FUEL RECOMMENDATION
VQ35DE engine
INFINITI recommends the use of unleaded
premium gasoline with an octane rating of
at least 91 AKI (Anti-Knock Index) number
(Research octane number 96).
If unleaded premium gasoline is not avail-
able, you may use unleaded regular gaso-
line with an octane rating of at least 87
AKI number (Research octane number 91),
but you may notice a decrease in perfor-
mance.
VK45DE engine
Use unleaded premium gasoline with an
octane rating of at least 91 AKI (Anti-
Knock Index) number (Research octane
number 96).
If unleaded premium gasoline is not avail-
able, unleaded regular gasoline with an
octane rating of at least 87 AKI number
(Research octane number 91) can be used,
but only under the following precautions:
O
Have the fuel tank filled only partially
with unleaded regular gasoline, and
fill up with unleaded premium gaso-
line as soon as possible.
O
Avoid full throttle driving and abrupt
acceleration.
However, for maximum vehicle perfor-
mance, the use of unleaded premium gaso-
line is recommended.
CAUTION
O
Using a fuel other than that specified
could adversely affect the emission con-
trol system, and may also affect the war-
ranty coverage.
O
Under no circumstances should a leaded
gasoline be used, because this will dam-
age the three-way catalyst.
O
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 INFINITI vehicle limited warranty.
Gasoline specifications
INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter
(WWFC) specifications where it is avail-
able. Many of the automobile manufactur-
ers developed this specification to im-
prove emission system and vehicle perfor-
mance. Ask your service station manager
if the gasoline meets the WWFC specifica-
tions.
Reformulated gasoline
Some fuel suppliers are now producing
reformulated gasolines. These gasolines
are specially designed to reduce vehicle
emissions. INFINITI supports efforts to-
wards cleaner air and suggests that you
use reformulated gasoline when avail-
able.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline contain-
ing oxygenates such as ethanol, MTBE
and methanol with or without advertising
their presence. INFINITI does not recom-
mend the use of fuels of which the oxy-
genate content and the fuel compatibility
for your INFINITI cannot be readily deter-
mined. If in doubt, ask your service sta-
tion 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.
