technical data NISSAN FRONTIER 1999 D22 / 1.G Owners Manual

FUEL RECOMMENDATION
Your vehicle is designed to operate on
unleaded gasoline with an octane rating
of at least 87 AKI (Anti-Knock Index)
(Research octane number 91).
CAUTION
IUsing a fuel other than that specified
could adversely affect the emission
control devices and systems, and
could also affect the warranty cover-
age.
IUnder no circumstances should a
leaded gasoline be used, since this
will damage the three-way catalyst.
Reformulated Gasoline
Some fuel suppliers are now producing re-
formulated gasolines. These gasolines are
specially designed to reduce vehicle emis-
sions. NISSAN supports efforts towards
cleaner air and suggests that you use refor-
mulated gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE andmethanol with or without advertising their
presence. Nissan does not recommend the
use of fuels of which the oxygenate content
and the fuel compatibility for your NISSAN
cannot be readily determined. If in doubt,
ask your service station manager.
If you use oxygenate-blend gasoline, please
take the following precautions as the usage
of such fuels may cause vehicle perfor-
mance problems and/or fuel system dam-
age.
IThe fuel should be unleaded and
have an octane rating no lower than
that recommended for unleaded
gasoline.
IIf an oxygenate-blend, excepting a
methanol blend, is used, it should
contain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
I
If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable
amount of appropriate cosolvents
and corrosion inhibitors. If not prop-
erly formulated with appropriate co-solvents and corrosion inhibitors,
such methanol blends may cause fuel
system damage and/or vehicle perfor-
mance problems. At this time, suffi-
cient data is not available to ensure
that all methanol blends are suitable
for use in NISSAN vehicles.
If any driveability problems such as engine
stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels,
immediately change to a non-oxygenate
fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygen-
ates can cause paint damage.
After Market Fuel Additives
NISSAN does not recommend the use of
any fuel additives (i.e., fuel injector cleaner,
octane booster, intake valve deposit remov-
ers, etc.) which are sold commercially. Many
of these additives intended for gum, varnish
or deposit removal may contain active sol-
vents or similar ingredients that can be
harmful to the fuel system and engine.
