For those who don't know, there are no valves in a two-stroke engine, and to lubricate the crankshaft and piston, oil is added to gasoline. These engines are on bikes. Often, bike owners wonder why the engine does not start well, works intermittently, why compression is lost, the piston is jammed. And often it's all about the oil, because gasoline is diluted with it. AT current time there is a lot of two-stroke oil on sale on store shelves, but this oil is not suitable for two-stroke engines that develop huge engine speeds.

Nai best oil for a bike
It creates a memory that when developing a two-stroke oil, it was invented, but not tested. And oils MC20, M8 should not be allowed even close to a two-stroke engine if you like to drive. But if you do not give a lot of gas when riding a bike, you can use these oils.

How to find what is grabbing a two-stroke engine
The 1st sign - in the engine suddenly there is a third-party noise, a sign of piston seizing, the engine loses momentum. At such a moment, it is necessary to throw off the gas and squeeze out the clutch, if you have time to do this, then the piston will come out of this situation without damage.

In what proportion to dilute the oil for the bike
The annotation suggests the following ratio: for a run-in motor - 1/25, for an unrun-in one - 1/20. No need to foolishly execute the proportions, everything will depend on how you press the gas. If you do not take this into account, then during a measured ride, diluted 1/20 gasoline will add candles, but if you drive a lot and if you dilute 1/25 gasoline, the engine will seize at the highest speed, which will lead to piston failure.

A two-stroke engine is designed in such a way that some of the oil can linger in the crankshaft and piston. When the gas is released to its fullest, the oil is very blown out from the piston, a mixture of 1/20 is needed here. How to dilute oil in gasoline to get 1/20? You need to take 10 liters. gasoline and half a liter of oil or 20 liters. gasoline and a liter of oil.

Why is the bike spitting oil out the muffler?
Everything is fine here, the bike is spitting out excess oil from the muffler. Do not worry if you pour a little oil into gasoline and the engine runs fine. When the engine fills the candles, and the engine works intermittently, then it is necessary to reduce the amount of oil in gasoline and add clean gasoline to the tank.

For two-stroke engines of bikes Tula, IZH Jupiter, IZH Planeta, Russian motor oil M8V is excellent. For such bikes as Planeta and IZH, the proportion for the consistency with a liter of gasoline is equal to - 25 grams per 1 liter of gasoline.

For the Tula bike, it is necessary to add a little more oil, 30 gr. is useful per liter of gasoline.

For a consistency with gasoline, any Russian affordable motor oil is suitable. The most important thing is that the engine oil should not be semi-synthetic and synthetic. Better than butter than M8V for a consistency with gasoline cannot be found, this engine oil is blue in color and very thick.

The main rule says that when mixing oil with gasoline, it is better to overfill than not to top up. If you do not add oil to gasoline, this will adversely affect the piston. Because of this, the engine will overheat very much and jamming will occur.

When poured into gasoline engine oil there is a small problem - the bike's acceleration dynamics drops. In other words, when the engine oil is overfilled, the bike will not rapidly gain momentum, and the engine will become very smokey. A lot of gray smoke will come out of the muffler. To prevent this from happening, it is necessary to observe the proportions of the oil when pouring it into gasoline.

The ratio of oil to gasoline is the main type of fuel for two-stroke engines. The fuel mixture guarantees the productive operation of the engine, helps to preserve its moving parts and reduce the number of breakdowns.

Fuel and oil for mixing

Correctly preparing the fuel mixture is not always easy. It is necessary to correctly calculate the proportions, mix liquids and properly store the finished mixture. Some drivers use their own recipes, adding their own "secret" ingredients, which may even include soda. To cooking fuel mixture was not a problem, you need to follow a few simple rules and follow the instructions from the manufacturer.

To prepare the mixture, standard gasoline and oil from various manufacturers are used. What grade of gasoline should be used to prepare the oil fuel mixture? Some mistakenly believe that 80-grade gasoline is best suited, because it has a lot of different additives. This is partly true, but that doesn't make it better than gasoline 92nd and 95th marks.

Moreover, it is very difficult to get gasoline of the 80th brand in Russia, because not one major fuel producer in the country now produces it. That's why the best option is gasoline of the 95th brand, which has almost the same cost as gasoline of the 92nd brand.

What oil is best for blending? It all depends on the preferences of the driver in a particular manufacturer. The only thing is that it is important to use the oil only for its intended purpose. If the oil is for a tractor or a boat, then it should not be used for a car.

Rules for the preparation of the fuel mixture

The process of preparing the fuel mixture should begin with a detailed acquaintance with the instructions attached to it. As mentioned at the beginning of the article, some drivers, who, in their opinion, have incredible experience, do everything “by eye”. Of course, over time, every driver knows how and what needs to be done, however, each mixture has its own differences, so it will never be superfluous to get acquainted with the advice from the manufacturer.

The main rules for the operation of the fuel mixture include:

• Never reduce the proportions of oil to gasoline. Oil is an expensive component, so many people decide to save on it. However, an insufficient amount of oil in the mixture leads to severe heating of the piston and engine cylinder. Because of this, scoring appears, which ultimately leads to the need for serious repairs.
• Do not use too much oil in relation to gasoline. An increase in oil proportions is also detrimental to engine performance. Too much oil leads to an increase in soot and rapid wear motor mechanism. Repair in this case will cost as much as in the first case.
• Do not store the prepared mixture for more than 30 days. Otherwise, it loses its properties and the use of such a mixture can harm the engine.
• Dirt, dust and other mechanical debris must not be allowed to enter, due to which the engine may become unusable.

Proportions and mixing process

How to determine the proportions for mixing oil with gasoline? Standard proportions should be indicated on the oil container. The amount of oil used may vary depending on the manufacturer, but 1:40 or 1:50 ratios are often used. A slight deviation from this ratio is allowed - this will not entail serious consequences.

Having determined the exact proportions, you need to proceed to the direct preparation of the mixture. In what way can this be done? For this, various containers are suitable. Important: in no case should you mix fuel with oil directly in the gas tank, pouring one liquid after another in turn - the mixture is always prepared separately and only then slowly poured into the gas tank.

For mixing, you can use a variety of devices, including:

1. Special containers for mixing. These are convenient canisters with two separate outlets - separately for gasoline and oil. To prepare the mixture in such a container, you just need to pour the right amount of liquid, close the container and tilt the canister several times. Such devices are very convenient, but they are quite expensive. If you have to mix the mixture often enough, then you should think about purchasing such a container.
2. Ordinary metal and plastic canisters. Standard canisters are the most practical fixtures. One has only to be careful when using plastic and glass canisters, because when using them, there is a possibility of a discharge of electricity. If you need to prepare a small amount of the mixture, you can use a regular plastic bottle.
3. Hand tools. To save money, many use improvised devices, such as baby horns and even syringes. Such funds are not very convenient, but they cost a penny.

How and where to store the finished mixture?

Manufacturers recommend storing the fuel mixture in a clean container, preferably a metal one. In no case should you leave the mixture in direct sunlight, because this will lead not only to the loss of its properties, but also to other very unpleasant consequences. The maximum shelf life of the finished mixture is 30 days.

Depending on how often the car is used, some drivers prepare the mixture once a week, others once a month. Of course, not every owner has the time to constantly measure the proportions and mix the fuel with the oil. It is important to remember that the "fresher" the mixture, the better it is for the engine.

Many use plastic cans and bottles as containers for storing the mixture. It is convenient and practical. There is always a place for a small plastic bottle. However, you should be careful about this. The fact is that during long-term storage in plastic containers, the fuel mixture can literally "eat" a hole in it. The process of corroding plastic is very fast. Therefore, it is best to use a metal container.

It may not be as convenient, but it is more reliable. If, nevertheless, there is a need to use a plastic canister, then remember that the mixture can be stored in it for no more than two to three days. Then it needs to be poured into another container.

Signs of misuse

The use of a contaminated or disproportionate mixture can lead to serious engine malfunctions. If you made a mistake when mixing, it's okay, because the car will tell you about it. You just need to be attentive to some signs, including:

• The appearance of dirt and various deposits on the carburetor.
• fast pollution fuel filter located in the gas tank.
• Oxidation of the carburetor walls and loss of elasticity of the rubber diaphragm in various parts of the gas tank. This symptom appears only during long-term storage of an unsuitable mixture directly in the car's gas tank.

The formation of resinous deposits in the carburetor area.

At the slightest manifestation of one of the signs, it is necessary to make changes to the mixing process, choosing more suitable proportions. In this way, you can choose the ideal fuel mixture and avoid serious engine malfunctions.

To prepare the correct fuel mixture yourself, which will ensure perfect engine performance, you must use the right fuel, strictly adhere to the proportions specified by the manufacturer, use a suitable container and store the finished mixture for no longer than 30 days. By adhering to these rules, you will prepare the perfect mixture for your car engine.

Video: preparing a fuel mixture for a two-stroke engine

For those who don't know, there are no valves in a two-stroke engine, and to lubricate the crankshaft and piston, oil is added to gasoline. These engines are on motorcycles. Often, motorcycle owners wonder why the engine does not start well, works intermittently, why compression disappears, the piston is jammed. And often it's all about the oil, because gasoline is diluted with it. There are a lot of two-stroke oils on the market today, but this oil is not suitable for two-strokes that develop high speed engine.

The best motorcycle oil

It seems that when developing a two-stroke oil, it was invented, but not tested. And MC20, M8 oils should not be allowed to come close to a two-stroke engine if you like to drive. But if you do not give a lot of gas when riding a motorcycle, you can use these oils.

How to determine what is sticking in a two-stroke engine
The first sign - suddenly appears in the engine extraneous noise, a sign of piston sticking, the engine loses speed. At such a moment, you need to release the gas and squeeze the clutch, if you have time to do this in time, then the piston will come out of this situation without damage.

How much to dilute motorcycle oil
The instructions suggest the following ratio: for a run-in engine - 1/25, for an unrun-in one - 1/20. No need to stupidly follow the proportions, everything will depend on how you press the gas. If this is not taken into account, then quiet ride diluted 1/20 gasoline will add spark plugs, but if you drive hard and if you dilute 1/25 gasoline, the engine will seize at maximum speed, which will lead to piston failure.

A two-stroke engine is designed in such a way that some of the oil can linger in the crankshaft and piston. When the gas is released to its fullest, the oil is strongly blown out from the piston, a mixture of 1/20 is needed here. How to dilute oil in gasoline to get 1/20? You need to take 10 liters of gasoline and half a liter of oil or 20 liters of gasoline and a liter of oil.

Why does a motorcycle spit out oil through the muffler?
Everything is fine here, the motorcycle spits out excess oil from the muffler. Do not worry if you lightly pour oil into gasoline and the engine runs fine. When the engine fills the candles, and the engine runs intermittently, then you need to reduce the amount of oil in gasoline and add clean gasoline to the tank.

For two-stroke motorcycle engines Tula, IZH Jupiter, IZH Planeta is well suited for motor domestic oil M8B. For motorcycles such as Planet and IZH, the proportion for a mixture with a liter of gasoline is 25 grams per 1 liter of gasoline.

For Tula's motorcycle, you need to add a little more oil, 30 grams per liter of gasoline.

For a mixture with gasoline, any domestic cheap motor oil is suitable. The most important thing is that the engine oil should not be semi-synthetic and synthetic. There is no better oil than M8B for a mixture with gasoline, this engine oil has a dark blue color and is very thick.

The main rule says that when mixing oil with gasoline, it is better to overfill than not top up. If you do not add oil to gasoline, then this will adversely affect the piston. Because of this, the engine will overheat and jam.

When pouring engine oil into gasoline, there is a small problem - the acceleration dynamics of the motorcycle drops. In other words, when the engine oil is overfilled, the motorcycle will not quickly gain momentum, and the engine will begin to smoke a lot. A lot of gray smoke will come out of the muffler. To prevent this from happening, you need to observe the proportions of oil when you pour it into gasoline.

For those who do not know, I will explain what a two-stroke engine is, I will not go into much detail, in short, there are no valves in a two-stroke engine, oil is added to gasoline to lubricate the piston and crankshaft.

Such engines are on motorcycles (although four-stroke ones have been installed more recently), chainsaws with two-stroke engine, gas mowers, some voltage generators, etc. The owners of motorcycles, chainsaws, lawn mowers often wonder why the piston is stuck, or why the compression quickly disappears, that the engine does not start well, starts to work intermittently, remove the cylinder, the piston with large scuffs and frantic output.

I also once asked this question, it turned out that the whole thing was in the oil with which gasoline is diluted.

There is a lot of special two-stroke oil on sale, I don’t even go to it now, this oil is not suitable for two-stroke engines developing high engine speeds.

Of course, if you have an IZH-Planet, this is a low-speed motorcycle, then you can pour two-stroke oil into gasoline, or be very gentle on your motorcycle, don’t give it gas all the way, then two-stroke oil will go, but if you like to step on the gas, this oil will quickly ruin piston group two-stroke.

It seems that the developers of two-stroke oil simply came up with it but did not even test it, and oils such as M8, MC20 should not be allowed close to a two-stroke engine if you like to drive, and if you don’t give a lot of gas, then these oils can be used.

But they will still wear out the piston group of a motorcycle, chainsaws, gas mowers very quickly, in short, kill a two-stroke.

How do I find a good motorcycle oil?

During my life I have ridden on different motorcycles, while I was driving Minsk, Voskhod, IZH-Planet, I didn’t even think about oil, the engines worked fine. But how I bought IZH-PS so after the first good race I had a piston jammed, I thought, so there were only problems with IZH-PS until I give gas to failure, but it’s worth giving gas as a piston or crankshaft wedged. Disappointed in IZH-PS.

In my youth I was engaged in motocross for two years, we had cross-country ChZs, I remember there weren’t much problems with the piston, although they gave them in the ass oh so good, I also remember that the smell of smoke from the exhaust was very different from the usual smoke of a motorcycle. But the fool was not interested in the coach what kind of oil he poured into gasoline, but I know for sure that in addition to oil he added castor oil, but since I don’t know exactly the composition of gasoline and oil for motocross bike, I will not lie and invent anything.

I bought a cross-country ChZ-250, for the first time I poured two-stroke oil into gasoline, but as soon as I succumbed to it, I felt that the engine was starting to tighten (may jam), I had to throw off the gas and switch to moderate engine speeds.

The case helped, I decided to go fishing on a cross-country ChZ-250, you can drive it off-road shortening the path, but the two-stroke oil ran out, the question arose of how to dilute gasoline with oil. There was only semi-synthetic LUKOIL four-stroke oil, I decided to dilute gasoline with this oil, I think I won’t drive slowly, I’ll drive and I won’t harm the engine. But what a surprise I had when the motorcycle engine started running much softer, pulled faster, although gasoline was diluted with semi-synthetic four-stroke oil, gas was applied, beauty, the engine flogs and there are no signs of piston seizing.

While I got to the pond, I squeezed the maximum out of this cross-country ChZ-250, I got great pleasure from riding, since then I have been diluting gasoline into a motorcycle and a chainsaw with only four-stroke semi-synthetic oil, very pleased.

It turns out that semi-synthetic four-stroke oil is the best oil for a two-stroke engine and is cheaper than a special two-stroke oil.

If you don't believe me, check for yourself which is the best oil.

How can you tell if a two stroke engine is sticking?

The very first sign, extraneous noise suddenly appears in the engine, the engine starts to lose speed, this is a sign of piston seizure. At this point, immediately release the gas if the motorcycle and squeeze the clutch, if it is in time, the piston will come out of this situation without damage.

How to dilute the oil in what proportion for a motorcycle, chainsaw, gas mower, gas generator, etc.?

The instructions give such ratios, for an unrun-in engine 1/20 for a run-in 1/25. But here you can’t stupidly fulfill these proportions, it all depends on how you press the gas.

If you don’t drive hard, drive calmly on a motorcycle or don’t squeeze full throttle with a chainsaw, then pour gasoline diluted with 1/25 oil into a run-in two-stroke engine for the engine will be fine. But if you like to open the gas at full speed, giving the engine maximum speed, then dilute gasoline with oil in the same proportion as for running in 1/20, since the engine will need increased lubrication when operating at maximum speed.

If this is not taken into account, then diluted 1/20 gasoline during a quiet ride will often add candles, but if you drive and love full throttle, diluting 1/25 gasoline will seize the engine at maximum speed, and this can lead to piston failure.

A two-stroke engine is designed so that part of the oil lingers in the piston and crankshaft, but when you give out gas to the fullest, it is blown out very strongly from the piston without lingering here, laughing 1/20 is definitely needed.

An example of how to dilute oil in gasoline, take 1/20, it turns out that for 20 liters of gasoline 1 liter of oil, 10 liters of gasoline 0.5 liters of oil.

Why does a saw or motorcycle spit out oil through the muffler?

Everything is fine here, the saw is like that and a motorcycle with a two-stroke engine spits out excess oil from the muffler. So you slightly pour the oil into gasoline, if the engine works fine, you should not worry. And if the engine floods the candles, the engine starts to work intermittently, then reduce the amount of oil in gasoline by adding clean gasoline to the tank.

Gorobinsky S.V.

The main type of fuel for two-stroke engines is a mixture of oil and gasoline. One of the reasons for damage to the mechanism may be the incorrect manufacture of the presented mixture. The situation is also fraught with trouble when there is no oil in gasoline at all. For the manufacture of a mixture of this kind, a special oil is used, which has a special marking. It indicates what exactly you need to use it for. Experienced drivers and mechanics know that creating an effective mixture is not easy. It is necessary to correctly calculate the ratio of gasoline and oil for a two-stroke engine.

Some car owners resort to personal recipes, supplementing the mixture with certain "secret" ingredients, among which there is soda. For the correct preparation of the fuel mixture, certain requirements and recommendations of the manufacturer must be observed.

Fuel and oil

To determine exactly what ratio of gasoline to oil to use for a two-stroke engine, it is important to know everything operational properties equipment that requires fuel. For this purpose, the most common gasoline and oil from various manufacturers are most often used. For the described process, 92nd or 95th gasoline is best suited.

It should be noted that many manufacturers write a variety of proportional ratios of a mixture of gasoline and oil for two-stroke engines. It is important to always look at the oil canister and the instructions for its use, where the necessary proportions can be written. The brand of oil must be chosen, focusing on the preferences of the car owner. It is very important to study the product description before buying, which must indicate what equipment it is intended for.

Rules for making a mixture

The entire process for the production of the presented mixture must begin with a clear study of the instructions. As mentioned earlier, some drivers with great experience, everything is done by eye. Naturally, over time, each driver remembers the proportions. However, it is better to read the instructions before starting the manufacturing process.

Rules for using the mixture

The proportions of gasoline and oil for two-stroke engines should never be changed. Some drivers do not attach much importance to this rule. Since oil is expensive, they try to save it. However, an insufficient amount of this component in the mixture is fraught with overheating of the piston and cylinder of the engine itself. As a result, problems arise that require a thorough repair.

How much oil should be added to gasoline for a two-stroke engine if its percentage cannot be reduced? If you increase the amount of this component, it will affect the functioning of the engine. Excess oil will give carbon deposits, and the motor mechanism will wear out faster.

It is important to remember that the mixture cannot be kept for more than a month, as it loses its own characteristics, and its use will adversely affect the engine.

Care must be taken to ensure that no dirt, dust or other debris gets into the presented mixture, due to which the engine will stop working.

Mixing process and proportions

How to understand how much oil per liter of gasoline for a two-stroke engine is required? It is very easy to calculate since all the basic data is at hand. For example, directly on the packaging it is written how much oil per liter of gasoline is needed to make a high-quality mixture. The amount of this ingredient may vary depending on the manufacturer. The most commonly used proportions are 1:50 or 1:40. There may be some deviations from these parameters.

As soon as clear proportions are determined, it is necessary to start making the mixture. For this process, the most various capacities. It is very important to know that it is forbidden to mix fuel with oil in the gas tank itself. The mixture must be done separately. You can pour it into the tank only after the end of the process.

A container in which you can prepare and store the mixture

1. Special containers for mixing. They look like canisters with several holes. To make a mixture, the already calculated ratio of gasoline and oil for two-stroke engines should be poured into a canister, closed and tilted a couple of times. Such containers are very comfortable, but their cost is high. If you need to make mixtures often, it is better not to spare money and buy yourself a similar container.
2. Canisters made of plastic or metal. It is necessary to be careful when using such containers made of glass or plastic, as their use may cause a discharge of electricity. If you need to make a little mixture, then a simple plastic bottle is perfect.
3. Hand tools. To save money, a large number of motorists use a wide variety of containers at their disposal. This is not prohibited, but you need to be sure that gasoline will not corrode the container material.

Mix storage

Manufacturers say that it is best to keep the mixture not just in a clean container, but in one that is made of metal. It is important to remember that such containers should not be left under the scorching sun. Heating will not only spoil the mixture, but can provoke more unpleasant consequences.

The maximum storage time of the fuel mixture is a month.

Depending on how often the car is used, some drivers make the mixture several times a month, while others - several times a week. Naturally, not every motorist constantly measures the ratio of gasoline and oil for two-stroke engines, but prepares the mixture for the future. However, do not forget that a fresher product will have a better effect on the functioning of the engine.

A lot of motorists use plastic canisters, as well as plastic bottles, to store the mixture. It is quite comfortable and practical. For a bottle, you can easily find a suitable place in the garage. But with such a container, you need to be careful. since during long-term storage in a plastic container, the mixture can violate its integrity. It is worth noting that the process of corroding plastic is quite fast. For this reason, it is more reliable to store mixtures in metal containers.
