FUEL RECOMMENDATION
VK45DE engine
Use unleaded premium gasoline with an octane
rating of at least 91 AKI (Anti-Knock Index)
number (Research octane number 96).
If premium gasoline is not available, unleaded
regular gasoline with an octane rating of 87 AKI
number (Research octane number 91) may be
temporarily used, but only under the following
precautions:
●
Have the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as pos-
sible.
●
Avoid full throttle driving and abrupt accel-
eration.
However, for maximum vehicle performance, the
use of unleaded premium gasoline is recom-
mended.
VQ35DE engine
INFINITI recommends the use of unleaded pre-
mium gasoline with an octane rating of at least
91 AKI (Anti-Knock Index) number (Research
octane number 96).
If unleaded premium gasoline is not available,
you may use unleaded regular gasoline with an
octane rating of at least 87 AKI number (Re-
search octane number 91), but you may notice a
decrease in performance.
CAUTION
●
Using a fuel other than that specified could
adversely affect the emission control sys-
tem, and may also affect 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
INFINITI new vehicle limited warranty.
Gasoline specifications
INFINITI recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifica-
tions where it is available. Many of the automo-
bile manufacturers developed this specification
to improve the emission control system and
vehicle performance. Ask your service station
manager if the gasoline meets the WWFC speci-
fications.
Reformulated gasoline
Some fuel suppliers are now producing refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
INFINITI supports efforts towards cleaner air
and suggests that you use reformulated gaso-
line when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and metha-
nol with or without advertising their presence.
INFINITI does not recommend the use of fuels of
which the oxygenate content and the fuel com-
patibility for your INFINITI 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 prob-
lems and/or fuel system damage.
●
The fuel should be unleaded and have an oc-
tane rating no lower than that recommended
for unleaded gasoline.
●
If an oxygenate-blend other than methanol
blend is used, it should contain no more than
10% oxygenate. (MTBE may, however, be
added up to 15%.)
