Caution (Continued)
.Fuel with a posted octanerating of less than therecommended fuel. Usingthis fuel will lower fueleconomy and performance,and may decrease the life ofthe emissions catalyst.
California Fuel
Requirements
If the vehicle is certified to meetCalifornia Emissions Standards, it isdesigned to operate on fuels thatmeet California specifications. Seethe underhood emission controllabel. If this fuel is not available instates adopting California EmissionsStandards, the vehicle will operatesatisfactorily on fuels meetingfederal specifications, but emissioncontrol system performance may beaffected. The malfunction indicatorlamp could turn on and the vehiclemay not pass a smog-check test.SeeMalfunction Indicator Lamp(Check Engine Light)0138.Ifthis
occurs, return to your authorizeddealer for diagnosis. If it isdetermined that the condition iscaused by the type of fuel used,repairs may not be covered by thevehicle warranty.
Fuels in Foreign
Countries
The U.S., Canada, and Mexico postfuel octane ratings in anti-knockindex (AKI). For fuel not to use in aforeign country, see“ProhibitedFuels”inFuel0311.
Fuel Additives
To k e e p f u e l s y s t e m s c l e a n , T O PTIER Detergent Gasoline isrecommended. SeeFuel0311.
If TOP TIER Detergent Gasoline isnot available, one bottle of GM FuelSystem Treatment Cleaner added tothe fuel tank at every engine oilchange, can help. GM Fuel SystemTreatment Cleaner is the onlygasoline additive recommended byGeneral Motors. It is available atyour dealer.
If your vehicle is able to use E85 orFlexFuel, GM Fuel SystemTreatment Cleaner - FlexFuel is theonly recommended additive for use.Do not use any other additives withan E85 or FlexFuel vehicle. SeeE85 or FlexFuel0312.
E85 or FlexFuel
Vehicles with a yellow sticker on thefuel door can use either unleadedgasoline or fuel containing up to85% ethanol (E85). All othervehicles should use only theunleaded gasoline as described inFuel0311.
The use of E85 or FlexFuel isencouraged when the vehicle isdesigned to use it. E85 or FlexFuelis made from renewable sources.
To h e l p l o c a t e f u e l s t a t i o n s t h a tcarry E85 or FlexFuel, the U.S.Department of Energy has analternative fuels website. Seewww.afdc.energy.gov/afdc/locator/stations.
E85 or FlexFuel should meetASTM Specification D 5798 orCAN/CGSB–3.512 in Canada. Do

Driving and Operating 313
not use the fuel if the ethanolcontent is greater than 85%. Fuelmixtures that do not meet ASTM orCGSB specifications can affectdriveability and could cause themalfunction indicator lamp tocome on.
For the 6.0L V8 engine, afterrefueling, the vehicle calculates thecomposition of the fuel. It is notrecommended to repeatedly switchbetween fuels. If fuels are switchedfrequently, add as much fuel aspossible and do not add less than11 L ( 3 g a l ) w h e n r e f u e l i n g . D r i v e a tleast 11 km (7 mi) immediately afterrefueling to allow the vehicle toadapt to the change in ethanolconcentration.
Because E85 or FlexFuel has lessenergy per liter (gallon) thangasoline, the vehicle will need to berefilled more often. SeeFilling theTa n k0313.
Caution
Some additives are not
compatible with E85 or FlexFuel
and can harm the vehicle's fuel
system. Do not add anything to
E85 or FlexFuel. Damage caused
by additives would not be covered
by the vehicle warranty.
Caution
Do not use fuel containing
methanol. It can corrode metal
parts in the fuel system and also
damage plastic and rubber parts.
That damage would not be
covered under the vehicle
warranty.
