How 2 Stroke Oil Works

Four-cycle engines have a closed crankcase, which is what makes them different from two-cycle engines. Crankcase compression two-stroke engines require a different type of oil than a four-cycle engine because of this reason. Since these types of engines use the crankcase as part of the induction tract, gasoline and oil must be mixed for proper lubrication.

Generally, the best way to do this is to use 2 stroke oil, which is offered by many of the top motor oil brands. This type of oil is burned alongside the fuel in what is technically a total-loss oiling system, though it is rarely referred to as such, because two-stroke engines differ greatly from other total-loss oiling systems that are used in steam engines.
