Jeep Liberty: Engine Oil Viscosity
SAE 5W-20 engine oil is recommended for all operating temperatures. This engine oil improves low temperature starting and vehicle fuel economy. The engine oil filler cap also shows the recommended engine oil viscosity for your engine. For information on engine oil filler cap location, refer to “Engine Compartment” in “Maintaining Your Vehicle” for further information.
Lubricants which do not have both the engine oil certification mark and the correct SAE viscosity grade number should not be used.
