technical data NISSAN SENTRA 2002 B15 / 5.G Owners Manual

FUEL RECOMMENDATION
For 1.8L/2.5L engines
Use unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
For SE-R SPEC V
Use unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
For improved vehicle performance, NISSAN
recommends the use of unleaded premium
gasoline with an octane rating of at least 91
AKI number (Research octane number 96).
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 con-
tain 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 corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system dam-age and/or vehicle performance prob-
lems. At this time, sufficient data is
not available to ensure that all metha-
nol blends are suitable for use in NIS-
SAN 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.
Aftermarket 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
of at least 87 AKI (Anti-Knock Index). How-
