the Anti Knock Index AKI and is deter-

Use high-quality brands
Field experience has indicated signifi-
cant differences in fuel quality: volatility,
composition, 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% meth-
anol 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 drivability, starting and
stalling problems, especially under cer-
tain environmental conditions such as
high ambient temperature and high alti-
tude.
Should you encounter drivability prob-
lems that you suspect could be related
to the fuel you are using, we recom-
mend that you respond by switching to
a recognized high-quality brand.
Failure to comply with these recom-
mendations may also result in unsched-
uled maintenance.
