Package: Additional oil fill above the
upper mark on the dipstick is not
recommended for track events or
other competitive driving. 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. After the
competitive driving, remove excess
oil so that the level on the dipstick is
not above the upper mark that
shows the proper operating range.
Fuel
LT1 Engine :93 octane (or higher)
unleaded gasoline is required.
LT4 Engine : 93 octane (or higher)
unleaded gasoline is required.
100 octane (or higher) unleaded
gasoline is recommended at the
track when temperatures are above
30 °C (86 °F) to maximize
powertrain performance and
improve longevity of components
within the powertrain. LT5 Engine :
93 octane (or higher)
unleaded gasoline is required.
100 octane (or higher) unleaded
gasoline is recommended to
maximize powertrain performance
and improve longevity of
components within the powertrain.
Caution
Some high octane fuels contain
additives and compounds that
may damage the vehicle and void
the vehicle warranty. See
Prohibited Fuels 0213.
Automatic Transmission Fluid
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.

Recommended Fuel
(LT4 and LT5 6.2L
Supercharged
V8 Engines)
Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
Use premium unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 93.
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.
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
(Continued)
Caution (Continued)
(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 0213.
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
