Use high-quality brands
Field experience has indicated significant 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% methanol plus an equivalent equivalent amount of co-solvent, will not void the applicable warranties with respect to defects in materials or workmanship.
Minimum fuel grade
The use of poor-quality fuels may result in
driveability, starting and stalling problems especially
under certain environmental conditions
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 result in unscheduled maintenance.◀
