FUEL QUALITY
Choosing the Right Fuel
Use only premium unleaded gasoline witha minimum pump (R+M)/2 octane ratingof 91. For optimal performance, usepremium unleaded gasoline with an octanerating of 93 or higher.
The use of the correct fuel is an importantpart of the proper maintenance of yourvehicle, and a condition of the vehicleWarranty. For this vehicle, the use ofgasoline with an octane level of 91 orhigher is required. The use of gasoline withan octane rating lower than 91 willinvalidate the vehicle Warranty. It candegrade vehicle performance and lead tosevere mechanical damage.
Note:Use of any fuel other than thoserecommended can impair the emissioncontrol system and cause a loss of vehicleperformance.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuel containing more than 15% ethanolor E85 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.
