Engine Oil

An SAE viscosity grade is used to specify the viscosity of engine oil. Use only engine oils with multiple viscosities such as 5W-30 or 10W-30. These are specified with a dual SAE viscosity grade which indicates the cold-to-hot temperature viscosity range. Select an engine oil that is best suited to your particular temperature range and variation.

For 3.7L engines SAE 5W-30 engine oil is recommended for all operating temperatures. These engine oils improve low temperature starting and vehicle fuel economy. Refer to your engine oil filler cap for the recommended engine oil viscosity for your vehicle. Refer to the engine oil filler cap for the recommended engine oil viscosity for each vehicle.
