[DelFinley]

Naturally aspirated engines can use 5w20, 0w20, 5w30, or 0w30 engine oil. Introduction to Engine Oil: Engine oil is something every car owner will come into contact with during vehicle use. It is often referred to as the lifeblood of the engine, as the engine cannot operate properly without it. Functions of Engine Oil: Inside the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. When the engine is running, the oil forms a thin film on the surfaces of various components, preventing direct contact and friction between them.
