Sae Viscosity
WARNING: This page is about a different car, the 2009 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Fig 1 for the preferred engine oil viscosity grade for each vehicle. 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) temperature performance range of the oil.
