How To Properly Dilute Gasoline For A Chainsaw

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 capable of providing 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 gets into the cylinder together with small particles, they will leave their mark in the form of accelerated wear of the piston rings.
  • Generation of a large amount of black smoke, which indicates burning oil

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

Using the instructions, you can independently prepare the correct fuel mixture on which the chainsaw will work. Improper dilution of the fuel mixture will not only reduce tool life, but also reduce tool performance.

For imported chainsaws, the following oils are recommended:

How To Properly Dilute Gasoline For A Chainsaw

  • Classification of TA, TB and TC (TSC-1/2/3) by American API standard.
  • 2t oil for chainsaws of the Japanese JASO standard, corresponding to classes FA, FB and FC;
  • Oil of European standard ISO, EGB and EGC grade.

As for domestic chainsaws, high-quality oil is also recommended for them. If it is not possible to purchase it, then you can use a grease intended for 2-stroke motorcycle engines.

Choosing oil for chain saw chain lubrication

In addition to the motor, the chainsaw has another important unit with many moving parts. the chain. It does NOT use engine oil, but chain oil for a chainsaw. it is cheaper and has completely different properties.

Which chain oil to use depends on its “age”. If your chainsaw is new and is under warranty, you will have to use ONLY branded oils Recommended by the manufacturer. Otherwise, if the saw fails, the service center will immediately remove it from the warranty, because The use of lubricants that do not meet the manufacturer’s requirements is a violation of the operating conditions. On the other hand, branded oils are really high quality:

  • Allow to work in a wide temperature range from 30 to 50 С,
  • High adhesion improves the “adhesion” of the oil to the chain and reduces its consumption;
  • Additives reduce friction and extend chain life.

If the saw is out of warranty and buying a branded chain saw oil is NOT within budget, you can use any gear or engine oil. It is advisable to change it 2 times a year: in winter use a thinner oil, in summer. thicker.

What oil to lubricate the chainsaw chain also depends on the wood with which you will have to work. For dry wood, gear oil is recommended, for wet wood it is better to use some kind of diesel engine oil.

Benefits of branded oils

Many domestic and foreign manufacturers specialize in the production of Special motor oils, but the highest ratings are in the branded products of Stihl, Husqvarna and Makita.

Domestic engine oils of the LUKOIL brand are inferior only in certain parameters of the branded assortment.

→ HUSQVARNA at the best PRICE In the list of advantages of branded motor oils:

  • Economical consumption;
  • Stability of performance under difficult operating conditions and during long-term storage;
  • The 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. You should be extremely careful when choosing engine oil of unknown composition and origin.

To obtain additional information on quality and operational parameters, it is better to temporarily refuse to use such material.

It is allowed to mix engine 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.

The ratio of the amount of oil and gasoline for the fuel mixture

The proportion of oil and gasoline for a chainsaw is usually made up according to two recipes:

  • 50 servings of gasoline per serving of engine oil
  • 40 servings of gasoline per serving of engine oil

If the chainsaw was recently purchased and has NOT yet been operated, then the fate of the lubricant is increased by a quarter. The same amount is poured into fuel when cutting at temperatures below 2 degrees.

It is NOT difficult to get such a mixture. Almost every modern saw is equipped with a special two-section container. Oil is poured into a smaller part of it, and gasoline is poured into a larger part. The lids of both parts are tightly twisted and the container is turned over, shaken thoroughly. This achieves a complete and homogeneous mixing of both components.

If there is such a special container, then you can use any gasoline-resistant plastic container with a one liter lid and a disposable syringe for 5-10 cubes. The gasoline tank must first be cleaned of various pollutants and water. After that, one liter of 92-95 gasoline is poured into it.

In parallel, 20 ml of oil is drawn into the syringe. If filling is done in cold weather, then you need to take 24-30 ml. Gently pour it into a container with gasoline. It is tightly closed with a lid and shaken thoroughly until the components are completely mixed.

Fuel selection

Which fuel to choose for a chainsaw is a no-brainer, the success of the unit directly depends on it. According to the existing canons, good gasoline for a chainsaw is considered NOT leaded, but high-octane from a trusted manufacturer. The cleaner the fuel, the better. If gasoline has been stored in the Canister for a year or a year and a half, this will adversely affect the nature of the device’s operation, therefore, the substance should be prepared before the very start of work.

It is important to monitor that there is no alcohol in the fuel, any additives that can disrupt the functioning of the power plant. Experts are still debating which is better than 95 or 92. The first has more stable detonation rates, but most often the 92 is still used. The reason is simple: questions often arise by the 95th, there are a large number of various additives in it, which have a bad effect on the operation of the saw engine. Micro-knock (piston impulse in the opposite stroke) occurs, which occurs practically at every revolution of the crankshaft. If the octane number is even higher (98), then the micro impacts will become even more intense.

The consequences of improper gasoline on the quality of the unit can only be negative:

  • The mechanism will be difficult to start.
  • The power will be minimal.
  • Parts will wear more intensively.

Petrol

The main component of the fuel mixture for chainsaw engines is gasoline with an octane number of at least 92.

  • The opinions of experts on the use of different brands of gasoline are ambiguous. On the one hand, the incomplete compliance of domestic gasoline A-92 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 if you are fully confident 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.

There are also irreversible changes in the operating parameters of the fuel when it is stored for a sufficiently long time in a plastic container, regardless of the level of its petrol and oil resistance.

Why does oil flow from a chainsaw?

If you notice that oil is leaking from the chainsaw, then this is a malfunction and there may be several reasons for it:

  • Most often, oil flows from the chainsaw chain if the tightness of the fuel tank is broken. Examine the reservoir carefully for cracks or tightness of the tube to the fitting. If there are violations. eliminate them.
  • Clogged oil channels, with the result that oil does not enter them, but drips to the ground. It is required to clean the channels with pressure. this will eliminate the problem.

Instructions for refueling a chainsaw

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
  • Tool Place on a clean and level surface. Before unscrewing the gas cap, you need to clean or blow off sawdust, dust and dirt
  • Tank neck must point up
  • Install a small watering can in the neck, then pour fuel
  • I control the filling process, since 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 motor 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 to start a chainsaw engine, you can read in this material (link).

Chainsaw device

Each chainsaw has different technical data and can do different work.

Powerful saws are suitable for cutting down centuries-old trees, small-format chainsaws are more suitable for various jobs in the backyard:

  • Cutting tree branches
  • Harvesting firewood

Chainsaw standard blocks:

  • Power point.
  • Clutch.
  • Ignition block.
  • Carburetor.
  • Fuel block (oil and fuel tank).
  • Filters for cleaning incoming air.
  • Starter.
  • Chain.
  • Tire.
  • Chain brake.
  • Tension mechanism.
  • Chain lubrication element.

Each chainsaw requires high-quality fuels and lubricants, it is they who ensure the long-term productive operation of the unit. What gasoline for the chainsaw to fill, in what proportions?

Simple oils are suitable for domestic chainsaws, foreign chainsaws need more complex fuel mixtures, which have been thoroughly cleaned.

Advantages and disadvantages of oil

Any quality machine oil has its pros and cons

Any quality machine oil has its pros and cons. Some experts say that any chainsaw oil will work. This is not entirely true, almost any substance can be used for the Hurstavna chainsaw, but for the Stihl chainsaw, only gear oil is required. When choosing, you need to know the shade of the oil well, a two-stroke engine requires a composition, which has a reddish, bluish or greenish tint.

To prepare the mixture yourself, you need to use a heat-resistant grease, which has a well-known brand name.

Seasonality affects product density:

  • Air temperature.
  • Humidity.
  • Solar radiation intensity.
  • Pressure.

What are the features of different oils, you can find out precisely by carefully examining the label on the container. In the absence of instructions or labels on the packaging, you should refuse to use such a substance. At the same time, the performance characteristics of the oil should not change dramatically with a temperature difference.

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

It is recommended to store fuel in metal containers. Prepares fuel mixture best in Canister.

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

The consistency is done in the ratio:

The performance characteristics of mineral or organic oils intended for the chain itself are not suitable for preparing the fuel mixture. The finished product is poured into the tank (up to half), then mixed (the container must be hermetically closed). Thus, a homogeneous composition is obtained. Fuel is better not ready ahead of time, it loses its functional properties quickly enough. At room temperature, flammable liquid deteriorates within two weeks.

Instructions: How to properly dilute gasoline with chainsaw oil

Mineral oils are inexpensive, so they are most often used. Synthetic oils must be filled if there are significant temperature fluctuations, they do NOT generate carbon deposits, they have additives useful for dynamic nodes.

The product of the Husqvarna company is considered the highest quality, the second place is the Lukoil machine oil.

The advantages of THESE oils:

  • Low consumption.
  • Maintaining quality.
  • Ability to maintain technological properties for a long time.
  • Can work in extreme conditions.
  • No toxins.
  • Minimum amount of carbon deposits.

Many professional tools use a lubricant made using API-TB technology (USA). Also popular are products that are produced according to the JASO-FB method (Japan).

Let’s mix oils from different brand manufacturers with similar characteristics. Mineral and synthetic oils are incompatible. The best oil for household chainsaws is considered “Standard”, technical fluid “Ultra” is optimal for professional equipment.

Some oils can successfully replace each other. For example, substances Produced by Husqvarna and Stihl. Lubricant for scooter engines or motor boats Not suitable for chainsaws, the oil quality is poor. If the proportions of oil and gasoline are not maintained, the tool will quickly fail due to the abundant formation of carbon deposits.

How much oil is required to add to gasoline?

Types of oils used for dilution in gasoline

Chainsaws have oil pumps, so the combustible mixture alone cannot be used. You should carefully read the instructions that are attached by the manufacturer to each product. There is a lot of information on the Internet, it is NOT difficult to find it.

If there is no lubrication, the saw will fail after a short time. It is recommended to do preventive maintenance of the unit, fill in properly diluted fuel, in this case the tool will function for many years.

If we take, for example, a Husqvarna chainsaw, then unleaded gasoline with the first addition of grade 92 is suitable. If the composition has a greenish tint, this indicates that the product is a premium class. AI-92 is the optimal product, which can be suitable for such a device. On average, professionals advise adding 20 to 50 ml of machine oil per liter. If the power of the unit is one and a half kilowatts, then only 25-27 ml of oil is required.

How to dilute engine oil and gasoline, in what proportions? This question arises for all users. First you need to stock up on containers:

  • Measuring liter bottle
  • Dispenser and syringe
  • A watering can, which will allow you to pour the substance into the tank

The process of mixing oil and technological gasoline is simple. It is important to observe safety precautions so that static electricity does not accumulate, not a drop of water gets into the fuel.

Types of oils used for dilution in gasoline

What proportions should be done? The engines are mostly two-stroke, so the mixture is usually 1:50. Russian-made chainsaws function with products of the following brands:

  • M8-B
  • M-12TPU
  • TP
  • MGD-14M

For foreign analogues, it is permissible to use two liters of gasoline per 80 grams of oil. Foreign saws are distinguished by economical fuel consumption, the proportions of oil in them vary from 40 to 49 shares.

Oil shades can vary significantly, this should be taken into account during operation. For example, HP produces reddish engine oil. If the composition has a greenish (sometimes blue) tint, then this is a sure sign that the product is synthetic premium. The quality in such compositions is high, the price is also rather big.

What gasoline should you use for your chainsaw? How to breed it correctly?

The chainsaw is simple in design and is sometimes needed in private households. The device cannot work fully if you do not use the correct fuel mixture, which you should be able to prepare.

Advice

Tips and life hacks are extremely useful in practical work, consider some of them:

  • It is convenient to use canisters with dispensers, while experienced people filter gasoline through suede. The cleaner the fuel, the better the carburetor will work.
  • Gasoline can actively evaporate, especially at high temperatures, a suspension falls out at the bottom of the canister, which must not be poured into the engine.
  • Recommended fuel is ready for no more than three operational refueling.
  • The quality of the fuel can be affected by the material of the container, especially PVC materials react actively.
  • If the combustible mixture was poured of poor quality, the chainsaw may be removed from the warranty.
  • During operation, the tightness of containers and the rhythmic operation of the engine should be tested.
  • One of the first signs of a malfunction is an unnecessary heating of the circuit.
  • Before subjecting the tool to severe stress, it should be tested at idle speed.
  • The tank is enough when working for half an hour.
  • There is still grease (residues) in the second container when it has run out in the tank.
  • If a large amount of smoke is generated during operation, this means that the fuel is of poor quality.
  • During operation of the unit, do not approach open flames.
  • (Distance up to 2 meters).
  • Do not add fuel. “under the rim “, leave some space.

Fuel mixture: the proportion of oil and gasoline for the chainsaw

The chainsaw engine is the “heart” of the tool, so it is very important to use a properly prepared fuel mixture.

The fuel mixture for a chainsaw is prepared from two components. oil and gasoline. Chainsaws are equipped with two-stroke engines, so oil is not added to the lubrication system (as in a four-stroke engine), but directly to gasoline. At the same time, it is very important to observe the correct proportions of ingredients, of course, in no case should you try to work on pure gasoline, because in this way you will very quickly “kill” the chain saw.

If we talk about what kind of gasoline to pour into the chainsaw, then it will be optimal to use fuel with an octane rating of A-95, in this case the savings on fuel can turn out to be deplorable. Often European manufacturers indicate that it is possible to use A-90 or A-92 gasoline, but in the post-Soviet countries the quality of gasoline is inferior to European, therefore, in our realities it is better to use higher quality gasoline.

As for the proportion of the oil-oil mixture itself, everything is simple here: you must follow the instructions for the tool. All manufacturers of chainsaws indicate the required ratio in the instruction manual or in the passport of the tool, in addition, the proportions for refueling the chainsaw may differ depending on the model of the chain saw. As a rule, the proportion of oil and gasoline to a chainsaw of famous manufacturers is a ratio of 1:40 or 1:50, which means 1 part of oil for, for example, 40 parts of gasoline. Now arithmetic 1 liter of gasoline = 1000 ml of gasoline, divide by 40 and we get 25 ml of oil. If you do the same to a 1:50 ratio, you get 20 ml of oil per 1 liter of gasoline. As for budget chainsaws made in China, the situation is slightly different. The ratio of gasoline to chainsaw oil made in China 1:25, that is, divide 1000 ml of gasoline by 25, we get 40 ml of oil. The thing is that in branded chainsaws, a solid assembly and the distance between the pistons and cylinders in the engine is much less than in Chinese chainsaws, therefore the required amount of oil differs almost twice.

In order to measure the correct amount of oil, use a conventional medical syringe of sufficient volume.

Another subtlety. Fill the dry gas canister with gasoline first and then oil. The procedure, on the contrary, is fraught with a low quality fuel mixture, because the oil is denser, it will stick to the bottom of the canister. what a good mixing here.

Be sure to prepare the fuel mixture in the Canister and fill the ready-made special fuel into the gas tank! Never ready and DO NOT mix it directly in the fuel tank of your chainsaw!

If you figured out the question of how to breed gasoline for a chainsaw, then on storage conditions and shelf life of the fuel mixture it is worth saying a few words. It is best and easiest to prepare a petrol-oil mixture for 1 liter of gasoline, it is recommended to do this immediately before working with the tool. Chainsaw fuel tanks have a volume of 0.3 to 1 liter. In the conditions of domestic use, the entire volume of the prepared fuel mixture is rarely used in one session, so the remainder can be saved until the next session. It is necessary to store the fuel mixture in a special Canister for gasoline, in a dry, dark place. It is optimal to count that the shelf life of the finished mixture will be 7-10 days. The fact is that the oil on the market now is NOT synthetic, but organic, that is, natural. After 10 days, all lubricating properties are lost, gasoline simply “eats” the oil. Naturally, it is no longer possible to use such fuel, this can cause breakdown and failure of the chainsaw.

At the end of the work, it is necessary to drain the fuel mixture, start the chainsaw, the tool will stall (so that there is a dry carburetor in the saws) and now you can leave it in the next operation session.

Unsuitable fuel mixture must be disposed of.
