What's The Difference Between A 2 Stroke And A 4 Stroke Engine?
2 stroke engines use a crankcase to pressurize the air-fuel mixture before transfer to the cylinder. Unlike 4 stroke engines, they cannot be lubricated by oil contained in the crankcase and sump: lubricating oil would be swept up and burnt with the fuel. Fuels supplied to 2 stroke engines are mixed with oil so that it can coat the cylinders and bearing surfaces along its path. The ratio of petrol to oil ranges from 10:1 to 50:1 by volume.
The precise 2 stroke oil ratio depends on your manufacturer’s instructions, as each engine can have varied requirements. If you put too much oil, it can generate additional carbon build-up, making it difficult to start the engine.
Marine and automotive engine oils are not interchangeable. The two primary reasons for this are water and wear. Consider that corrosion caused by water is a primary concern for marine engines.
