Selection Of Engine Oil
For best performance and protection of your vehicle, use
only crankcase engine oils that meet the following re-
quirements:
• Engine Oil Selection for Operating on E-85
If you operate the vehicle on E-85 fuel either full or
part-time, use only Mopar Flexible Fuel 5W-30 engine
oil (P/N 4318086) or an equivalent that meets
DaimlerChrysler Standard MS-9214. Equivalent com-
mercial 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
DaimlerChrysler Standard.
The 5W-30 engine oil installed at the factory meets the
DaimlerChrysler requirements for Flexible Fuel engine
oil.
SAE 5W-30 engine oil is preferred for use in Flexible Fuel
engines.
CAUTION!
If Flexible Fuel engine oil is not used when using
E-85, engine wear may be increased significantly.
This may void your warranty.
• Engine Oil Selection for Operating on Gasoline
If you operate the vehicle on regular unleaded gasoline
ONLY, use Mopar oil or an equivalent that meets certified
API (American Petroleum Institute) Quality.
