184 Driving and Operating
after every 24 hours of racing or
competitive driving. See
Recommended Fluids and
Lubricants 0 328.
Caution
During a first time track or racing
event, high axle temperatures can
occur. Damage could be caused
to the axle and would not be
covered by the vehicle warranty.
Do not drive as long or as fast the
first time the vehicle is driven on
the track or raced.
Engine Oil
2.0L (LTG) Engine
This is not available with a track
package option and is not
recommended for track use.
6.2L Supercharged (LT4) Engine
Change the engine oil to 0W-40 or
5W-40 that meets the dexos2
specification. If this oil is not
available, the following oils can be
used as an alternative: Valvoline
SYNPOWER MST 5W-40, Mobil
ESP Formula M 5W-40. See
Capacities and Specifications 0 333.
This requires premium fuel, and
comes standard with a 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.
Brake Fluid
For track events and competitive
driving, it is recommended that the
brake fluid be replaced with a high
performance brake fluid that has a
dry boiling point greater than 279 °C
(534 °F). After conversion to the
high performance brake fluid, follow
the brake fluid service
recommendations outlined by the
fluid manufacturer. Do not use
silicone or DOT-5 brake fluids.

Caution
Removing the splash shield can
degrade wet braking
performance, as well as introduce
brake pedal pulsation, due to
brake disc exposure to road
debris. Only remove the front
brake disc splash shield and front
tyre deflector when driving in
track events.
Brake cooling can be improved if
the front brake disc splash shield
and front tyre deflector are removed.
Removing the shield will require that
the suspension bushings visible to
the brake disc be protected with
insulated thermal wrapping.
Brake Burnishing
To prepare the V-Sport and V-Series
brake systems for track events and
racing, complete the appropriate
high performance brake burnishing
procedure described below.
