oxygen NISSAN SENTRA 1997 B14 / 4.G Owners Manual

FUEL RECOMMENDATION
All models are designed to operate on
unleaded gasoline with an octane rating
of at least 87 AKI (Anti-Knock Index)
(Research octane number 91).
CAUTION
cUsing a fuel other than that specified
could adversely affect the emission
control devices and systems, and
could also affect the warranty
coverage.
cUnder 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 performance
problems and/or fuel system damage.
cThe fuel should be unleaded and
have an octane rating no lower than
that recommended for unleaded
gasoline.
cIf an oxygenate-blend other than a
methanol blend is used, it should
contain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
cIf 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
performance problems. At this time,
sufficient data is not available to en-
sure that all methanol blends are suit-
able 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 cleaners,
octane boosters, intake valve deposit re-
movers, etc.) which are sold commercially.
Many of these additives intended for gum,
varnish or deposit removal may contain ac-
tive solvents or similar ingredients that can
be harmful to the fuel system and engine.
Octane rating tips
In most parts of North America, you should
use unleaded gasoline with an octane rating
9-3
