Engine Oil
Caution
If you use the vehicle for racing or
other competitive driving, the
engine may use more oil than it
would with normal use. Low oil
levels can damage the engine.
For information on how to add oil,
seeEngine Oil 0229.
Be sure to check the oil level
often during racing or other
competitive driving and keep the
level at or near the upper mark
that shows the proper operating
range on the engine oil dipstick. 3.6L (LGX) V6 Engine
Change the engine oil to 0W-40 or
5W-40 that meets the dexos2
specification. If this oil is not
available, the following oil can be
used as an alternative: Valvoline
SYNPOWER MST 5W-40.
For LS/LT 1LE, add 0.9 L (1.0 qt) of
oil over the nominal fill level for a
track event. After the competitive
driving, remove the excess oil so
that the level on the dipstick is not
above the upper mark that shows
the proper operating range.
During track usage, do not follow
the Engine Oil Life System status.
Change the engine oil after four
hours of accumulative track usage.
Fuel
Use premium unleaded gasoline
with a posted octane rating of 93 at
a track event. Unleaded gasoline
with a posted octane rating of
91 may be used, but performance
will be degraded.
Automatic Transmission Fluid
Have the transmission fluid set to
the track specific oil level prior to
track usage. Transmission fluid
should be changed after every
15 hours of track usage. Any
transmission level set or change
should be performed at your dealer.
Manual Transmission Fluid
Manual transmission fluid should be
changed after every 15 hours of
track usage.
Rear Axle Fluid
Axles must have 2 400 km
(1,500 mi) before being used in
track driving.
The rear axle fluid temperatures
may be higher than when driving in
severe conditions. Drain and refill
with new fluid after the first racing or
competitive driving event, and then
after every 24 hours of racing or
competitive driving. See
Recommended Fluids and
Lubricants
0315.

Fuel
Top Tier Fuel
GM recommends the use of TOP
TIER Detergent Gasoline to keep
the engine clean, reduce engine
deposits, and maintain optimal
vehicle performance. Look for the
TOP TIER Logo or see
www.toptiergas.com for a list of TOP
TIER Detergent Gasoline marketers
and applicable countries.
Recommended Fuel (3.6L
V6 Engine)
Use regular unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 87—
(R+M)/2 —or higher. Do not use
gasoline with a posted octane rating
of less than 87, as this may cause
engine knock and will lower fuel
economy.
Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
Recommended Fuel (2.0L
L4 Turbo Engine and 6.2L
V8 Engine)
Premium unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 93 —
(R+M)/2 —is highly recommended
for best performance and fuel
economy. Unleaded gasoline with
an octane rated as low as 87 can be
used. Using unleaded gasoline
rated below 93 octane, however, will
lead to reduced acceleration and
fuel economy. If knocking occurs,
use a gasoline rated at 93 octane
as soon as possible, otherwise, the
engine could be damaged. If heavy
knocking is heard when using
gasoline with a 93 octane rating, the
engine needs service.

214 Driving and Operating
Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
Recommended Fuel (6.2L
V8 Supercharged Engine)
Use premium unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 93—
(R+M)/2. If unavailable, unleaded
gasoline with a posted octane rating
of 91 may be used, but with reduced
performance and fuel economy.
If the octane is less than 91, the
engine could be damaged and the
repairs would not be covered by the
vehicle warranty. If heavy knocking
is heard when using gasoline rated
at 93 octane, the engine needs
service. Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so
may damage the vehicle and void
its warranty:
. For vehicles that are not
FlexFuel, fuel labeled
greater than 15% ethanol by
volume, such as mid-level
ethanol blends (16–50%
ethanol), E85, or FlexFuel.
. Fuel with any amount of
methanol, methylal,
ferrocene, and aniline.
These fuels can corrode
metal fuel system parts or
damage plastic and rubber
parts.
(Continued)
Caution (Continued)
.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.
Fuels in Foreign
Countries
The U.S., Canada, and Mexico post
fuel octane ratings in anti-knock
index (AKI). For fuel not to use in a
foreign country, see Prohibited
Fuels 0214.
