Note:   We recommend that you use only high quality fuel without additives or other engine treatments.
Choosing the Right Fuel
Note:   Use of any fuel other than those recommended may cause powertrain damage, a loss of vehicle performance and repairs may not be covered under warranty.
If your vehicle is not a flexible fuel vehicle, then only use unleaded fuel or unleaded fuel blended with a maximum of 15% ethanol. Do not use fuel ethanol (E85), diesel fuel, fuel methanol, leaded fuel or any other fuel because it could damage or impair the emission control system.
The use of leaded fuel is prohibited by law.
Your vehicle was not designed to use fuel or fuel additives with metallic compounds, including manganese-based additives.
Octane Recommendations
Regular unleaded gasoline with a pump (R+M)/2 octane rating of 87 is recommended. Some fuel stations offer fuels posted as regular with an octane rating below 87, particularly in high altitude areas. Fuels with octane levels below 87 are not recommended. Premium fuel will provide improved performance and is recommended for severe duty use such as trailer tow.
Do not be concerned if your engine sometimes knocks lightly. However, if it knocks heavily while you are using fuel with the recommended octane rating, see your authorized dealer to prevent any engine damage.
