NISSAN 2008 Sentra - Manual (Page 287)

FUEL RECOMMENDATION
MR20DE and QR25DE engine except Spec-V
Use unleaded regular gasoline with an octane
rating of at least 87 AKI (Anti-Knock Index) num-
ber (Research octane number 91).
QR25DE engine Spec-V only
Use unleaded premium gasoline with an octane
rating of at least 91 AKI (Anti-Knock Index) num-
ber (Research octane number 96).
If unleaded premium gasoline is not available,
unleaded regular gasoline with an octane rating
of at lease 87 AKI (Research octane number 91)
can be used, but only under the following precau-
tions:
● have the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium as soon as possible.
● avoid full throttle driving and abrupt accel-
eration.
However, for maximum vehicle perfor-
mance, the use of unleaded premium gaso-
line is recommended.
CAUTION
● Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect the
warranty coverage.
● Under no circumstances should a
leaded gasoline be used, because this
will damage the three-way catalyst.
● Do not use E-85 fuel in your vehicle.
Your vehicle is not designed to run on
E-85 fuel. Using E-85 fuel can damage
the fuel system components and is not
covered by the NISSAN new vehicle lim-
ited warranty.
Gasoline specifications
NISSAN recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifi-
cations where it is available. Many of the automo-
bile manufacturers developed this specification
to improve emission control system and vehicle
performance. Ask your service station manager if
the gasoline meets the WWFC specifications.
Reformulated gasoline
Some fuel suppliers are now producing reformu-
lated gasolines. These gasolines are specially
designed to reduce vehicle emissions. NISSAN
supports efforts towards cleaner air and sug-
gests that you use reformulated gasoline when
available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing oxy-
genates such as ethanol, MTBE and methanol
with or without advertising their presence.
NISSAN does not recommend the use of fuels of
which the oxygenate content and the fuel com-
patibility for your NISSAN cannot be readily de-
termined. 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.
● The fuel should be unleaded and have
an octane rating no lower than that
recommended for unleaded gasoline.
● If an oxygenate-blend other than
methanol blend is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
● 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
