including moped and boat options.

How to distinguish fake Calm oil

Attackers do not miss the opportunity to make money selling counterfeit products of a well-known brand. Calm oil is no exception. Most often you can find fake Calm HP, since its sales volumes are the highest of the entire line of Calm lubricants.

In order to distinguish a fake from the original, the calm company released a special brochure on which it recorded all the main differences between the original and the fake.

Also, we invite you to watch a video in which, using a specific example, it is shown how a package of high-quality Calm oil should look like and how to distinguish a fake.

Mixing ratio

Very often people ask the question, how much oil per liter of gasoline is considered the norm. It is easy to answer it, because in the instructions for any Stihl chainsaw, as well as on the additive package, it is indicated that when using original Stihl products, the proportions of oil and gasoline should be 1:50. This means that for one liter of fuel, it is necessary to add 20 ml of the additive.

During the running-in period of a new chainsaw, it is allowed to slightly increase the amount of oil by one liter of gasoline. For example, you can dilute one liter, 25 ml of oil, this will reduce the load on the rubbing parts and extend the life of the chainsaw.

How to breed

Stihl saws fuel mixture is prepared by mixing high-octane gasoline and two-stroke engine oil. The proportion of oil and gasoline for a chainsaw is as follows: if the power of the unit does not exceed 1.5 kW, then the ratio will be 1:40 (i.e. 25 ml of oil per liter of gasoline), and if the power is higher than this value. 1:50 (20 ml for 1 l).

Looking at the table of proportions, we will analyze, using the example of two saws of different power, how to mix oil gasoline.

  • For the low-powered STIHL MS 180 with a 2-stroke engine, the dilution will be 1:40. The volume of the fuel tank is only 0.25 liters. In order to mix fuel with oil for one filling, we need 6.25 ml of oil for 0.25 liters of gasoline.
  • For the STIHL MS 660 heavy-duty professional chainsaw, dilute oil and gasoline in a ratio of 1:50. This model has a fuel tank capacity of 0.825 l. In order to understand how much oil to pour for such a volume of gasoline, we multiply 0.825 by 20. It turns out that 16.5 ml of engine oil is required.

In practice, of course, it is not necessary to calculate what proportion of the lubricant will be diluted in the volume of gasoline per filling. Usually, the fuel mixture is diluted in a volume of 1-2 liters, which is enough for several refuelings of the chain saw.

It is necessary to dilute gasoline for the Stihl chainsaw in a separate canister, in no case pouring the components into the saw’s gas tank separately. These engines do not have an oil pump and the possibility of installing it, so only ready-made fuel is poured into the tank. There are even special canisters with two necks on sale to make it easier to dilute the mixture, but you can add oil to gasoline for a chainsaw and in an ordinary canister.

It is better to observe the proportions of refueling the chainsaw as accurately as possible: excess oil will create carbon deposits on the spark plugs and pistons and provoke detonation during fuel combustion. This can shorten the engine life. In addition, the user of the saw in this case is forced to inhale the exhaust gases with unburned fractions. At the same time, excess gasoline can damage pistons due to insufficient lubrication.

Some folk craftsmen, in the absence of special measuring accessories, advise using a plastic bottle: a full cap (from the same bottle) of oil is poured into a half-liter container filled with gasoline. The output is an approximate ratio of 1:50.

It is better to calculate the amount of mixture for refueling in advance based on the expected volume of work and the declared consumption of this engine. The volume of the tank in most chainsaws is about 0.5 liters, a 2 kW engine will consume approximately 1.2 liters per hour of operation (for more precise characteristics of the saw, see the instructions). Thus, it makes no sense to prepare a mixture in volumes exceeding 3 fillings in a row.

Before starting the preparation of the mixture, it is recommended to thoroughly clean and dry the neck of the canister and the area around it in order to avoid the ingress of impurities: dust, water, etc. The same is done with the tank before filling the fuel: the lid and neck are cleaned of dust and adhering dirt, so that it does not get into the gas tank, and then into the engine.

Gasoline and trimmer oil proportions Calm

The German manufacturer of high-quality cutting tools Stihl, in addition to chainsaws, produces motor mowers. It is an indispensable tool for mowing grass and lawn trimming with ease and mobility.

The brushcutter, or trimmer, also has a two-stroke engine and is fueled with a fuel mixture. For the Stihl trimmer, a ratio of 1:50 is recommended (for 5 liters of gasoline, 100 ml of oil).

Oil selection

Unlike four-stroke engines, Stihl 180 chainsaw oil is poured directly into the gas tank, after having been mixed with gasoline. It is recommended to fill the chainsaw with the oil specified in the instructions for this model.

Chainsaw Basics: Fuel and Oil

Under no circumstances should you use oil intended for low-speed engines (boats, scooters, etc.).

It can significantly reduce the life of the engine, and if traces of such a substance are found in the cylinder-piston group, the tool will be considered withdrawn from the warranty, that is, it will not be subject to warranty repair or exchange.

Stihl synthetic and mineral oils for chainsaws are sold in bottles or cans of different capacities: from 100 ml to 5 liters. Mineral ones have a lower cost, while semi-synthetic and synthetic ones ensure complete combustion during engine operation, i.e. no carbon deposits and a minimum of toxic compounds in the exhaust.

In addition, synthetic oils retain their properties over a much wider temperature range, and also contain special additives that are useful for engine operation: antioxidant, detergent, preservative, etc.

So with a small estimated volume of work, you can not buy a bulk canister, but limit yourself to a bottle. Only Stihl mineral greases do not have an expiration date.

Gasoline selection

The first question that the user faces before starting work is what gasoline to pour into the Stihl chainsaw.

Gasoline for the Stihl chainsaw is filled exclusively with unleaded high-octane gasoline, that is, with an octane number higher than 90. If you fill it with a low-octane gasoline, it is fraught with engine overheating, piston seizure and engine failure. Therefore, it is optimal to pour AI-92 or AI-95 gasoline into the chainsaw, but here the question of fuel quality arises.

Poor-quality AI-92 may “fall short” of the declared octane number, and AI-95 often contains many additives that do not bring any benefit to the engine. In addition, if the additives are of poor quality, they do not last long, and after a few days the purchased fuel can turn into a low-octane fuel, which is not suitable for a chainsaw engine.

At the same time, a good 95 can harm the piston system. “burn” it. Thus, some users found a way out: to refuel the chainsaw with AI-92 gasoline mixed with AI-95. This achieves an optimal balance between octane number and the amount of additives.

Calm oil

Stihl produces its own oil for its tools. High-quality oil Calm for 2-stroke engines has a high lubricity.

Consider the table of the assortment of oils for chainsaws from the official site of Stihl.

Here we see two types of motor oils:

  • HP
  • mineral base,
  • has a shelf life of 4 years,
  • minimum application temperature:.10 ° C
  • available in volumes from 20 ml to 55 l.
  • HPUltra
  • synthetic,
  • has a shelf life of 4 years,
  • burns out completely in the piston group,
  • biologically safe and degrades more than 80% in 21 days,
  • low smoke,
  • minimum application temperature:.25 ° C
  • available in 100 ml and 1 l volumes.

The manufacturer also suggests in the description for lubricants how to dilute the mixture for refueling the saw. in a ratio of 1:50.

What gasoline and oil is better to choose for refueling a chainsaw Calm: a table of ratios, how to breed, proportions

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

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

Useful Tips

When calculating the proportions, remember that it is better to pour oil a little than to save on it: only a significant excess of lubricant is dangerous with the formation of carbon deposits, and a slight excess will not harm the engine. If you do not fill it, the consequences can be more dangerous.

When mixing fuel for the Stihl chainsaw, the manufacturer recommends first pouring oil into the canister, then adding gasoline and then vigorously stirring the components. But the practice of use shows that the oil can “stick” to the walls of the canister and mix poorly, so it is better to carefully pour the oil into the gasoline and mix.

It is better not to leave the remains of the fuel mixture in the tank in order to prolong the life of the rubber seals and other parts susceptible to chemical damage. After stopping the saw, the fuel must be drained and disposed of: during long storage (more than a month), the octane number and other physicochemical properties of the mixture decrease and it becomes unsuitable for safe use.

In addition, after emptying the gas tank, you need to start the saw engine and let it run at idle speed until it stops on its own. this will mean that the carburetor is also rid of the remaining fuel mixture.

It is important to remember that the long-term performance of the equipment is largely dependent on the user. Saving on fuel in the case of a chainsaw can be much more expensive in the future. by out-of-warranty repairs of a broken saw or by purchasing a new unit. Compliance with the manufacturer’s instructions in most cases helps to understand the principles of the device and prolong its trouble-free and trouble-free operation.

How to Mix Fuel for a Husqvarna Two Stroke Engine Chainsaw

Storage advice

It is better to prepare the mixture in an amount that should be enough for one-time work. The problem lies in the irreversible deterioration of the working properties of the mixture during storage. The finished composition is recommended to be used over the next few days.

A mixture of gasoline with a month-old oil impairs the traction capabilities of the engine. There is also the formation of resinous compounds in the fuel system and intense carbon formation in the combustion chamber, loss of mobility of the piston rings.

  • With minimal damage to quality, it is advisable to store gasoline with oil for no more than 2 weeks. At an ambient temperature of 25 degrees Celsius or more, this period is reduced to 8-10 days.
  • In order to save money, the expired mixture can be gradually consumed by mixing it into the fresh composition in an amount of no more than 10% of the total volume.

In order to avoid problems associated with the failure of the fuel system, it is recommended to filter the prepared mixture through a non-fiber material such as suede, or a fine-mesh twill weave, a metal mesh.

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 the saving of 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.

Benefits of branded oils

Many domestic and foreign manufacturers specialize in the production of special motor oils, but the highest rating indicators are for the branded products Shtil, Huskvarna and Makita.

Only in certain parameters are the domestic motor oils of the Lukoil trademark inferior to the branded assortment.

The list of advantages of branded motor oils includes:

  • economical consumption;
  • stability of performance under difficult operating conditions and during long-term storage;
  • minimum amount of toxic compounds in exhaust gases;
  • almost complete absence of carbon deposits.

According to the American classification, API-TB oils can be used for work in household and professional models. The Japanese counterpart is JASO-FB and JASO FD. Preparation of a combustible mixture using oil for 4-stroke engines is strictly excluded.

Red, green or any other color of oil determines the product’s belonging to the assortment of a certain manufacturer, therefore, when determining the characteristics of the material, it is not taken into account. Be extremely careful when choosing a motor oil of unknown composition and origin.

Until you receive additional information about the quality and operational parameters, it is better to temporarily refuse to use such material.

It is allowed to mix motor oils of the same type in composition and purpose, produced by brands known for the quality of their assortment. Under no circumstances is it allowed to mix mineral and synthetic oils.

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.

Dosage of oil in the Chinese version

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

The doubled consumption of engine oil is compensated by its lower cost. According to the developers, original components are introduced into the composition of Chinese oils, contributing to the increase in the durability of power units and the real extension of their assigned resource.

According to the conclusion of independent experts, the quality of the best brands of Chinese motor lubricants corresponds to those of European manufacturers in the middle price range. This is the level of branded motor oils of the Standard group and partially. Super.

The ratio of gasoline to chainsaw oil

Household and professional chainsaws are powered by two-stroke internal combustion engines running on a metered mixture of gasoline and engine oil adapted to the difficult operating conditions. The correct proportions of oil and gasoline for a chainsaw are one of the important conditions for stable traction characteristics of the engine and low-cost development of its assigned resource.

The need to obtain a sufficiently high power from a small-cube power unit makes it necessary to operate chainsaw engines at high-speed modes, therefore, increased requirements are imposed on the quality of both components of the fuel mixture.

Caution. fake!

Small private companies from China and other Asian countries specialize in the production of motor oils, which are sold at a lower cost in the markets under the trademarks of leading manufacturers.

  • The characteristics of counterfeit products are an order of magnitude lower than the original ones. The constant use of counterfeit products adversely affects the operation of the chainsaw and the durability of its operation.
  • Only an experienced specialist can determine the status and quality of the oil, therefore, you can avoid possible risks by buying consumable components in a network of branded and licensed retail outlets.
  • The use of substandard lubricants for service specialists is a legal basis for depriving the owner of a faulty saw of warranty repair and restoration obligations.

Self-selection criteria

A large assortment allows you to choose an oil that fully corresponds to the class and characteristics of the chainsaw, the conditions of its subsequent operation.

  • For budget models, you can use oils of the Standard category, for professional chainsaws, consumable lubricants of the Super and Ultra categories are recommended.
