Sae Viscosity
Engine oils are designed to improve low temperature starting and vehicle fuel economy. Refer to the engine oil filler cap for the preferred engine oil viscosity grade for each vehicle. Refer to Fig 1 SAE viscosity grades are used to specify the correct viscosity oil for an engine. Use only Multi-Viscosity oils. These are specified with a dual SAE viscosity grade which indicates the cold (5W) to hot (20, 30) temperature performance range of the oil.
