Gasoline Octane

If your vehicle has the 6.0L V8 engine (VIN Code U),

use premium unleaded gasoline with a posted octane

rating of 91 or higher. You may also use regular

unleaded gasoline rated at 87 octane or higher, but

your vehicle’s acceleration may be slightly reduced,

and you may notice a slight audible knocking noise,

commonly referred to as spark knock. If the octane is

less than 87, you may notice a heavy knocking

noise when you drive. If this occurs, use a gasoline

rated at 87 octane or higher as soon as possible.

Otherwise, you might damage your engine. If you are

using gasoline rated at 87 octane or higher and you hear

heavy knocking, your engine needs service.

If your vehicle has the 7.0L V8 engine (VIN Code E),

use premium unleaded gasoline with a posted octane

rating of 91 or higher. For best performance, use

premium unleaded gasoline with a posted octane

rating of 93. In an emergency, you can use regular

unleaded gasoline with an octane rating of 87 or

higher. If 87 octane fuel is used, do not perform any

aggressive driving maneuvers such as wide open throttle

applications. You may also hear audible spark knock

during acceleration. Reﬁll your tank with premium fuel

as soon as possible to avoid damaging your engine.

If you are using gasoline rated at 91 octane or

higher and you hear heavy knocking, your engine

needs service.

Gasoline Speciﬁcations

At a minimum, gasoline should meet ASTM

speciﬁcation D 4814 in the United States or

CAN/CGSB-3.5 in Canada. Some gasolines may

contain an octane-enhancing additive called

methylcyclopentadienyl manganese tricarbonyl (MMT).

General Motors recommends against the use of

gasolines containing MMT. See Additives on page 5-6

for additional information.

California Fuel

If your vehicle is certiﬁed to meet California Emissions

Standards, it is designed to operate on fuels that

meet California speciﬁcations. See the underhood

emission control label. If this fuel is not available

in states adopting California emissions standards,

your vehicle will operate satisfactorily on fuels meeting

federal speciﬁcations, but emission control system

performance may be affected. The malfunction

indicator lamp may turn on and your vehicle may fail a

smog-check test. See Malfunction Indicator Lamp

on page 3-42. If this occurs, return to your authorized

GM dealer for diagnosis. If it is determined that the

condition is caused by the type of fuel used, repairs may

not be covered by your warranty.
