How is engine oil classified?

Based on the coldest temperature the oil passes at, that oil is graded as SAE viscosity grade 0W, 5W, 10W, 15W, 20W, or 25W. The lower the viscosity grade, the lower the temperature the oil can pass.

Why are engine oils different?

Oils are graded according to their viscosity – basically how thick or thin they are. Viscosity changes with temperature. Engine oils are ‘multi-grade’ to cope with a wide range of operating temperatures. Additives (viscosity improvers) give the oil one viscosity when it’s cold and another when it’s hot.
