Fuel
If your vehicle has a diesel engine, seeDiesel
Engine Fuel on page 253.
For vehicles with gasoline engines, please
read this.
Use of the recommended fuel is an important part
of the proper maintenance of your vehicle. To
help keep your engine clean and maintain optimum
vehicle performance, GM recommends the use
of gasoline advertised as TOP TIER Detergent
Gasoline.
Gasoline Octane
Use regular unleaded gasoline with a posted
octane rating of 87 or higher. If the octane rating
is less than 87, you may notice an audible
knocking noise when you drive, commonly referred
to as spark knock. If this occurs, use a gasoline
rated at 87 octane or higher as soon as possible. If
you are using gasoline rated at 87 octane or
higher and you hear heavy knocking, your engine
needs service.
Gasoline Specications
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. SeeAdditives
on page 252for additional information.
251

Additives
To provide cleaner air, all gasolines in the United
States are now required to contain additives
that will help prevent engine and fuel system
deposits from forming, allowing your emission
control system to work properly. In most cases,
you should not have to add anything to your fuel.
However, some gasolines contain only the
minimum amount of additive required to meet U.S.
Environmental Protection Agency regulations.
To help keep fuel injectors and intake valves clean,
or if your vehicle experiences problems due to
dirty injectors or valves, look for gasoline that is
advertised as TOP TIER Detergent Gasoline. Also,
your dealer has additives that will help correct
and prevent most deposit-related problems.
Gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may
be available in your area. General Motors
recommends that you use these gasolines if they
comply with the specifications described earlier.
However, E85 (85% ethanol) and other fuels
containing more than 10% ethanol must not be
used in vehicles that were not designed for
those fuels.Notice:Your vehicle was not designed for
fuel that contains methanol. Do not use
fuel containing methanol. It can corrode metal
parts in your fuel system and also damage
the plastic and rubber parts. That damage
would not be covered under your warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing
additive called methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant where you
buy gasoline whether the fuel contains MMT.
General Motors recommends against the use of
such gasolines. Fuels containing MMT can reduce
the life of spark plugs and the performance of
the emission control system may be affected. The
malfunction indicator lamp may turn on. If this
occurs, return to your dealer for service.
252

Diesel Engine Fuel
For the Caterpillar®diesel, see the Caterpillar®
Operation & Maintenance Manual for information
concerning fuel usage.
Notice:Diesel fuel or fuel additives not
recommended in this manual could damage
your fuel system and engine. Your warranty
would not cover this damage. And:
Diesel fuel that has been mixed with engine
oil or automatic transmission uid could
damage your engine and emission controls.
Aftermarket diesel fuel additives are not
tested by General Motors. Some additives,
particularly those which contain alcohol or
water emulsiers, may damage your fuel
system. If you believe that unique
circumstances call for a fuel additive to be
used, consult your dealer for advice.
If you ever run out of diesel fuel, it can be
difficult to restart your engine. To avoid this,
never let your tank get empty.
If gasoline is ever accidentally added to the fuel
tank, to avoid severe engine damage, do not run
the engine until the fuel tank can be drained.
If you run out of fuel,Running Out of Fuel on
page 262tells you how to restart your engine.
What Fuel to Use
In the United States, for best results use
No. 2-D diesel fuel year-round (above and below
freezing conditions) as oil companies blend
No. 2-D fuel to address climate differences.
No. 1-D diesel fuel may be used in very cold
temperatures (when it stays below 0°F or−18°C);
however, it will produce a power and fuel
economy loss. Avoid the use of No. 1-D diesel
fuel in warm or hot climates. It may result in
stalling, poor starting when the engine is hot, and
may damage the fuel injection system.
It is important that diesel-powered trucks are
refueled only with ultra low-sulfur fuel. The
emission control system requires the use of diesel
fuel with ultra low-sulfur (0.0015% by weight, or
15 ppm, maximum) content. Both ultra low-sulfur
and higher sulfur diesel fuels are available in
the United States and ultra low-sulfur diesel fuel is
available in Canada. However, only higher
sulfur diesel fuel is available in Mexico. Use of
fuels with higher-sulfur content will affect the
function of the emission components and may
cause reduced performance, excessive smoke,
and unpleasant odor.
