engine oil
Crankcase liquid gold
Engine oil is a lubricant used in internal combustion engines to reduce friction between moving parts, dissipate heat, and prevent corrosion.
Also called motor oil.
Different vehicles require different viscosity grades: Check your owner's manual before choosing an engine oil.
Regular oil changes are essential maintenance for any gasoline or diesel engine.
