Example, 5/20 refers to the viscosity of oil at different temperatures. At cold temperatures, below freezing, the "viscosity" of the oil is "5" weight, meaning it is thinner and will flow easier. At higher temperatures, the oil is "20" weight meaning it is a little thicker to provide adequate lubrication. Lower viscosity oils may provide better fuel economy since being thinner will allow it to flow more easily. Refer to your owners manual for the proper viscosity of oil for you particular car/truck.
