For those who don’t know, I’ll explain what a two-stroke engine is, I won’t go into too 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 found on motorcycles (although recently four-stroke ones are used more often), chainsaws with a two-stroke engine, gas mowers, some voltage generators, etc. Owners of motorcycles, chainsaws, and gas mowers often wonder why the piston is jammed, or why the compression quickly disappears, that the engine does not start well, starts working intermittently, they remove the cylinder, the piston with large scuffs and crazy output.
I also once asked myself this question, it turned out that the whole issue is the oil with which gasoline is diluted.
There are a lot of special two-stroke oils on sale, I don’t even go near them now, this oil is not suitable for two-stroke engines developing high engine speeds.
Of course, if you have an IZH-Planet, it is a low-revving motorcycle, then you can pour two-stroke oil into gasoline, or be very gentle with your motorcycle, do not give it gas all the way, then two-stroke oil will work, but if you like to give it gas, this oil will quickly ruin the piston two-stroke group.
It seems that the developers of two-stroke oil simply invented 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 do not give a lot of gas, then these oils can be used.
But they will still very quickly wear out the piston group of a motorcycle, chainsaws, gas mowers, in short, kill a two-stroke.
How I found a good motorcycle oil
During my life I have ridden different motorcycles, while I rode Minsk, Voskhod, IZH-Planet, I didn’t even think about oil, the engines worked fine. But when I bought the IZH-PS, after the first good race my piston jammed, I thought about it, there were only problems with the IZH-PS, as long as I don’t give the gas it goes all the way, but as soon as I give it the gas the piston or crankshaft jams. Disappointed in IZH-PS.
In my youth, I was involved in motocross for two years, we had cross-country ChZs, I remember there were no major problems with the piston ones, although they kicked 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 didn’t ask the coach what kind of oil he poured into the 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 a motocross motorcycle, I won’t lie and invent anything.
I bought a cross-country ChZ-250, at first I poured two-stroke oil into the gasoline, but as soon as I gave it in, I felt that the engine was starting to drag (it might jam), I had to let off the gas and switch to moderate engine speeds.
Chance helped, I decided to go fishing on the cross-country ChZ-250, you can drive it off-road, shortening the distance, but I ran out of two-stroke oil, the question arose of what oil to dilute the gasoline with. There was only four-stroke semi-synthetic LUKOIL oil, I decided to dilute the gasoline with this oil, I think I won’t drive it, I’ll get there slowly and won’t harm the engine. But what a surprise I was when the motorcycle engine started running much softer, pulled faster, although I diluted the gasoline with four-stroke semi-synthetic oil, applied gas, beautifully, the engine was flogging and there were no signs of the piston sticking.
By the time I got to the pond, I was squeezing this cross-country ChZ-250 to the maximum, I got great pleasure from the ride, since then I have been diluting gasoline in my motorcycle and chainsaw only with four-stroke semi-synthetic oil, very pleased.
It turns out that four-stroke semi-synthetic oil is the best oil for a two-stroke engine and is cheaper than special two-stroke oil.
If you don’t believe me, check for yourself which is the best oil.
Changing the oil in the Izh Planet-5 gearbox
Changing the Izh Planet-5 gearbox oil is mandatory periodic maintenance. This means that a similar procedure will have to be carried out more than once during operation. If the Izh Planet-5 is new, then replacement will need to be done after the first 500 km, then this must be done every 10,000 km. It is better to carry out all activities immediately after using the motorcycle, while the oil is still warm. Replacement algorithm:
- For convenience, the motorcycle can be mounted on a central stand.
- It is necessary to place a container with a volume equal to 1.5-2 liters under the engine crankcase. This is where the already used oil will be drained.
- At the bottom of the crankcase there is a button that can be freely unscrewed with a 22 mm wrench. This is exactly what needs to be done and then drain the oil.
- The drain button is screwed back in.
- Now work is done with the hatch-emblem located on the left crankcase cover. The rear fastening screw is loosened, and the front screw is completely unscrewed.
- The retaining hatch on the rear screw is turned. After this, a “window” in the crankcase cover will open. Engine oil is poured in there. Then, in the same sequence, everything is put in place and tightened.
A video on changing the oil can be viewed at the link:
Why does a saw or motorcycle spit oil through the muffler?
Everything is fine here, I saw it like that and a motorcycle with a two-stroke engine spits out excess oil from the muffler. This means that you lightly pour oil into gasoline; if the engine is running perfectly, there is no need to worry. And if the engine floods the spark plugs, the engine starts to work intermittently, then reduce the amount of oil in gasoline by adding clean gasoline to the tank.
Gorobinsky S.V.
Household and professional chainsaws are powered by two-stroke internal combustion engines running on a dosed mixture of gasoline and motor oil adapted to difficult operating conditions. The correct proportions of oil and gasoline for a chainsaw are one of the important conditions for stable traction characteristics of the engine and low-cost development of its designated resource.
The need to obtain sufficiently high power from a small-cc power unit forces chainsaw engines to be operated at high-speed modes, so increased demands are placed on the quality of both components of the fuel mixture.
The main component of the fuel mixture for chainsaw engines is gasoline with an octane number of at least 92. Expired consumables made from gas condensate containing water and mechanical impurities are not suitable for preparing fuel.
- The opinions of experts on the use of gasoline of different brands are ambiguous. On the one hand, it is recognized that domestic A-92 gasoline does not fully comply with European standards.
- On the other hand, the quality of A-95 gasoline is questioned due to the high content of anti-knock additives. You can use this fuel to prepare fuel for a chainsaw only if you are completely 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 rating.
Irreversible changes in the operating properties of fuel also occur when stored in plastic containers for a sufficiently long time, regardless of the level of its gasoline and oil resistance.
Planet-5 gearbox repair
The gearbox is repaired after disassembling the gearbox. At this stage, the cause of the malfunction is identified and the necessary parts are replaced. At the same time, it is best to buy parts as a set, so there will be no discrepancies in size during assembly of the unit. If you follow the instructions given above, you can easily repair the gearbox yourself. For convenience, parts can be signed during disassembly. They should be laid out on a clean surface to prevent foreign bodies from getting into the structure in the future.
The result depends on the quality of the work performed. Therefore, it is important to carefully monitor the implementation of all points for assembling the gearbox with new parts, with the help of which the old ones were replaced.
Lubricants
More stringent criteria for selecting an oil component. The best option is a mineral or semi-synthetic motor oil recommended by the manufacturer, designed for use in high-speed two-stroke air-cooled internal combustion engines.
The advantage of mineral oils is their lower cost. Their more expensive semi-synthetic and synthetic analogues compare favorably with improved performance characteristics and compliance with environmental standards.
Synthetics:
- maintain performance properties over a wide range of operating temperatures;
- do not form soot;
- contain detergents, antioxidants, preservatives and other additives useful for the operation of the power unit.
Benefits of branded oils
Many domestic and foreign manufacturers specialize in the production of special motor oils, but the highest rating indicators are for branded products Shtil, Husqvarna and Makita.
Only in certain parameters the branded assortment is inferior to domestic motor oils of the Lukoil brand.
Taking into account external factors, the fuel mixture can be adjusted to increase the amount of oil. This need arises at the stage of a new tool, as well as at high air temperatures. In this case, the standard dosage of oil is increased by 20%.
In practice, an increase in the percentage of oil in the fuel mixture is used if its characteristics do not fully meet the stated requirements. How much oil per liter of gasoline is needed in each specific case is determined by the sawyer himself.
Measuring containers
To maintain the correct proportion of gasoline and oil, a calculation table applied to the saw body can be used. Branded containers of leading motor oil manufacturers are equipped with built-in measuring devices that provide accurate dosage of oil for different volumes of the fuel mixture.
Measuring utensils are included in the factory kit of many budget chainsaw models. In some cases, a medical syringe with a volume of 20 cm3 will help to dilute gasoline with oil in a given proportion.
Features of preparation and storage of the fuel mixture
Safety regulations require diluting gasoline and oil in a metal canister. This eliminates the risk of static electricity and fuel combustion.
Experts advise pouring oil into an incomplete container, stirring thoroughly, and then topping up with pure gasoline to the specified level. Saving working time by preparing the working mixture directly in the gas tank of the chainsaw should be excluded from everyday practice.
This technology is fraught with fuel system failures due to large amounts of oil getting into the carburetor, requiring disassembly and thorough washing.
It is better to prepare the mixture in quantities that should be enough to complete one-time work. The problem is the irreversible deterioration of the working properties of the mixture during storage. It is recommended to use the finished composition over the next few days.
A mixture of gasoline and month-old oil impairs the traction capabilities of the engine. There is also the formation of resinous compounds in the fuel system and intense carbon formation in the combustion chamber, loss of mobility of the piston rings.
- With minimal damage to quality, it is advisable to store gasoline and oil for no more than 2 weeks. At an ambient temperature of 25 degrees Celsius or more, this period is reduced to 8-10 days.
- In order to save money, the expired mixture can be gradually consumed by mixing it into the fresh composition in an amount of no more than 10% of the total volume.
To avoid problems associated with fuel system failure, it is recommended to filter the prepared mixture through a non-fibre material such as suede, or a fine-mesh twill weave or metal mesh.
Features of running in a new tool
This concept includes a gentle operating mode of the chainsaw at the initial stage of its operation. The technology also provides for the engine to operate on a mixture with an increased content of motor oil by 20%.
The break-in time in engine hours is indicated in the attached instructions. In practice, to reach the working level of the tool, 3-5 refills of the saw’s gas tank are sufficient.
New models do not need to be broken in, but it is not recommended to use the chainsaw with heavy loads during the first hours of operation.
For those who don't know, a two-stroke engine has no valves and requires oil to be added to gasoline to lubricate the crankshaft and piston. These engines are found on motorcycles. Motorcycle owners often wonder why the engine does not start well, runs intermittently, why compression disappears, or why the piston is jammed. And often it’s all about the oil, because they dilute gasoline with it. Currently, 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 high engine speeds.
Best motorcycle oil
It seems that when developing two-stroke oil, it was invented, but not tested. But MC20 and M8 oils should not be allowed anywhere near a two-stroke engine if you like to race. But if you don’t give a lot of gas when riding a motorcycle, you can use these oils. How to determine what is seizing in a two-stroke engine
The first sign is that extraneous noise suddenly appears in the engine, a sign of the piston sticking, and the engine loses speed. At such a moment, you need to release the gas and squeeze the clutch; if you manage to do this in time, then the piston will come out of this situation without damage.
In what proportion should you dilute motorcycle oil?
The instructions suggest the following ratio: for a run-in engine - 1/25, for an unrun-in engine - 1/20. There is no need to stupidly follow the proportions; everything will depend on how you step on the gas. If you do not take this into account, then when driving quietly, diluted gasoline 1/20 will top up the spark plugs, but if you drive hard and if you dilute gasoline 1/25, the engine will begin to seize at maximum speed, which will lead to piston breakage.
A two-stroke engine is designed in such a way that some of the oil can be retained in the crankshaft and piston. When the gas is released to its fullest, the oil is strongly blown out of 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 oil out of the muffler?
Everything is fine here, the motorcycle spits out excess oil from the muffler. Don't worry if you add a little oil to the gasoline and the engine runs great. When the spark plugs are flooded 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 engines of motorcycles Tula, IZH Jupiter, IZH Planet, domestic motor oil M8V is well suited. For motorcycles such as Planet and IZH, the proportion for the mixture with a liter of gasoline is 25 grams per 1 liter of gasoline.
For a Tula motorcycle you need to add a little more oil, 30 grams per liter of gasoline.
Any domestic cheap motor oil is suitable for a mixture with gasoline. The most important thing is that the motor oil is not semi-synthetic or synthetic. You cannot find a better oil than M8B for a mixture with gasoline; this engine oil is dark blue in color and very thick.
The main rule is that when mixing oil with gasoline, it is better to overfill than underfill. If you do not add oil to gasoline, this will have a detrimental effect on the piston. Because of this, the engine will overheat and jam.
When you pour motor oil into gasoline, there is a small problem - the motorcycle's acceleration dynamics drop. In other words, if the engine oil is overfilled, the motorcycle will not gain speed quickly, and the engine will begin to smoke heavily. A lot of blue smoke will come out of the muffler. To prevent this from happening, you need to maintain the proportions of oil when pouring it into gasoline.
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 incorrect production of the presented mixture. The situation when there is no oil in gasoline at all is also fraught with troubles. To make a mixture of this kind, a special oil is used, which has a special marking. It indicates what exactly it should be used 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, including soda. For the correct production of the fuel mixture, it is necessary to comply with certain requirements and recommendations of the manufacturer.
What kind of oil and what kind of gasoline to pour into an IZh motorcycle
Can't decide which IZH motorcycle is better - Dnepr or Ural? On various thematic forums you can find many reviews about motorcycles. Some are inclined to believe that the best motorcycle is the Dnepr 11, others consider the Izh Planet 5, and some say the Ural. Russian motorcycles have always been in great demand due to their availability and low operating costs. Such motorcycles require very careful and attentive maintenance.
Do you want to know what the weight of an Izh Planet or Jupiter motorcycle is without a sidecar? And everywhere there is information only about weight with a stroller? The weight of such a motorcycle will be more than 150-160 kg without taking into account fuel and oil, which will still add up to 15-20 kg. It all depends on the chosen model and year of manufacture. We recommend registering for thematic forums, where there are a huge number of interesting topics for discussion. You can learn a lot of useful tips about the repair and operation of Soviet motorcycles, their strengths and weaknesses.
Many motorcycle owners ask the same question - what kind of oil and what kind of gasoline to fill their motorcycle with? M8B engine oil, which has excellent characteristics, is ideal for domestic motorcycles. The recommended proportion for a mixture of oil and gasoline is approximately 1:50. If we consider this in practice, then it turns out that for every liter of AI-92 gasoline, about 25 grams of motor oil are added. For some models, such as the Urals, this proportion should be increased to 30 grams per liter of fuel. It is recommended to dilute some motor oils from gasoline in a ratio of approximately 1:25.
All necessary spare parts for the IZH motorcycle can be found in specialized stores (for example https://motaki.ru/index.php?route=product/category&path=125_80) or on the market. They are affordable and not that hard to find. If you need high-quality oil, find out about it on the market, about specialists who have been selling spare parts and fuels and lubricants for many years. And remember that the IZH clutch operates in an oil bath. MC-20 is ideal, but as for automobile motor oil, it is better not to fill it in, as problems will arise with adjusting the clutch.
For motorcycles Dnepr, Ural, Planet, Jupiter and so on, you can use any domestically produced motor oil, even the cheapest. For mixtures with gasoline, it is not recommended to use synthetic or semi-synthetic oil. It is better to give preference to the so-called “mineral water”. Find out from the manager which oil to fill in the shock absorbers of an IZH motorcycle (if the shock absorber itself flies, look for it at https://motaki.ru/index.php?route=product/product&path=125_80&product_id=6918), and which one to add to the gearbox to they lasted longer. Choose only high-quality motor oil!
Fuel and oil
To accurately determine what ratio of gasoline to oil to use for a two-stroke engine, it is important to know all the operational properties of the equipment for which fuel is needed. For this purpose, the most common gasoline and oil from various manufacturers are most often used. For the described process, 92 or 95 gasoline is best suited.
It should be noted that many manufacturers write very different proportional ratios of the 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 required proportions may be written. The brand of oil must be chosen based on the preferences of the car owner. Before purchasing, it is very important to study the description of the product, which must indicate what equipment it is intended for.
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 can lead to overheating of the piston and cylinder of the engine itself. As a result, problems arise that require major repairs.
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 cause carbon deposits, and the motor mechanism will wear out faster.
It is important to remember that you cannot keep the prepared mixture for more than a month, as it loses its own characteristics, and its use will have a detrimental effect on the engine.
It is necessary to ensure that no dirt, dust or other debris gets into the presented mixture, due to which the engine will stop working.
Izh Jupiter 5 where does the engine oil go? | Topic author: Veronica
Nina Stout correctly wrote that to lubricate the engine, oil is mixed with gasoline in a ratio of 1:20. Separately, oil is poured into the gearbox Vadim. I’ll just clarify a little: in Izh Jupiter 5, oil is poured not from the right side but from the left, not from above but from the side Ilya, and there is no control screw there, there is a dipstick on the mentioned cap. More oil is poured into the flywheel cavity. For filling into the flywheel cavity, there is a screw plug with a slot for a screwdriver on the left half of the engine, near the engine mounting point. You need to put the motorcycle on a flat surface, unscrew this plug and pour Leonid oil into the hole so that the oil is flush with the edge of the Oksana hole.
Mixing process and proportions
How do you know how much oil per liter of gasoline is required for a two-stroke engine? It is very easy to calculate since all the basic data is at hand. For example, it is written directly on the packaging how much oil per liter of gasoline is needed to produce 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 such parameters.
As soon as clear proportions are determined, we must begin making the mixture. A variety of containers are perfect for this process. It is very important to know that it is prohibited to mix fuel with oil in the gas tank itself. The mixture must be made separately. You can pour it into the tank only after the process is completed.
What kind of oil is poured into the Izh Jupiter 5 engine
Excerpts from the operating manual for IZH Planet 5-01.

Container in which you can prepare and store the mixture
- Special containers for mixing. They look like canisters with several holes. To make the 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 they are also expensive. If you need to make mixtures often, it is better not to waste money and buy yourself a similar container.
- 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 result in an electrical discharge. If you need to make a small amount of mixture, a simple plastic bottle will do just fine.
- Tools at hand. To save money, a large number of car enthusiasts use a variety of containers at their disposal. This is not prohibited, but you need to be sure that gasoline will not corrode the container material.
