What Gasoline For Chainsaw

Gasoline for chainsaw: what to pour?

Since a two-stroke engine is used on chainsaws, where it is structurally impossible to install an oil pump, you cannot pour pure gasoline into a chainsaw! The chainsaws are filled with a fuel mixture of gasoline and oil. The proportions for different saws are set by the manufacturer, the specific number is indicated in the instruction manual.

The question is often asked: gasoline for a chainsaw. what to pour? I will try to answer in more detail.

Gasoline for chainsaw

For domestic chainsaws (Ural, Druzhba, etc.), AI-80 gasoline is used. Oils can be used domestically, such as M8-V (or early marking AS-8.10), M-12 TP, M-12TPU, MGD-14M. It is also possible to use oils from foreign manufacturers. In any case, the proportions when mixing oil and gasoline should be 1/25, that is, one hundred grams per two and a half liters of gasoline. For modern chainsaws from foreign manufacturers, the proportions are usually equal to 1/40 (100 grams per 4 liters of AI-92), 1/50 (100 grams per 5 liters of AI-92). Use AI-92 gasoline. You can often see that the AI-95 brand will be indicated in the instructions. But with our quality of this gasoline, the octane number of which is catching up with additives, I would not recommend using the 95th if you are not sure of its quality.

about mixing proportions:

To measure the required amount of oil, you can use a syringe, a measuring bottle, a special dispenser or, for example, a bottle with a dispenser from Stihl. Oils from different manufacturers in different colors. As you can see in the picture above, HP calm oil (mineral water) is red, more expensive synthetic ones are green. Husqvarna oil can be green or blue.

REMEMBER! IN THE CASE OF A CHAINSAW OUT OF THE SYSTEM FOR THE CAUSE OF FILLING WITH AN INCORRECT MIXTURE, THE REPAIR WILL BE NON-WARRANTY!

[important] Tips: It is better to overfill than underfill! If it is written 1/50, then when you pour 25 grams per liter, terrible will not happen, since coking in this case is unlikely. But if you add 15 grams per liter, it is quite possible that this will not be enough. Do not store the ready-made fuel mixture for more than a month (preferably less), as it loses its octane number (gasoline "runs out"). Run out the entire tank or drain before the season to avoid loss of gasoline quality and wear of rubber and plastic seals. Never use oils for mopeds. they are designed for lower rpm [/ important]

About refueling your chainsaw

Finally, about the procedure for refueling the Stihl MS180 chainsaw with a fuel mixture using a proprietary canister.

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

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

Chainsaw device

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

Powerful saws are suitable for felling centuries-old trees, small-format chainsaws are more suitable for various tasks in the home garden:

• 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 that ensure long-term productive operation of the unit. What gasoline for the chainsaw to fill, in what proportions?

For domestic chainsaws, simple oils are suitable, foreign chainsaws need more complex fuel mixtures that have been thoroughly cleaned.

Fuel selection

Which fuel to choose for a chainsaw is a no-brainer, the success of the unit directly depends on it. According to 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 starting work.

It is important to monitor that the fuel is free from alcohol, 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 indicators, but most often they still use the 92nd. The reason is simple: questions often arise by the 95th, it contains a large number of various additives that 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.

Instructions: How to properly dilute gasoline with chainsaw oil

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

The highest quality product is considered to be the product of Husqvarna, followed by Lukoil machine oil.

The advantages of these oils:

• Low consumption.
• Maintaining quality.
• Ability to maintain technological qualities 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). Products made according to the JASO-FB method (Japan) are also popular.

It is permissible to 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. Lubrication for scooter engines or motor boats is not suitable for chainsaws, the oil quality in them is low. If the proportions of oil and gasoline are not maintained, the tool will quickly fail due to the abundant formation of carbon deposits.

Advantages and disadvantages of oil

Any quality machine oil has its pros and cons.

Any quality lube 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 color of the oil well, a two-stroke engine requires a composition that 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 studying 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 difference in temperature conditions.

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. It is best to prepare the fuel mixture in a 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. It is better not to prepare fuel ahead of time, it loses its functional properties quickly enough. At room temperature, flammable liquid deteriorates within two weeks.

How much oil is required to add to gasoline?

Types of oils used for dilution in gasoline

Chainsaws do not have oil pumps, so 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 color, then this indicates that the product is a premium class. AI-92 is the optimal product that 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 gasoline is technologically simple. It is important to follow 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 of such compositions is high, the cost is also rather big.

Dirty gasoline

Some owners of chainsaws are sure that if the tool works in conditions of constant dust (there is even an air compensator in the carburetor in case of a clogged air filter), it means that it is capable of swallowing gasoline with pieces of rust, and working with small pieces of metal will go to lubricate the chain, so?

How much gasoline is stored

During long-term storage, gasoline evaporates (regardless of the brand), a sediment falls at the bottom, it loses its properties, in other words, it deteriorates. It is worth knowing that it is not the gasoline itself that ignites, but its vapors. Therefore, if there is a canister of gasoline in the garage since last year, then think whether it is worth it? Better leave it to light the BBQ fire.

The use of "stale" gasoline for a chainsaw entails many problems:

• Difficult start-up;
• Decrease in maximum power;
• Increased wear of chainsaw engine parts.

It is worth remembering that the prepared fuel mixture (gasoline with oil) is stored for no more than a month, after this time it should be disposed of. Using old mixture increases wear on the engine parts of the chainsaw. do not forget about it!

Octane number

This is where the fun begins. Can I refuel a chainsaw 95 with gasoline? In all operating instructions for chainsaws, manufacturers indicate in bold type: "Do not use gasoline with an octane rating above 92 for preparing the fuel mixture." It is understandable, but apparently not for everyone, because K. Chainsaws with a burned-out cylinder are brought to service centers from time to time!

Let’s figure out which gasoline is worth pouring into a chainsaw and which is not! For all two-stroke saw engines, you need to use 92 gasoline, this is what the tool is designed for. Filling 95 gasoline, the engine will begin to detonate (pushing the piston into the opposite direction), a kind of micro impact that will occur at almost every revolution of the crankshaft. About 98 gasoline, I think everything is clear, the effect will be even stronger, and it will already be mini strikes.

What gasoline to pour into a chainsaw

Everywhere and everywhere they write and discuss issues related to the choice of oil for a chainsaw, someone recommends only the original one, and someone “everything is fine” and on a regular Lukoil 2T! They also raise a lot of questions about mixing gasoline with oil. the process of preparing a fuel mixture for a chainsaw has any more or less human resource. But, no one ever raises the importance of the issue of using gasoline in a chainsaw! Why? After all, all technicians and engineers know how the use of high-octane gasoline affects engines designed to operate on low-octane ones! Chainsaw is no exception!

Summing up

In order for the chainsaw to serve for many years, never fill it with old gasoline, and you do not need to use grade 95 and even more than 98 gasoline to prepare the fuel mixture, only 92. Also, do not forget about the purity of gasoline. no odens!

I hope that now you are not wondering which gasoline for a chainsaw is suitable and which is not very.

Helpful hints:

• Sometimes it is better to pour a little oil than to regret it. If you give a little more oil than indicated in the instructions, then nothing terrible will happen. Carbon deposits are possible in cases of a large amount of oil and if the specified proportions are not observed;
• It is better to store the finished mixture for a month and no more, because for some reason it will lose its qualities;
• Correct shutdown. It is imperative to use or drain the contents of the tank, so you can extend the work of rubber and plastic seals;
• You should not use oil intended for mopeds for your chainsaw, because it is designed for low revs.

The correct operation of your equipment fully depends on yourself. First, do not disdain the manufacturers’ signs or, in extreme cases, the instructions on the oil packaging. This will help avoid unpleasant situations. The neighbor does not always know what is the best way to do it. The cheapness of oil and gasoline is not an indicator of high quality, because a breakdown of a tool can be much more expensive (about 80% of the cost of a chainsaw) than the funds saved on the fuel mixture.

What kind of gasoline should be poured into a chainsaw

Hello! Glad to see you again, dear readers and subscribers of Andrey Noak’s Blog. Everyone who has a chainsaw at home already knows exactly what kind of gasoline and how to fill it. But for those who just want to buy such a unit for themselves, the article will seem entertaining.

The chainsaw is one of the most convenient and versatile household appliances. Prepare the fuel mixture before use. But for the unit to work correctly, all the manufacturer’s recommendations must be followed. Each model is individual, so which gasoline to fill in the chainsaw?

Good to know

Procurement of fuel should be done counting on 3 refueling. After all, storing a large amount of fuel can negatively affect the operation of the chainsaw. The mixture can behave in different ways, as it will be influenced by many factors. As a result, your household unit may receive serious damage, which will entail financial costs.

Sometimes even the capacity can affect the quality of the liquid. Plastic and glass react with gasoline, which can create a flash fire hazard.

The finished liquid cannot be stored for more than a month, because the oxidation process takes place. After working with the chainsaw, you need to use up the remaining fuel, turn off the engine and remove the remaining fuel mixture.

Under the brand

For modern brands, for example, Husqvarna, Partner, Makita, Echo, Stihl, AI-92 gasoline is suitable. Today, just a colossal number of people complain about the premature failure of chainsaws due to poor gasoline. Therefore, some experts recommend pouring AI-95 into such chainsaws. At the same time, a good AI-95 can "burn the piston", and again, a certain number of people found a compromise and mix AI-95 with AI-92. In general, it all depends on the quality of gasoline and ultimately you decide.

For domestic instruments, Ural, Druzhba, it is recommended to take AI-80 gasoline. It is very important that fuel consumption is minimal.

Making the mixture: important proportions

When using a two-stroke engine, clean fuel is purchased separately and mixed with oil, often in proportions of 1:50. It is structurally impossible to install an oil pump in such an engine, therefore, pouring pure gasoline into the chainsaw is strictly prohibited! The proportions, quantity and some brands are indicated by the manufacturer in the instruction manual.

Important points in the cooking process:

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

Fuel mixture

To properly prepare fuel, you need a list of additional tools:

• Plastic or metal container for diluting the substance;
• Measuring bottle for gasoline;
• Dispenser;
• Syringe;
• Chainsaw tank filling can.

Some manufacturers, such as Stihl, immediately make measuring containers for more convenient measurement of the fuel mixture.

Different manufacturers produce oils in different shades. HP produces a red liquid. Green oil is a premium synthetic segment. For your Husqvarna chainsaw, you need to use the correct oil. It is high cost, good quality, and is green or blue.

To mix the components, you will need the aforementioned additional accessories. Also on sale you can find special canisters with two holes for oil and gasoline. Everything is very simple here, pour in the ingredients, tighten the lid tightly and mix by tilting the container. Glass and plastic bottles can be used.

The fuel mixture must be free from water or dust.

What gasoline to pour into a chainsaw?

When choosing a suitable fuel, each owner of the tool must start from the brand and country of origin of the model available on the farm. Old domestic saws called Ural and Druzhba are best filled with AI-80 gasoline. It contains exactly those additives that are necessary for the stable operation of unpretentious domestic engines. modern domestic models are designed to operate on 92nd gasoline.

Things are a little different with imported chainsaws. The engines of all these models are designed for more gentle fuel, therefore, German, Swedish, American and Japanese chainsaws must be refueled exclusively with gasoline, grade AI-92.

An important role in the choice of gasoline is played by its condition. Many novice gardeners are confident that fuel can be poured into the saw’s fuel tank, which will remain in the canister for a long time. Some believe that the tool already works in conditions of constant dust, and it is because of this that manufacturers have provided a special air compensator in the carburetor, which is triggered when the air filter is worn out.

This opinion is fundamentally wrong. As a result of a long stay in the canister, gasoline loses its main properties, and its composition, depending on the material of the container, is replenished with molecules of plastic or metal rust.

Due to a long stay in the canister, gasoline begins to lose its vapors, and it is they that ignite when the chainsaw is started. It is because of this that gardeners are faced with a number of typical problems, which include:

• Difficulty starting the motor;
• Rapid drop in ICE power;
• Accelerated wear of tool elements.

To prevent this, you need to regularly use only fresh fuel from proven gas stations. It is best to buy 2-3 liters of gasoline every morning before starting gardening. The use of fresh gasoline will make it easier to start the chainsaw, and significantly extend its life.

What to use chainsaw oil?

To find out exactly which oil to use to lubricate your chainsaw chain, you will need to consult the manufacturer’s instructions. Almost all tool manufacturers recommend pouring a product that stands out with the highest adhesion properties. This means that the material used to lubricate the chain must adhere to the metal surfaces of the chain and bar.

It is necessary to figure out what the adhesive properties are for. During the movement of the chain on the standard bar, the saw element reaches a high speed. If you use low-adhesion chain oil for a chainsaw for lubrication purposes, more than half of the liquid will fly off the top of the tire by inertia, never reaching its bottom. As a result, such oil will show itself to be ineffective, and the tire, along with the chain, will quickly fail due to constant friction.

Chainsaw oil: which to fill, in what ratio with gasoline, which for chains, and which for stars

Gasoline, as well as engine and chain saw oils play a key role in the stability of the tool. The durability of the main working mechanisms of the saw depends on their quality and properties, therefore, the choice of fuel and lubricants must be treated with special responsibility. Regular use of high-quality lubricants and fuel is the main guarantee of long-term operation of the chainsaw without unforeseen breakdowns.

Chainsaw Oil to Gasoline Ratio

Each chain saw company tweaks engines and base carburetors to operate with different amounts of lubricant. Therefore, the proportion of oil and gasoline for your chainsaw may differ slightly.

Most often, when mixing fuel with oil, manufacturers advise using proportions of 1:50, or 1:40. This means that 1 part of motor lubricant must be mixed in 50 or 40 parts of fuel, respectively.

It is quite easy to translate the proportion into a more accessible formulation. For example, 1 liter of fuel contains 1000 ml. If 1000 ml is divided by 40, you get 25 ml. This means that 25 ml of lubricant will need to be diluted for 1 liter of gasoline. The same formula should be used when the manufacturer recommends preparing the fuel mixture exclusively in a 1:50 ratio. To do this, 1000 ml must be divided by 50, resulting in 20 ml. This means that 20 ml of engine lubricant should be diluted in one liter of fuel.

Things are a little different with Chinese chainsaws. Their manufacturers advise to dilute gasoline for a chainsaw in a ratio of 1:25. This means that owners of Chinese tools need to stir exactly 40 ml of lubricant in 1 liter of pure gasoline. This ratio is due to the fact that in terms of assembly quality and selection of components, these chainsaws are slightly inferior to their Western counterparts. In engines of American, European and Japanese models, the distance between the cylinders and pistons is much less than that of chainsaws from China. In this regard, the amount of lubricant required to operate the former. Far less.

How to dilute gasoline with chainsaw oil?

A mixture of gasoline and oil must be constantly prepared in a clean container, on the walls of which there are measuring marks. This will give the owner of the chainsaw the ability to accurately determine the amount of gasoline and engine oil they mix. The material from which the container is made must be resistant to gasoline. Metal vessels work well for this.

Pour fuel and lubricant through a watering can to prevent loss of components. In order for the used lubricant to completely dissolve in the fuel, the filled container will need to be shaken several times. As a result, the gasoline mixture should become uniformly colored. In this case, you need to make sure that there is no precipitation at the bottom of the vessel.

Oil for two-stroke engines of chainsaws

Modern gasoline saws can be equipped with 2-stroke or 4-stroke engines. In the latter, oil is initially supplied to the parts of the crank-connecting rod group directly from the motor crankcase.

Unlike them, in two-stroke factory engines, the fuel enters the plane located under the piston. To refuel such chainsaws, engine oil must be added to fresh gasoline. It lubricates the rubbing engine parts, preventing their premature wear.

Oil for 2-stroke chainsaw engines must comply with a number of important parameters:

• When burning oil, a minimum amount of ash should be formed. It is best if the oil used is burned out in full;
• The lubricant must dissolve quickly in gasoline;
• Oil for 2-stroke engines must be free of harmful impurities that can lead to blockages in the carburetor lines.

The choice of oils for 2-stroke engines largely depends on the types of cooling systems. For the lubrication of internal combustion engines equipped with air cooling systems, 2T standard formulations are suitable. For engines cooled by liquid systems, choose oils marked TC-W3.

In any case, the oil for permanent lubrication of the engine of the tool used must be of the highest possible quality. During combustion, low-quality oils form a large amount of carbon deposits that settle on the cylinder walls and under the piston rings of the internal combustion engine. Because of this, the standard rings lose the ability to compress, as a result of which burrs appear on the inner walls of the engine cylinder. In addition, poor-quality lubrication leads to overheating of the parts of the crank mechanism. As a result, they jam and completely fail.

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 (like in a four-stroke engine), but directly to gasoline. At the same time, it is very important to observe the correct proportions of the ingredients, of course, in no case 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 post-Soviet countries the quality of gasoline is inferior to European, therefore, in our realities, it is better to use better quality gasoline.

As for the proportion of the petrol-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 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 follow the same steps to a ratio of 1:50, then we 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 that of Chinese chainsaws, therefore the required amount of oil differs almost twice.

Use a regular medical syringe with sufficient volume to measure the correct amount of oil.

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

Be sure to prepare the fuel mixture in a canister and pour ready-made special fuel into the gas tank! Never cook or mix 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. Under the conditions of domestic use, the entire volume of the prepared combustible 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 the saw has a dry carburetor) and now you can leave it until the next operation.

Unsuitable fuel mixture must be disposed of.
