182 DRIVING AND OPERATING
Axle Fluid
Axles must have 805 km (500 mi)
before being used in track driving.
The front, if equipped with AWD, and
rear axle fluid temperatures may be
higher than when driving in severe
conditions. Drain and refill with new
fluid after the first racing or
competitive driving event, and then
after every 24 hours of racing or
competitive driving. SeeRecommended
Fluids and Lubricants 0354.
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
Caution
If the vehicle is used for track
events and competitive driving, the
engine may use more oil than it
would with normal use. Low oil
levels can damage the engine.
Check the oil level often and
maintain the proper level. See
Engine Oil 0268.
2.0L (LTG) Engine
This is not available with a track
package option and is not
recommended for track use.
3.6L Non-Turbo (LGX) Engine
. With Oil Cooler: Confirm the oil
level is at the upper mark that
shows the proper operating range
on the engine oil dipstick.
. Without Oil Cooler: Do not use for
track events and competitive
driving. 3.6L Twin Turbo (LF3) Engine
The LF3 3.6L twin turbo engine comes
standard with a 7 qt sump, integrated
oil cooler, and other powertrain and
powertrain cooling components in
preparation for track use.
6.2L Supercharged (LT4) Engine
Keep the oil level at or near the upper
mark on the engine oil dipstick, which
shows the proper operating range.
Use 15W-50 full synthetic engine oil
for track use. After track use, change
the oil back to 0W-40 dexos2 for
street use. If 0W-40 dexos2 oil is not
available, 5W-30 dexos1 full synthetic
engine oil may be used for street use.
If 5W-30 dexos1 is used, it must be
changed to 15W-50 full synthetic
engine oil for track use. See
Capacities
and Specifications 0359.
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.

VEHICLE CARE 269
.If unable to wait two hours, the
engine must be off for at least
15 minutes if the engine is warm,
or at least 30 minutes if the
engine is not warm. Pull out the
dipstick, wipe it with a clean paper
towel or cloth, then push it back
in all the way. Remove it again,
keeping the tip down, and check
the level.
When to Add Engine Oil

3.6L V6 (LGX) Shown, 6.2L V8 (LT4)
Similar
If the oil is below the cross-hatched
area at the tip of the dipstick and the
engine has been off for at least
15 minutes, add 1 L (1 qt) of the
recommended oil and then recheck
the level. See “Selecting the Right
Engine Oil” later in this section for an
explanation of what kind of oil to use.
For engine oil crankcase capacity, see
Capacities and Specifications 0359.
Caution
Do not add too much oil. Oil levels
above or below the acceptable
operating range shown on the
dipstick are harmful to the engine.
If the oil level is above the
operating range (i.e., the engine has
(Continued)
Caution (Continued)
so much oil that the oil level gets
above the cross-hatched area that
shows the proper operating range),
the engine could be damaged. Drain
the excess oil or limit driving of the
vehicle, and seek a service
professional to remove the
excess oil.
See Engine Compartment Overview
0 261 for the location of the engine oil
fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when through.
Selecting the Right Engine Oil
(Except 6.2L (LT4) V8 Engine)
Selecting the right engine oil depends
on both the proper oil specification
and viscosity grade. See Recommended
Fluids and Lubricants 0354.
