How I Found Good Motorcycle Oil

During my life I have traveled on different motorcycles, while driving in Minsk, Voskhod, IZH-Planeta did not even think about oil, the engines worked normally. But as I bought IZH-PS, after the first good arrival, my piston jammed, I thought, so there were only problems with IZH-PS, until I give gas until it fails, but it costs to give gas as the piston or crankshaft wedged. Disappointed with IZH-PS.

In my youth, I was engaged in motocross for two years, we had cross-country CHZ, I remember there were no problems with the piston, although they gave them in the ass, oh, how good, I also remember that the smell of smoke from the exhaust was very different from ordinary motorcycle smoke. 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 for sure the composition of gasoline and oil for a cross-country motorcycle, I will not talk and invent anything.

I got a cross-country CHZ-250, for the first time I poured two-stroke oil into gasoline, but as soon as it gave in, I felt that the engine was starting to tighten (it could jam), I had to throw gas and switch to moderate engine speed.

The case helped, I decided to go on a cross-country CHZ-250 for fishing, on it you can go off-road by shortening the path, but the two-stroke oil ran out, the question arose with what oil to dilute gasoline. There was only LUKOIL semi-synthetic four-stroke oil, I decided to dilute the gasoline with this oil, I think I will not drive it slowly and I will not do any harm to the engine. But what a surprise I had when the motorcycle engine started to work much softer, pulled faster, although the gasoline was diluted with four-stroke oil with semi-synthetics, it turned on gas, beauty, the engine smacks and there are no signs of the piston sticking.

While I reached the pond, I squeezed the maximum out of this ChZ-250 motocross, I got great pleasure from driving, since then I dilute gasoline in a motorcycle and a chainsaw with only four-stroke semi-synthetics oil, very pleased.

It turns out that a four-stroke semi-synthetic 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 to tell if a two-stroke engine is picking up?

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

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

The instructions give such ratios for a non-run-in engine 1/20 for a run-in 1/25. But here you cannot stupidly fulfill these proportions, it all depends on how you step on the gas.

If you do not drive too much, ride quietly on a motorcycle or do not squeeze full throttle with a chainsaw, then pour gasoline diluted with 1/25 oil for the engine into a run-in two-stroke engine. But if you like to open the gas at full speed, giving the engine maximum speed, then dilute gasoline with oil in the proportion as for running in 1/20, since the engine working at maximum speed will need increased lubrication.

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

The two-stroke engine is designed so that part of the oil is retained in the piston and crankshaft, but when you give out gas to the full coil, a little is blown out very strongly from the piston without lingering here, laughing 1/20 is necessary.

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

The best oil for a two-stroke engine

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 found on motorcycles (although recently they have been using four-stroke engines more), chainsaws with a two-stroke engine, lawn mowers, some voltage generators, etc. The owners of motorcycles, chainsaws, lawn mowers, often wonder why the piston is jammed, or why the compression quickly disappears, that the engine starts poorly, starts to work intermittently, remove the cylinder, the piston with large seizures and frantic output.

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

There are 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-rimming motorcycle, then you can pour two-stroke oil into gasoline, or spare your motorcycle very much, do not give it gas all the way, then two-stroke oil will go, but if you like to gas, this oil will quickly spoil the piston a 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 the 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, lawn mowers, in short, kill a two-stroke.
