as hard starting, stalling, and hesitations. If you experi-

ence these symptoms, try another brand of gasoline

before considering service for the vehicle.

Over 40 auto manufacturers worldwide have issued and

endorsed consistent gasoline specifications (the World-

wide Fuel Charter, WWFC) which define fuel properties

necessary to deliver enhanced emissions, performance,

and durability for your vehicle. The manufacturer recom-

mends the use of gasolines that meet the WWFC speci-

fications if they are available.

Reformulated Gasoline

Many areas of the country require the use of cleaner

burning gasoline referred to as "Reformulated Gasoline."

Reformulated gasoline contain oxygenates and are spe-

cifically blended to reduce vehicle emissions and im-

prove air quality.

The manufacturer supports the use of reformulated gaso-

line. Properly blended reformulated gasoline will pro-

vide excellent performance and durability of engine and

fuel system components.

Some fuel suppliers blend unleaded gasoline with oxy-

genates such as Ethanol.

DO NOT use gasoline containing Methanol or gaso-

line containing more than 10% Ethanol. Use of these

blends may result in starting and drivability prob-

lems, damage critical fuel system components, cause

emissions to exceed the applicable standard, and/or

cause the "Malfunction Indicator Light" to illumi-

nate. Pump labels should clearly communicate if a

fuel contains greater than 10% Ethanol.
