E-85 fuelE-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV) . Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispensing
pumps to be identified by a small, square,
orange and black label with the common
abbreviation or the appropriate percentage for
that region.Aftermarket fuel additivesNISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel
injector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold commer-
cially. Many of these additives intended for gum,
varnish or deposit removal may contain active
solvent or similar ingredients that can be harmful
to the fuel system and engine.Octane rating tipsUsing unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy “spark knock”. (Spark
knock is a metallic rapping noise.) If
severe, this can lead to engine damage. If
you detect a persistent heavy spark knock
even when using gasoline of the stated
octane rating, or if you hear steady spark
knock while holding a steady speed on
level roads, have a NISSAN dealer correctthe condition. Failure to correct the condi-
tion is misuse of the vehicle, for which
NISSAN is not responsible.
Incorrect ignition timing will result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are
encountered, have your vehicle checked at a
NISSAN dealer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.9-4

COMMENDATION
Selecting the correct oilIt is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance, see
“CAPACITIES AND RECOMMENDED FUEL/
LUBRICANTS” earlier in this section. NISSAN
recommends the use of an energy conserving oil
in order to improve fuel economy.
Select only engine oils that meet the American
Petroleum Institute (API) certification or Interna-tional Lubricant Standardization and Approval
Committee (ILSAC) certification and SAE vis-
cosity standard. These oils have the API
certification mark on the front of the container.
Oils which do not have the specified quality
label should not be used as they could cause
engine damage.
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 followed.
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
to select the engine oil viscosity based on the
temperatures at which the vehicle will be
operated before the next oil change. Choosing
an oil viscosity other than that recommended
could cause serious engine damage.Selecting the correct oil filterYour new NISSAN vehicle is equipped with a
high-quality genuine NISSAN oil filter. When
replacing, use a genuine NISSAN oil filter or its
equivalent for the reason described in “Change
intervals”.Change intervalsThe oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Using an engine oil and
filter other than the specified quality, or exceed-
ing recommended oil and filter change intervals
could reduce engine life. Damage to the engine
caused by improper maintenance or use of
incorrect oil and filter quality and/or viscosity is
not covered by the NISSAN new vehicle limited
warranty.
Your engine was filled with a high quality engine
oil when it was built. You do not have to change
the oil before the first recommended change
interval. Oil and filter change intervals depend
