Fuel specifications

Do not fill the tank with leaded fuel, as this
would cause damage to the catalytic con-
verter.
Do not fill the tank with E85, i.e. fuel containing
85% ethanol, nor with FlexFuel. Otherwise the
engine and fuel supply system will be dam-
aged.<
Required fuel
Super Premium gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is 87.
If you use gasoline with this minimum AKI Rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures. This
has no effect on the engine life.
Do not use any gasoline below the speci-
fied minimum fuel grade. Otherwise the
engine could be damaged.<
Use high-quality brands
Field experience has indicated significant
differences in fuel quality: volatility, composi-
tion, additives, etc., among gasolines offered for
sale in the United States and Canada. Fuels con-
taining up to and including 10% ethanol or
other oxygenates with up to 2.8% oxygen by
weight, that is, 15% MTBE or 3% methanol plus
an equivalent amount of co-solvent, will not
void the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
driveability, starting and stalling problems
especially under certain environmental condi-

tions such as high ambient temperature and
high altitude.
Should you encounter driveability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<
