There are many brands of motor oil to choose from, but no matter which brand you choose, there’s one thing they all have in common: a combination of numbers and a letter that describes how thick the oil is – its viscosity.

The Society of Automotive Engineers came up with this combination, but how many of us know how to interpret that number – letter – number combination?

The staff at Advance Auto Parts can help you choose the correct engine oil for your needs, whether you’re shopping for your vehicle, lawn mowers or anything else that uses oil

Generally speaking, the lower the number, the lower the viscosity.

Let’s use 5W-30 as an example. This type of oil is used commonly in newer model vehicles.

The number before the W describes the thickness of the oil at low temperatures. The lower the number, the thinner the oil and the better that oil will perform when the engine is cold.

The number after the W describes the oil’s thickness when the engine’s warmed up. Higher numbers mean thicker oil viscosity, which provides better protection for high-heat or high-load uses.

Trust the staff at Advance Auto to help you choose the right product for your needs.
