Two stroke and four-stroke engines are different types of internal combustion engines. The main difference between them is how the fuel and air mixture is introduced into the cylinder. In a two-stroke engine, the fuel and air are mixed together in a carburetor and then introduced into the cylinder through a single port. In a four-stroke engine, the fuel and air are mixed together in a carburetor and then introduced into the cylinder through two separate ports.
The composition of the fuel is different for 2 stroke and 4 stroke engines. Two stroke fuel contains oil in addition to the gasoline. The ratio of oil to gasoline is typically between 1:20 and 1:50. This oil is needed to lubricate the piston and cylinder walls of the engine. The fuel used in four stroke engines does not have any oil in it, because it is not needed for lubrication.
Using two stroke fuel in a four stroke engine can cause serious damage to the engine. The oil in the fuel can cause the spark plugs to foul and the piston rings to stick. This can lead to a loss of power and, eventually, engine failure.
If you accidentally put two stroke fuel in a four stroke motorcycle, you should stop riding it immediately and have the fuel tank drained. You should also have the engine checked by a qualified mechanic to make sure that there is no damage.
