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, see
Engine Oil0235.
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.
6.2L (LT1) V8 Engine
The LT1 engine is factory filled with 0W-40
dexosR oil. 0W-40 dexosR engine oil is
approved for both track and street use with
the LT1 engine. 15W-50 full synthetic engine
oil may also be used for track use, but after
track use must be changed back to 0W-40
dexosR for street use. See
Capacities and
Specifications 0309.
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 checked and set
to proper 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.
Brake Fluid
Replace existing brake fluid with a qualified
high performance DOT 4 brake fluid from a
sealed container. Brake fluid with a dry
boiling point >310 °C (590 °F) is qualified.
If high performance brake fluid is used,
replace it with GM approved brake fluid
before driving on public roads. If high
performance brake fluid is in the vehicle and
the age of the brake fluid is over a month
old or unknown, replace the brake fluid
before track events and competitive driving.
Do not use silicone or DOT 5 brake fluids.
Check the fluid level before each competitive
driving event.

Recommended Fuel (3.6L
V6 Engine)
Regular unleaded gasoline meeting ASTM
specification D4814 with a posted octane
rating (R+M)/2 of 87 or greater is
recommended. Do not use gasoline with a
posted octane rating of less than 87, as this
will result in reduced performance and
driveability. If heavy knocking is heard when
using gasoline rated at 87 or greater, 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.
Recommended Fuel (2.0L L4 Turbo
Engine and 6.2L V8 Engine)
Premium unleaded gasoline meeting ASTM
specification D4814 with a posted octane
rating (R+M)/2 of 91 or greater is
recommended. If unavailable, unleaded
gasoline with a posted octane rating of
87 may be used, but will result in reduced
performance and driveability. If heavy
knocking is heard when using gasoline rated
at 91 or greater, 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.
Recommended Fuel (6.2L V8
Supercharged Engine)
Premium unleaded gasoline meeting ASTM
specification D4814 with a posted octane
rating (R+M)/2 of 91 or greater is required.
The use of the correct fuel is an important
part of the proper maintenance of the
vehicle and a condition of the vehicle
warranty. If heavy knocking is heard when
using gasoline rated at 91 or greater, 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.
.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 Fuels0224.
Fuel Additives
TOP TIER Detergent Gasoline is highly
recommended for use with your vehicle.
If your country does not have TOP TIER
Detergent Gasoline, add ACDelco Fuel
System Treatment Plus−Gasoline to the
vehicle’s gasoline fuel tank at every oil
change or 15 000 km (9,000 mi), whichever
occurs first. TOP TIER Detergent Gasoline and
ACDelco Fuel System Treatment Plus
−Gasoline will help keep your vehicle’s
engine fuel deposit free and performing
optimally.
Filling the Tank
An arrow on the fuel gauge indicates which
side of the vehicle the fuel door is on. See
Fuel Gauge 088.
{Warning
Fuel vapors and fuel fires burn violently
and can cause injury or death.
Follow these guidelines to help avoid
injuries to you and others:
.Read and follow all the instructions on
the fuel pump island.
.Turn off the engine when refueling.
.Keep sparks, flames, and smoking
materials away from fuel.
.Do not leave the fuel pump
unattended.
.Avoid using electronic devices while
refueling.
.Do not re-enter the vehicle while
pumping fuel.
.Keep children away from the fuel
pump and never let children
pump fuel.
