Understanding Oil Viscosity Ratings

Motor oil must flow as soon as the engine cranks to protect the moving parts. It reduces friction and absorbs excess engine heat. The thickness of the oil determines the rate at which it flows. Thick oil flows slower and has a high viscosity number. Thinner oils flow more quickly and work well to protect engines in low temperatures. The rating uses the low-temperature number, the letter W, and the warm temperature number. For example, 10 W 30 is a popular blend.

Drivers know that regular oil changes will prolong the life of their engines and reduce wear and tear. Regular oil changes must meet the manufacturer's recommendation for the type of oil and the frequency of changes.
