FUEL RECOMMENDATION (for
QR25DE models)
Use unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).

WARNING
∙ Ethanol vapors are extremely flam-mable and could cause serious per-
sonal injury.
∙ Never have any smoking materials lit in or near the vehicle when removing
the fuel filler cap or filling the tank.
∙ Do not use E-85 as a cleaning agent and never use it near an open flame.
Fuel requirements
Your vehicle will operate on both unleaded
regular gasoline with an octane rating of at
least 87 AKI (Anti-Knock Index) number (Re-
search octane number 91), or E-85 fuel, or
any mixture of these two.
For the best starting and vehicle driveabil-
ity results, do not continually switch be-
tween E-85 and unleaded regular gasoline.
If you must switch fuels, NISSAN recom-
mends the following: ∙ do not switch when the fuel gauge indi- cates less than 1/4 full
∙ add more than 5 gallons of fuel
∙ operate the vehicle immediately af ter refueling for a period of at least 5 min-
utes NOTE:
When the ambient temperature is above
90°F (32°C), you may experience hard
starting and rough idle following start
up even if the above recommendations
are followed.
Starting
The characteristics of E-85 fuel make it un-
suitable for use when ambient tempera-
tures fall below 0°F (-18°C). In the range of
0°F (-18°C) to 32°F (0°C), you may experience
an increase in the time it takes for you en-
gine to start, and a deterioration in drivabil-
ity (sags and/or hesitations) until the en-
gine is fully warmed up.
Fuel consumption
Because E-85 fuel contains less energy per
gallon than gasoline, you will experience an
increase in fuel consumption. You can ex-
pect your fuel mileage to decrease by
about 30% compared to gasoline opera-
tion.
Replacement parts
Many components in your Flexible Fuel Ve-
hicle (FFV) are designed to be compatible
with ethanol. Always be sure that your ve-
hicle is serviced with correct ethanol com-
patible parts.
