5W-20 is second only to 5W-30 as the viscosity most recommended by automakers for vehicles over the past four decades. Most popular with American automakers, it’s also been a frequent choice of Asian automakers. A few European automakers call for it in their trucks and vans.

Some automakers have and are transitioning to 0W-20 oils for recent model year vehicles to help optimize fuel economy. And 0W-20 is increasingly being listed as an alternate choice for a 5W-20 oil.

What do the numbers in 5W-20 mean? The numbers refer to the weight and thickness, or viscosity, of the oil. Motor oil gets thicker when it’s cold and thinner when it heats up. The first number indicates the viscosity of the oil at a cold temperature, and the second number indicates the viscosity at operating temperatures.
