MAINTAINING YOUR VEHICLE 209 Engine Oil Viscosity (SAE Grade) Flexible Fuel Engine Oil If you operate the vehicle on E-85 fuel either full or part-time, use only Mopar Flexible Fuel 5W-30 engine oil or an equivalent that meets the manufacturers Standard MS-9214. Equivalent commercial Flexible Fuel engine oils may be labeled as Flexible Fuel (FFV) or Alternate Fuel (AFV). These engine oils may be satisfactory if they meet the manufacturer's standard. CAUTION! If Flexible Fuel engine oil is not used when using E-85, engine wear may be increased significantly. This may void your warranty. Synthetic Engine Oils You may use synthetic engine oils provided that the recommended oil quality requirements are met and the recommended maintenance intervals for oil and filter changes are followed. Engine Oil Fill Cap 7 SAE 5W-20 and SAE 5W-30 engine oils are recommended for all operating temperatures. These 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. Lubricants which do not have both, the engine oil certification mark and the correct SAE viscosity grade number should not be used.
