octane FORD F150 1997 10.G Owners Manual

vehicle. The damage may not be
covered by your warranty.
Your vehicle was not designed to
use fuel containing
manganese-based additives such as
MMT. Additionally, vehicles
certified to California emission
standards (indicated on the
underhood Vehicle Emissions
Control Information label) are
designed to operate on California
reformulated gasolines. If
California reformulated gasoline is
not available when you refuel, your
vehicle can be operated on
non-California fuels. However, even
though your engine will perform
adequately on other gasolines, the
performance of the emission
control devices and systems may
be adversely affected. Repair of
damage caused by using a fuel that
your vehicle was not designed for
may not be covered by your
warranty.
Octane recommendations
Your vehicle is designed to use
regular gasoline with an (R+M)/2
octane rating of 87. We do not
recommend gasolines labeled as
ªregularº in high altitude areas that
are sold with octane ratings of 86
or even less.
Do not be concerned if your
vehicle sometimes knocks lightly.
However, if it knocks heavily under
most driving conditions on the
recommended octane fuel, see
