Reading Engine Oil Ratings

Engine oil is an essential layer of protection for engine parts. When operating, the engine's moving parts produce heat from friction and the burning of fuel. The engine oil absorbs heat, and it coats the critical moving parts.

Drivers know that without engine oil or the right engine oil, the heat will damage and ruin the motor. Engine oil must work in warm and cold conditions, and it flows at different rates when in warm versus cold air. The engine oil rating describes the flow in cold and warm temperatures. For example, 10 W 30 oil flows at a 10 rating in cold air and a 30 rating when in warm air.
