How to dilute stihl oil per liter. Proportions for Swedish chainsawsopil Husqvarna

The proportion of oil and gasoline for the chainsaw “STIHL”: types of oil, selection of gasoline and proper mixing

Many users of the benzo tool relate to the preparation of the fuel mixture quite irresponsible. For example, I met the owners of the saw who diluted gasoline with oil “by eye”. They just poured as much as they want, and then came to me with a faulty tool.

It is important to understand that more, as less, does not mean better. It is the golden mean that is important.

If you prepare a mixture with a shortage of oil, then everything is clear. There will be a sufficient amount of lubrication for the cylinder and bearings, which means friction and temperature will increase, bunks are formed in the cylinder and can jam the crankshaft bearings.

And what will happen if you pour? A large volume of oil, during combustion, form a lot of residual combustion products that settled on the piston, in the exhaust window of the cylinder and muffler, making the movement of exhaust gases. As a result, a drop in power or complete loss of performance.

Freight that is formed with an excessive proportion of oil can settle under compression rings, preventing them from compensating the temperature expansion, which will entail bulletin, in general the consequences can be quite serious.

The device of the lubrication system

Depending on the brand of the chainsaw, the details of the lubricant can differ a little structurally, but their total number and connection scheme remains unchanged. The main components of the details of the lubrication system are:

    Oil tank located, as a rule, in the engine crankcase.

Fuel and lubricants

Petrol

Engine manufacturers recommend the use of high-octane gasoline of the AI-92, 95 brand. The use of fuel with various additives to increase the octane number is not allowed. During this time, the process of resounding and polymerization can take place in it, which negatively affects the operation of the engine.

We do not recommend consuming gas stored for more than 60 days

Most chainsaw engines provide for the use of ethyl gasoline. If you purchased a tool with a catalyst (the tank cover will be green) we recommend that unequilled brands of gasoline.

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

Oil

In the design of two.stroke engines with air cooling, a separate lubrication system is not provided structurally. Lubrication of moving parts occurs with oil available in the fuel mixture. Therefore, it is necessary to use only high.quality oils from trusted manufacturers.

Recommended oils for gas station refueling:

  • STIHL HP. designed specifically for chainsaw engines. It has proven itself under any weather conditions, provides ideal engine operation.
  • Husqvarna HP. oil from the famous manufacturer of garden technology. Special additives reduce the pale formation on the engine crankcase, which can occur due to the use of low-quality fuel.
  • Oleo-Mac Prosint 2T-multifunctional oil with synthetic esters. Protects the engine details from corrosion, reduces the wear of mechanisms and parts.
  • Champion Jaso FD. high.quality oil from a well.known company. Provides good protection of all moving engine parts;
  • Vitals Semisynthetic. all.season oil for budget models of chainsaws, intended for use at temperatures from.20 to 40C 0.

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

The choice of oil

Unlike four.stroke engines, STIHL 180 chainsaw oil is poured directly into the gas tank, having previously mixed with gasoline. It is recommended to pour the oil specified in the instructions for this model in the chainsaw.

In no case can you use oil intended for low.speed engines (boats, scooters, etc. D.).

It can significantly reduce the life of the motor, and if traces of such a substance in the cylinder-piston group are detected, the tool will be considered removed from the guarantee, t. e. will not be subject to warranty repair or exchange.

Synthetic and mineral oil oils for chainsaws STIHL are sold in bottles or cans of different containers: from 100 ml to 5 liters. Minerals have a lower cost, and semi.synthetic and synthetic provide complete combustion in the process of engine operation, t. e. lack of soot and a minimum of toxic compounds in the exhaust.

In addition, synthetic oils retain their qualities in a much wider temperature range, as well as contain special additives that are useful for engine operation: anti.orally, detergents, cannibal, etc. D.

You can choose motor oil for your tasks depending on the model of the saw 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 small alleged volumes of work, you can not buy a voluminous canister, but limit yourself to a bottle. The expiration date does not have only mineral lubricants of Stihl.

We make a mixture: important proportions

When using a two.stroke engine, pure fuel is purchased separately and mixed with oil, often in 1:50 proportions. In such a engine, it is constructively impossible to install an oil pump, so it is strictly prohibited from pouring pure gasoline in a chainsaw! Proportions, quantity and some brands manufacturer indicates in the instructions for the operation.

Important points in the preparation process:

  • Domestic chainsaws work with M8-V oil, M-12TPU, M8-V, TP, MGD-14M. In some cases, you can use foreign options;
  • Proportions: 2.5 l of gasoline FI-80 per 100 grams of oil;
  • Foreign models have a minimum fuel consumption. They work on foreign oils, and their proportions become 1:40 or 1:50.

Advantages and disadvantages of oil

Any high.quality machine oil has its advantages and disadvantages of any high.quality machine oil have their pros and cons of. Some experts say that any chainsaw oil is suitable for any. This is not entirely true, almost any substance can be used for Hursstavna chainsaw, but only transmission oil is required for the StiHL chainsaw. When choosing, you need to know the Oil Cauline, a two.stroke engine requires a composition that has a reddish, bluish or greenish tide.

To make a mixture yourself, it is required to use heat.resistant lubricant, which has a well.known trademark.

The seasonality affects the density of the product:

What are the features of different oils, you can find out carefully by studying the label on the container. In the absence of instructions or labels on the package, you should refuse to use such a substance. At the same time, the TTX of the oil should not radically change when the temperature modes are dropped.

The specificity of the lubricant is that it is optimal for high speed engines, which have air cooling. It is such power plants that are equipped with chainsaws. Mineral oils have a reddish tint, and “synthetics” has a greenish tint.

You should not use any substitutes, often among them are counterfeit products (up to 20%). It is quite difficult to distinguish a fake, it is required to have specially equipment.

It is recommended to store fuel in metal containers. It is best to cook the fuel mixture in the canister.

There are a large number of oils and each has its own characteristics

The consistency is made in the ratio:

There are almost completely no chainsaws on the market, which function on the mixture in a ratio of 25: 1. After pouring a new mixture, the tool should work for a while at idle.

TTX of mineral or organic oil intended for the chain itself are not suitable for preparing the fuel mixture. The reservoir (up to half) is filled with the finished product, then mixed (the container must be hermetically closed). Thus, a uniform composition is obtained. It is better not to cook fuel ahead of time, it quickly loses its functional properties. At room temperature, the combustible liquid deteriorates for two weeks.

The choice of oil

Unlike four.stroke engines, STIHL 180 chainsaw oil is poured directly into the gas tank, having previously mixed with gasoline. It is recommended to pour the oil specified in the instructions for this model in the chainsaw.

In no case can you use oil intended for low.speed engines (boats, scooters, etc. D.).

It can significantly reduce the life of the motor, and if traces of such a substance in the cylinder-piston group are detected, the tool will be considered removed from the guarantee, t. e. will not be subject to warranty repair or exchange.

Synthetic and mineral oil oils for chainsaws STIHL are sold in bottles or cans of different containers: from 100 ml to 5 liters. Minerals have a lower cost, and semi.synthetic and synthetic provide complete combustion in the process of engine operation, t. e. lack of soot and a minimum of toxic compounds in the exhaust.

In addition, synthetic oils retain their qualities in a much wider temperature range, as well as contain special additives that are useful for engine operation: anti.orally, detergents, cannibal, etc. D.

You can choose motor oil for your tasks depending on the model of the saw 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 small alleged volumes of work, you can not buy a voluminous canister, but limit yourself to a bottle. The expiration date does not have only mineral lubricants of Stihl.

How to breed

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

It is necessary to dilute gasoline for the Stihl chainsaw in a separate canister, in no case, without filling the saw in the gas tank of the saw separately. There are no oil pump and the possibility of installing it in these engines, so only the finished fuel is poured into the tank. There are even special canists with two necks on sale to make it more convenient to dilute the mixture, but you can add oil to gasoline for a chainsaw and in an ordinary canister.

The proportions of the gas station refueling are best observed as accurately as possible: the excess oil will create soot on candles and pistons and provoke detonation when fuel combustion. This can reduce the engine operating resource. In addition, the user of the saw in this case is forced to inhale exhaust gases with unburned fractions. At the same time, an excess of gasoline can damage the pistons due to insufficient lubrication.

Stihl Hp Ultra,Hp Super,Hp testing the smoke quality.( testul uleiurilor de la Stihl in 3 motocoase)

To dilute gasoline, it is recommended to use special tools. this is a measured container for gasoline, a lubricant dispenser, a syringe, a canister for the preparation of the mixture and a watering can for refueling the sawdaulu a tank. All these auxiliary accessories are sold in official stores and at Stihl dealers.

Some people’s craftsmen are advised to use a plastic bottle in case of lack of special measuring accessories: a full cover (from the same bottle) is poured into a half-liter container filled with gasoline. The output is an approximate ratio of 1:50.

The amount of the mixture for refueling is best calculated in advance based on the estimated 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 spend about 1.2 liters per hour of operation (more accurate descriptions of the saw can be seen in the instructions). Thus, it makes no sense to prepare a mixture in volumes exceeding 3 in a row.

Before the start of preparing the mixture, it is recommended to carefully clean and dry the neck of the canistra and the area around it to avoid the hit of extraneous impurities: dust, water, etc. D. The same is done with the tank before pouring 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.

Stihl chainsaw oil

STIHL chainsaw motor oil today is universally recognized as the best option for this technique. And this is logical. No one better than the saw manufacturer knows what properties the lubricants should have to create the most favorable operating conditions.

STIHL for gasoline saws produced several types of oil. Two options are common.

Synthetic Stihl HP Ultra

Greenish lubricant. It has very good bioference properties. Contains a minimum amount of sulfur and other inclusions that can potentially form soot.

It mixes perfectly with gasoline and is capable of not precipitation for a long time for a long time. This property is especially useful if the saw is not used daily, since there is no need to drain fuel.

Mineral Stihl HP

It has a red tint. Does not have the properties of biological decomposition. In this oil, it is extremely not recommended to operate a chainsaw in a closed room.

The lubricant mixes well with gasoline. However, with prolonged simple, it is recommended to completely drain the fuel from the tank, since in a diluted state the properties of the oil gradually fall.

Even with prolonged operation of the saw on the mineral lubrication of the STIHL, the carpet on the piston skirt, cylinder and candle is minimal. This lubricant material is relatively cheap and is most popular in the Husqvarna chainsaw

, which is also a large manufacturer of chainsaws, produces its own set of lubricants for its technique. Husqvarna’s motor oil for the chainsaw today is officially supplied in only one form: Husqvarna hp.

Husqvarna HP gasoline oil is a semi.synthetic product that fully meets all the requirements in full

This lubricant goes well with the technique. but can be successfully used in saws from other manufacturers. Has excellent lubricant qualities, does not leave raids on the details of the cylinder.piston group.

The proportion of gasoline and oil for chainsaw Husqvarna is similar to the proportions for the STIHL technique and is 50: 1.

How to dilute the oil for the Husqvarna chainsaw and not be mistaken if there is no dispenser on kanistra with the products of this company? Here, all owners of gasoline saws are recommended to acquire a measuring capacity with a price of division of 1 ml.

The fact is that it will equally negatively affect the resource of the piston group of a two.stroke engine lack and an excess of lubrication. The lack of piston wear will accelerate from the deficiency.

On the piston and cylinder may appear bullying and furrows. An excess can lead to the formation of deposits and increased smoke, the service life of the candle will be reduced.

What lubricant liquid to use for Husqvarna, if there is no way to purchase the original? The answer is simple: any with similar properties. STIHL products is also suitable.

Other lubricants

There are two more well.known manufacturers of chainsaws, the products of which occupy a considerable market share in this Makita and Patriot. Motor oil for chainsaws of these manufacturers is also produced under their own brands.

What oil for the makita chainsaw oil? Ideally, of course, the original from the same manufacturer. Lubricants manufactured under the Makita brand have a balanced set of qualities and a relatively low price among such branded products.

What oil for the Patriot chainsaw oil? There are also branded lubricants here. It is best to use them. And these oils are produced in several versions.

The line of company products also contain lubricants for chains. Lubrices for the chainsaws of the Patriot brand have proven themselves well. And today they are often used as alternatives and in another technique.

From domestic products, 2-stroke oil “LUKOIL” is pronounced brightly. At a low cost, this product has really impressive properties.

After its use in most cases, soot is not formed in the combustion chamber. LUKOIL oil mixes perfectly and has good lubricating and protective properties.

It is also worth noting such an immortal option as ordinary M8 motor oil. Despite the great abundance of specialized lubricants, many owners of the chainsaws use it in the old fashioned way.

This option is permissible in the short term and only for easy operating modes. But you need to be prepared for the appearance of heavy deposits, if you use motor lubricants on an ongoing basis.

In the industrial sphere, they cannot be used: it will greatly affect the saw resource. It is more reliable to use specialized lubricants.

Answers to frequently asked questions

We will briefly answer the most frequently asked the owners of the chainsaws.

Is it possible to pour car oil in a chainsaw?

Yes, you can. Once to perform simple tasks without serious loads. For example, we will present this situation.

Initially, no work was planned using a chainsaw. Therefore, specialized lubrication of 2t was not purchased in advance.

But upon arrival at the cottage, it was found that, for example, a tree fell on a fence. And it needs to be urgently divided and removed. In this case, you can use one.time lubricant.

How much oil is needed for a chainsaw in this case?

It is recommended to pour 30-50% more lubrication. The saw will smoke stronger, but the probability of piston damage will decrease. For example, it is better to take 2.5-3 grams of oil per 100 grams of gasoline. The main idea here is this: for a saw it is better inappropriate lubrication than without it at all.

Choose synthetics, semi.synthetics or mineral oil?

Here again it all depends on the type of saw and its constructive purpose, as well as the nature of the work. If the saw works in industry on the cut of thick logs or the processing of solid wood, and not at home (for household needs), in the long run, the use of synthetics or semi.synthetics may well be more profitable.

Oil selection rules for chainsaws and motorcycles. video

If the chainsaw is in domestic use, then an ordinary mineral water is quite suitable.

How to stir gasoline with butter?

The exact technology of the mixing procedure itself (not a proportion), which should be adhered to, does not exist. Usually an empty container with a measured scale is taken, gasoline is poured into it.

For example, 1 liter. After adding a lubricant is added. A syringe or a measured glass with a price of division of 1 ml is used for a fence of the necessary portion of lubrication. The mixture is thoroughly mixed and poured into the saw.

It is not recommended such a method as breeding oil with gasoline immediately in the fuel tank of braids for grass. Especially if the tank was completely dry before. Immediately after pouring into the tank, gasoline will fall into the fuel line without oil.

That is, after the oil is added, all the same, some time after starting the saw will work without lubrication. And this one is just at the time of starting and warming up, when the engine is required most.

What oil is the best oil for gasoline?

There is no unequivocal answer to this question. It all depends on the design features of the chainsaw and its operation mode. In any case, a win.win option would be the purchase of corporate oil from a saw manufacturer.

In general, the trend is this: the more lubricating the liquid is more expensive, the more reliably it protects the engine from wear and forms less deposits in the cylinder.

Today on sale you can find fake gas oil oils, which, at best, are a tinted vice.

Therefore, to buy two.stroke lubricants, especially branded, which are so fond of fake counterfeit manufacturers, is better in large authoritative networks.

The probability of buying a fake in large specialized stores is minimal. Such points of sale value their reputation and almost never contact fake products.

We need high.quality components

Practice proves the influence of the quality of the prepared mixture, taking into account the necessary proportions on the operational period of use of the tool, power, performance:

  • It is not recommended to use the components that have completed the shelf life.
  • It is especially important for the components of gasoline and oil. not to use the components obtained on the basis of gas condensates, since the molecular structure contains harmful, for ICEs, rush and water and water.
  • Partial discrepancy between AI-92 international standards. AI-95 brand is saturated with additives that extinguish the detonation moments.

The noted deficiencies limit in time the operational resource of manual chainsaws, the ICE of which work at complex consistency of the combustible mixture.

Why should the proportion of gasoline and oil should be observed?

Many buyers, when purchasing a chainsaw, are perplexed why, in the gasoline oil recommended by the manufacturer, added in the exact amount. It’s all about the intricacies of a two-stroke engine, which differs from a 4-stroke counterpart near a number of specific design solutions.

One of them: the manufacture of a single.cylinder engine in which there is no crankcase for filling lubricants. This is seen by the technological luck of its time.

You can imagine how the incoming combustible mixture loses the molecules of oil settling on the stacks of the cylinder. In the future, it creates a sliding protective film in the rubbing nodes and DIC details, reducing the physical contact of the piston rings with the wall of the cylinder, connecting rod and crankshaft.

Provide the unit maximum performance, long.term operational regime is achieved by the correct ratio of pure gasoline with recommended oil. Violation of the rule guarantees the quick exit of the tool from a functional state. DIS breakdown will require significant funds for repair or replacement with a new analogue.

Many users of manual mechanized tools present in the unit are considered a tank for lubrication and power plant. It is fundamentally wrong. Lubrication is designed for the chain during operation. But only. The oil capacity of a priori is not connected by a pipeline with the engine.

We serve a two.stroke trimmer for grass

For a two.stroke engine, the main operation of maintenance is the maintenance of the air filter. The frequency is 10 hours of work. When cleaning, the material in warm soap water is washed. Before installing back, the surface is slightly impregnated with oil.

At the same time, check the cleanliness of the fuel filter (if any). However, it is better to clean the fuel mixture when refueling a trimmer for grass. The spark plug is checked regularly for the formation. The gap between the electrodes should be 0.5 mm.

With regular care and proper operation, a trimmer for grass will last many years.

The choice of oil

Unlike four.stroke engines, STIHL 180 chainsaw oil is poured directly into the gas tank, having previously mixed with gasoline. It is recommended to pour the oil specified in the instructions for this model in the chainsaw.

In no case can you use oil intended for low.speed engines (boats, scooters, etc. D.).

It can significantly reduce the life of the motor, and if traces of such a substance in the cylinder-piston group are detected, the tool will be considered removed from the guarantee, t. e. will not be subject to warranty repair or exchange.

Synthetic and mineral oil oils for chainsaws STIHL are sold in bottles or cans of different containers: from 100 ml to 5 liters. Minerals have a lower cost, and semi.synthetic and synthetic provide complete combustion in the process of engine operation, t. e. lack of soot and a minimum of toxic compounds in the exhaust.

In addition, synthetic oils retain their qualities in a much wider temperature range, as well as contain special additives that are useful for engine operation: anti.orally, detergents, cannibal, etc. D.

You can choose motor oil for your tasks depending on the model of the saw 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 small alleged volumes of work, you can not buy a voluminous canister, but limit yourself to a bottle. The expiration date does not have only mineral lubricants of Stihl.

Preparation of fuel mixture for a chainsaw

Petrol

Gasoline should be with an octane number no less than AI92. You can also fill in AI95, but its quality at our gas station leaves much to be desired, so if you are not sure of the 95th, it is better to take gasoline AI92 gasoline to dilute gasoline into a chainsaw. You should not take gasoline in the same way for a long time in the canister, tank or any other capacity. Gasoline for the preparation of the fuel mixture in the chainsaw should be fresh, otherwise it loses its properties, in particular the octane number, and even if you run the chainsaw on such fuel, it will not give out full power. And the saddest thing in this case is that the failure of the chainsaw due to poor.quality fuel is considered a non.warranty occasion 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 American Petroleum Institute (API) classification, the American Oil Institute has an API-TB class, there are also API-TC oil oils, but they are designed to work with less loads than most of the chainsups we common. If we take the classification class of Japan Automobile Standards Organization (JASO) Japanese standardization organization in the field of automotive industry, then focus on JASO-FB and JASO FD classes (see.Table 1 below.).Not in any case do not use oil for four.stroke engines! Remember that in a two.stroke engine the oil should be completely burned, which means it is better to take synthetic oil, since it gives less smoke and burning residues. And if you pour oil for four.stroke engines in your chainsaw, which will not burn completely and as a result of the fog, then you will fail. The best thing to be guided by when choosing oil for a chainsaw is an instruction for her.

Proportions

When preparing a fuel mixture of gasoline and oil for a chainsaw, be sure to see the manufacturer’s recommendations. Why is it so important to observe these recommended proportions? With a small amount of oil in gasoline, the cylinder and the piston will occur and the bulletin will occur, and this is the exit of the CPG and repair. If there is a lot of oils in gasoline, then this is a dozen and the failure again.Each manufacturer has its own recommendations on proportions (see.Table 2 below). Try not to store the finished mixture longer than a month. Do not store it under direct sunlight and openly. Avoid water and dust, this will lead to the failure of the carburetor, since the fuel filter is often not able to completely clean the fuel.

Since they often come from search engines at the request of the same “how much oil is pouring 1.2.5 liters of gasoline”, then I add another table under which you can find out how much oil to gasoline according to the accepted proportions. The proportions can be viewed in table 2 or, more precisely in the instructions for your chainsaw.

Fuel mixture dilution devices

Of course you can use a canister, a syringe or a measured bottle, but there are more convenient options. It is worth noting that, for example, STIHL oils are produced in 2 types of packaging- with a dispenser and without. With a small price difference, a bottle with a dispenser greatly facilitates the process of making the mixture. There are also many different cans with a dispenser, with departments for oil and gasoline separately. All these devices reduce the period of preparation for the launch and work of the chainsaw.

STIHL canister with oil and gasoline departments

This canister has two departments for storing oil and gasoline separately. A capacity of gasoline with a volume of 5 liters, and the oil container has a volume of 3 liters. Often, many owners of a benzo.tool with two.stroke engines in this canister carry oil in the same department, and in the other a ready.made fuel mixture.

Husqvarna canister with oil and fuel mixture departments.

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

How to breed properly?

The figures of breeding proportions are not in vain given with such accuracy. That is, it is not said that “take about such and such an amount of oil”. Do not observe the exact proportion by eye, so you have to use something that will allow you to measure the exact amount of oil and gasoline.

Complete with some inexpensive chainsaws are usually a measured tank with risks. As a rule, it has several scales for different proportions. Or one, if the manufacturer implies that this tank will only be used with a saw with which it comes in the kit. There should be two horizontal risks on this scale. The lower one shows the level to which gasoline needs to be poured. Upper. level to which the mixture should reach after adding oil to gasoline.

For more accurate measurement of oil, you can use a medical syringe. Preferably at least 20 ml.

In general, pour gasoline into a measured container, add the desired amount of oil measured with a syringe and shake.

The preparation of the mixture must be done in a separate container, and not directly in the tank of the chainsaw. Otherwise, the oil, not having time to dilute with gasoline, can get into the carburetor, which will complicate the factory, up to the need to remove the carburetor and its cleaning.
