9 Technical and consumer information

FUEL INFORMATION
VR38 engineUse unleaded premium gasoline with an
octane rating of at least 93 AKI (Anti-
Knock Index) number (Research octane
number 98) to maximize vehicle perfor-
mance.
If the premium gasoline specified above is
not available, you may use unleaded
premium gasoline with an octane rating
of at least 91 AKI number (Research
octane number 96), but you may notice
a decrease in performance.
Do not use gasoline with an octane rating
lower than 91 AKI (Research octane num-
ber 96).
NOTICE

use reformulated gasoline when avail-
able.Gasoline containing oxygenates
NOTICE
Take care not to spill gasoline during
refueling. Gasoline containing oxy-
genates can cause paint damage.E-15 fuelE-15 fuel is a mixture of approximately
15% fuel ethanol and 85% unleaded gaso-
line. E-15 can only be used in vehicles
designed to run on E-15 fuel. Do not use E-
15 in your vehicle. U.S. government reg-
ulations require fuel ethanol dispensing
pumps to be identified with small, square,
orange and black label with the common
abbreviation or the appropriate percen-
tage for that region.E-85 fuelE-85 fuel is a mixture of approximately
85% fuel ethanol and 15% unleaded gaso-
line. E-85 can only be used in a Flexible
Fuel Vehicle (FFV). Do not use E-85 fuel in
your vehicle. U.S. government regulations
require fuel ethanol dispensing pumps to
be identified by a small, square, orange
and black label with the common abbre-
viation or the appropriate percentage for
that region.Technical and consumer information
9-5

Fuel containing MMTMMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting
additive. NISSAN does not recommend
the use of fuel containing MMT. Such fuel
may adversely affect vehicle perfor-
mance, including the emissions control
system. Note that while some fuel pumps
label MMT content, not all do, so you may
have to consult your gasoline retailer for
more details.Aftermarket fuel additives
NOTICE
NISSAN does not recommend the use
of any aftermarket fuel additives
(Example: fuel injector cleaner, in-
take valve deposit removers, etc.)
which are sold commercially. Many
of these additives intended for gum,
varnish or deposit removal may con-
tain active solvent or similar ingre-
dients that can be harmful to the fuel
system and engine.

Oil additivesNISSAN does not recommend the use of
oil additives. The use of an oil additive is
not necessary when the proper oil type is
used and maintenance intervals are fol-
lowed.
Oil which may contain foreign matter or
has been previously used should not be
used.Oil viscosityThe engine oil viscosity or thickness
changes with temperature. Because of
this, it is important that the engine oil
viscosity be selected based on the tem-
peratures at which the vehicle will be
operated before the next oil change.
Choosing an oil viscosity other than that
recommended could cause serious en-
gine damage.Selecting the correct oil filterYour new vehicle is equipped with a high-
quality genuine NISSAN oil filter. NISSAN
recommends to use the genuine NISSAN
oil filter for the reason described in
change intervals.
