How 2 Cycle Oil Works
Two-cycle engines have different requirements than four-cycle engines found in cars and lawn tractors. Oil and regular unleaded gasoline is blended together to create an enriched mixture that does more than just fuel an engine. For instance, two-cycle oil lubricates the engine while providing fuel.
When the mixture moves into the crankcase it pushes the piston up, creating a spark. Then, the spark ignites the fuel which sends the piston downwards. Thus, the power behind the two-cycle engine is created. A typical ration of oil to gas is 40 parts gasoline to one part oil or 50 parts gasoline to one part oil. Yamalube 2 cycle oil comes highly recommended.
