octane FORD TAURUS 1998 3.G Owners Manual

Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel
is prohibited by law and could damage your vehicle.
Your vehicle was not designed to use fuel or fuel
additives with metallic compounds, including
manganese-based compounds containing (MMT).
Vehicles certified to meet 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 for which
your vehicle was not designed may not be covered
by your warranty.
Octane recommendations
3.0L V6 Vulcan and Duratec engines
Your vehicle is
designed to use
ªRegularº unleaded
gasoline with an
(R+M)/2 octane rating of 87. We do not recommend
the use of gasolines labeled as ªRegularº that are
sold with octane ratings of 86 or lower in high
altitude areas.
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 dealer or
a qualified service technician to prevent any engine
damage.

3.4L-32V V8 SHO engine
Your vehicle is
designed to use
ªPremiumº gasoline
with an (R+M)/2
octane rating of 91 or higher for optimum
performance. Gasolines with lower octane ratings
can be used, but performance may decrease. We do
not recommend the use of gasolines labeled as
ªPremiumº in high altitude areas that are sold with
octane ratings of less than 91.
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 dealer or
a qualified service technician to prevent any engine
damage.
Fuel quality
If you are experiencing starting, rough idle or
hesitation driveability problems during a cold start,
try a different brand of gasoline. ªPremiumº
unleaded gasoline should not be used (particularly in
the United States) if ªRegularº unleaded gasoline is
recommended because it may cause these problems
to become more pronounced. If the problems
persist, see your dealer or a qualified service
technician.
The American Automobile Manufacturers Association
(AAMA) issued a fuel specification to provide
information on high quality fuels that optimize the
performance of your vehicle. We recommend the use
of fuels that meet the AAMA specification if they are
available.
It should not be necessary to add any aftermarket
products to your fuel tank if you continue to use a
high-quality fuel.
