What do Motor Oil Viscosity Ratings Mean?

When you’re trying to figure out the correct type of motor oil to get for your vehicle, bear in mind that oil viscosity refers to the fluid’s thickness. Think about the season and the type of driving you’ll be doing. Next, remember a couple of basic principles: if oil is too thin, it won’t be able to properly lubricate the parts; too thick, and it’s harder work for the engine.

The multi-grade bottle’s numbers tell you what that specific oil’s viscosity is in both cold and hot weather. Take a 5W30 oil, for example, the 5 is the maximum viscosity, or thickness, of the oil in cold weather. You want a lower number in cold weather, so it can flow through the engine quicker. The W means winter. The 30 tells you the viscosity range that the oil needs to be within during hot weather or when the engine is warmed up.
