Engine OilCaution
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 Oil028.
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. The LT1 and LT4 engines are factory filled
with 0W-40 dexos2 oil. 0W-40 dexos2
engine oil is approved for both track and
street use with the LT1 and LT4 (ZL1 only,
not ZL1 1LE) engines. 15W-50 full synthetic
engine oil may also be used for track use
and is required on the ZL1 1LE, but after
track use must be changed back to 0W-40
dexos2 for street use. See
Capacities and
Specifications 043.
Fuel
Consider using 100 octane unleaded gasoline
if the air temperature is above 30 °C (86 °F)
at a track event. Do not use any fuel with
conditions listed in Prohibited Fuels025.
Automatic Transmission Fluid
Transmission fluid should be changed after
every 15 hours of track use. 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.
Tire Pressures
Tire pressure specifications are listed
in psi (kPa). Limit the vehicle weight to a
maximum of the driver and one passenger,
with no additional cargo.

Recommended Fuel
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.
