This requires premium fuel, and
comes standard with a 10 L (10 qt)
sump, air/oil separator, integrated oil
cooler, and other powertrain and
powertrain cooling components in
preparation for track use.
Check the oil level often during track
events and competitive driving and
keep the oil level at or near the
upper mark.
Automatic Transmission Fluid
Have the gearbox fluid set to the track
specific oil level prior to track usage.
Gearbox fluid should be changed after
every 15 hours of track usage. Any
transmission level set or change
should be performed at your retailer.
Brake Fluid
Before racing, replace existing
brake fluid with a qualified racing
brake fluid from a sealed
container. Brake fluid with a dry
boiling point >279 °C (534 °F) is
qualified. If racing brake fluid is
used, replace it with GM approved
brake fluid before driving on
public roads. See Recommended
Fluids and Lubricants 0 322.
Do not use silicone-based fluids.
If racing 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 racing/closed track
driving.
Caution
Failure to change the brake fluid
and transfer case fluid after any
performance or race track driving
could result in damage not covered
by the vehicle warranty. Have the
brake fluid and transfer case fluid
changed by your dealer after any
performance or race track driving.
See Recommended Fluids and
Lubricants 0 322.
