STARTING AND OPERATING
Over 40 auto manu factu rer’s world wide have issu ed and
end orsed consistent gasoline specifications (the World -
wide Fuel Charter, WWFC) to define fuel prop erties
necessary to deliver enhanced emissions, perform ance,
and durability for you r vehicle. The manu factu rer recom -
mend s the use of gasoline that meets the WWFC speci-
fications if they are available.
winter months to red uce carbon monoxid e emissions.
Fuels blend ed with these oxygenates may be used in
you r vehicle.
CAUTIO N!
DO NOT use gasolin e contain ing METHANOL.
Gasolin e contain ing meth anol may damage critical
fuel system components.
Reformulated Gasoline
Many areas of the country requ ire the use of cleaner

MMT In Gasoline
MMT is a manganese containing metallic additive that is
blend ed into som e gasoline to increase octane. Gasoline
blend ed with MMT provid es no perform ance advantage
beyond gasoline of the sam e octane nu mber withou t
MMT. Gasoline blend ed with MMT red uces spark plug
life and red uces emission system perform ance in som e
vehicles. The manu factu rer recom mend s that gasoline
withou t MMT be used in you r vehicle. The MMT content
of gasoline may not be ind icated on the gasoline pump,
therefore, you shou ld ask you r gasoline retailer whether
or not his/ her gasoline contains MMT.
The manu factu rer strongly supports the use of reform u-
lated gasoline. Prop erly blend ed reform ulated gasoline
will provid e excellent perform ance and durability for the
engine and fuel system components.
