Fuel
Use of the recommended fuel is an important part of the proper maintenance of this vehicle. To help keep the engine clean and maintain optimum vehicle performance, we recommend the use of gasoline advertised as TOP TIER Detergent Gasoline.
Look for the TOP TIER label on the fuel pump to ensure gasoline meets enhanced detergency standards developed by auto companies. A list of marketers providing TOP TIER Detergent Gasoline can be found at www.toptiergas.com.
The 8th digit of the Vehicle Identification Number (VIN) shows the code letter or number that identifies the vehicle’s engine. The VIN is at the top left of the instrument panel. See Vehicle Identification Number (VIN).
If the vehicle has the 3.9L V6 engine (VIN Code M), you can use either unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85). See Fuel E85 (85% Ethanol). In all other engines, use only the unleaded gasoline described under Gasoline Octane .
