Two-stroke oil is different from regular motor oil. It is thin and specifically made to mix with gasoline in the gas tank of two-stroke engines. This is how the piston is lubricated in a two-stroke engine. Two-cycle oil is regular motor oil that you put in the oil filler hole on an automobile engine.
Four-stroke oil is more like the oil used in cars but both 2-stroke and 4-stroke oil serve the same purpose - to keep the engine lubricated. Four-stroke dirt bike oil comes in a variety of weights like 10w-40, 20w-50 and so on. It is not mixed with gas.
