.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.

Add enough oil to put the levelsomewhere in the proper operatingrange. Push the dipstick all the wayback in when through.
Selecting the Right Engine Oil
Selecting the right engine oildepends on both the proper oilspecification and viscosity grade.SeeRecommended Fluids andLubricants0462.
Specification
Ask for and use engine oils thatmeet the dexos1™specification.Engine oils that have beenapproved by GM as meeting thedexos1 specification are markedwith the dexos1 approved logo. Seewww.gmdexos.com.
Caution
Failure to use the recommended
engine oil or equivalent can result
in engine damage not covered by
the vehicle warranty.
Viscosity Grade
Use SAE 0W-20 viscosity grade forthe 5.3L and 6.2L V8 engines. UseSAE 5W-30 viscosity grade for the4.3L V6, and 6.0L V8 engines.
Cold Temperature Operation: In anarea of extreme cold, where thetemperature falls below✓29 °C(✓20 °F), an SAE 0W-30 oil may beused in the 4.3L or 6.0L engine. Anoil of this viscosity grade will provideeasier cold starting for the engine atextremely low temperatures.
When selecting an oil of theappropriate viscosity grade, it isrecommended to select an oil of thecorrect specification. See“Specification”earlier in this section.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. Therecommended oils meeting thedexos1 specification are all that isneeded for good performance andengine protection.
Engine oil system flushes are notrecommended and could causeengine damage not covered by thevehicle warranty.

Warning (Continued)
overheat warning. The engine
could catch fire and you or others
could be burned. Use a
50/50 mixture of clean, drinkable
water and DEX-COOL coolant.
Use a 50/50 mixture of clean,drinkable water and DEX-COOLcoolant. If using this mixture,nothing else needs to be added.This mixture:
.Gives freezing protection downto✓37 °C (✓34 °F), outsidetemperature.
.Gives boiling protection up to129 °C (265 °F), enginetemperature.
.Protects against rust andcorrosion.
.Will not damage aluminum parts.
.Helps keep the proper enginetemperature.
Caution
If improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much water in the
mixture can freeze and crack
engine cooling parts. The repairs
would not be covered by the
vehicle warranty. Use only the
proper mixture of engine coolant
for the cooling system. See
Recommended Fluids and
Lubricants0462.
Never dispose of engine coolant byputting it in the trash, or by pouringit on the ground, or into sewers,streams, or bodies of water. Havethe coolant changed by anauthorized service center, familiarwith legal requirements regardingused coolant disposal. This will helpprotect the environment and yourhealth.
