What are the different types of motor oil?

Motor oil is divided into four types, as well as a range of viscosities:

Conventional motor oil  is derived directly from crude oil, and is recommended for those with non-high performance cars and average driving habits.

Synthetic motor oil  is chemically engineered for better performance, especially in extreme temperatures.

Synthetic blend motor oil  is a mixture of conventional and synthetic motor oils that has high oxidation resistance and excellent performance in low temperatures.

High-mileage motor oil  is specially formulated to reduce burn-off and minimize leaks in vehicles with more than 75,000 miles.

Viscosity  refers to the oil’s resistance to flow, and is marked on the package with a cold weather (designated by the letter W for winter) viscosity and a high temperature viscosity. A lower number means better cold weather performance, while a higher number means better warm weather performance. For example, 5W-30 motor oil performs better in winter than 10W-30 oil, while 10W-40 oil performs better in hot weather than 10W-30. Ask your auto technician or check your owner’s manual to determine which viscosity is right for you.
