Choosing the Right Fuel
We recommend regular unleaded gasolinewith a pump octane rating of 87. Somestations offer fuels posted as regular withan octane rating below 87, particularly inhigh altitude areas. We do not recommendfuels with an octane rating below 87.Premium unleaded gasoline will provideimproved performance and isrecommended for severe duty usage, forexample a fully loaded vehicle.
Do not use any fuel other than thoserecommended because they could lead toengine damage that may not be coveredby the vehicle Warranty.
Note:Use of any fuel other than thoserecommended can impair the emissioncontrol system and cause a loss of vehicleperformance.
Do not use:
•Diesel fuel.
•Kerosene or paraffin fuels.
•Fuel containing more than 15% ethanolor E-85 fuel.
•Fuels containing methanol.
•Fuels containing metallic-basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel (using leaded fuel isprohibited by law).
The use of fuels with metallic compoundssuch as methylcyclopentadienylmanganese tricarbonyl (commonly knownas MMT), which is a manganese-basedfuel additive, will impair engineperformance and affect the emissioncontrol system.
Do not be concerned if the enginesometimes knocks lightly. However, if itknocks heavily under most drivingconditions while you are using fuel with therecommended octane rating, contact anauthorized dealer to prevent any enginedamage.
