The primary function of car oil is to lubricate the engine. This helps the moving parts of the engine to work smoothly, reducing friction. When friction is reduced, it prevents the parts from wearing out too quickly. Here’s how oil helps:

Lubrication: The oil forms a thin film between the engine’s moving parts. This helps to reduce the friction that could cause damage over time.
Cooling: Oil helps to absorb heat from the engine, preventing it from overheating. This helps to keep the engine at an optimal temperature.
