2-Stroke Oil

Two-stroke oil is used for motorcycles to lubricate the bearings that are at the end of the crankshaft, the connecting rod bearings, and the cylinder walls.

This mixture of fuel, oil, and air helps to coat everything with the two-stroke engine oil. It is sometimes referred to as 2T or two-cycle oil as well.

It is essential for this oil to be mixed with gasoline, in order to be distributed efficiently in the system.

The fuel may sometimes burn along with the duel, which can lead to exhaust emissions along with smoke or a unique odor.

4-Stroke Oil

The 4-stroke oil is used in 4 stroke engines, where the oil and gasoline are not mixed.

A car’s engine is a 4-stroke engine, for example. But there are plenty of dirt bikes that have a 4-stroke engine.

Difference Between 2-Stroke and 4-Stroke Oils

When you are choosing which oil you should buy, you must first understand the fundamental difference between the 2-stroke and 4-stroke oils.

The primary difference, which most people do not know, is not in the weight. In fact, no matter which oil you buy, it will either be premix or injector safe.

Most of the motocross bikes run smoothly on premix oils. This means you do have the option of mixing your oils with a bit of gas before you put it in the gas tank.

Similarly, you can adopt different mixing ratios. You should, however, consider your bike’s manual to find out what would be the best mix for optimum performance.

When you are measuring the oil, always use a jug so that your ratio of gas to oil is accurate.

However, if the engine on your bike works on auto lube, you may want to find out the right type of oil for that.

You should, however, keep in mind that every premix 2-stroke oil will not work well with an auto lube system.
