OCTANE RECOMMENDATIONS
Regular unleaded gasoline with a
pump (R+M)/2 octane rating of 87 is
recommended. Some stations offer
fuels posted asRegularwith 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 usage such as trailer tow.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.

TIRE ROTATION
Because your vehicle’s tires perform
different jobs, they often wear
differently. To make sure your tires
wear evenly and last longer, have
them rotated.Note:The F-150
Raptor requires tire rotations every
5,000 miles (8,000 km). If you
notice that the tires wear unevenly,
have them checked.
SPARE TIRE AND WHEEL
Your vehicle is equipped with an LT315/70R17 spare tire. The spare
tire/wheel assembly has the same capability as the road tire/wheel
assembly, but is not equipped with a tire pressure monitoring sensor.
