Prohibited Fuels

Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:
Fuel with any amount of
methanol, methylal, ferrocene,
and aniline. These fuels can
corrode metal fuel system
parts or damage plastic and
rubber parts.
Fuel containing metals such
as methylcyclopentadienyl
manganese tricarbonyl
(MMT), which can damage
the emissions control system
and spark plugs.
Fuel with a posted octane
rating of less than the
recommended fuel. Using this
fuel will lower fuel economy
and performance, and may
decrease the life of the
emissions catalyst.

Fuel Additives

TOP TIER Detergent Gasoline is highly
recommended for use with your
vehicle. If your country does not have
TOP TIER Detergent Gasoline, add
ACDelco Fuel System Treatment
Plus-Gasoline to the vehicle s gasoline
fuel tank at every oil change or
15 000 km (9,000 mi), whichever
occurs first. TOP TIER Detergent
Gasoline and ACDelco Fuel System
Treatment Plus-Gasoline will help
keep your vehicle s engine fuel deposit
free and performing optimally. If you
are unable to obtain ACDelco Fuel
System Treatment Plus - Gasoline,
consult your dealer for the GM
approved additive available in your
country.
