What Do Motor Oil Viscosity Ratings Mean?

Understanding a little about the motor oil you use in your vehicle and following the manufacturer’s guidelines will save you headaches in the long run. Viscosity is often used with motor oil. It simply means the thickness of the liquid, which in this case is oil. An oil’s viscosity that’s is too low, or thin, can’t lubricate the engine’s parts appropriately. When it’s too thick, or has a higher viscosity, it causes the engine to work too hard.

A multi-grade bottle of oil has two numbers separated by a W on it. The first number represents the highest viscosity the oil will reach in cold conditions. A 5 in 5W30, for example, needs to be low viscosity so that it can flow more easily to the engine’s parts in cold weather or when the engine’s cold. The W means winter. The 30 in this instance indicates the highest viscosity the oil will reach at 212 degrees. Hotter conditions require a thicker liquid.
