Required fuel
Premium unleaded gasoline
The minimum Octane Rating is 91.
If you use gasoline with this minimum Octane 
Rating, the engine may produce knocking 
sounds when starting at high outside tempera-
tures. This has no effect on the engine life.
Minimum Octane Rating corresponds to the 
Anti Knock Index AKI and is determined accord-
ing to the so-called (R+M)/2 method.
Use high-quality brands
Field experience has demonstrated significant 
differences in fuel quality: volatility, composi-
tion, additives, etc., among gasolines offered for 
sale in the United States and Canada. Fuels 
containing 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 
problems relating to drivability and start-
ing, and to a tendency to stall, especially under 
certain environmental conditions such as high 
ambient temperature and high altitude. 
Should you encounter drivability 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. 
Failure to comply with these recommendations 
may also result in unscheduled maintenance.
