Check before you buy or refuel Confirm on the window sticker, owner's manual or with the dealer. Trims and options can differ from the configurations EPA tested.

About premium fuel EPA data shows the fuel a vehicle was tested on. It does not say whether premium is required or only recommended. Your owner's manual or fuel-door label is the authority.

Before using E85 Confirm the vehicle is a flex-fuel vehicle (FFV) in the owner's manual, or look for a yellow gas cap or an "FFV" badge. Not every version of a model is flex-fuel.
