Racing or Other Competitive Driving
Racing or competitive driving may affect the vehicle
warranty. See the warranty book before using the
vehicle for racing or other competitive driving.
Notice: 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 Oil on page 5-19.
Z06 and ZR1 Only: 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.
Except Z06 and ZR1: Be sure to check the oil level
often during racing or other competitive driving and
keep the level at or near 1 quart (1 L) above 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.
Z06 and ZR1 Only: For racing or 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 534°F (279°C). 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.
If the vehicle is a ZO6 or ZR1 model or has the Z51
performance package, it has greaseable outer ends on
both of the rear toe-links. Under normal use, lubrication
should be performed as described in the maintenance
schedule. See Scheduled Maintenance on page 6-4
and Recommended Fluids and Lubricants on page 6-12.
If using the vehicle for racing, lubrication should be
performed at the end of each racing day. See your
dealer/retailer for lubrication and make sure any needed
repairs are made at once. Proper procedures for
performing these services can be found in the service
manual. See Service Publications Ordering Information
on page 7-16.
If the vehicle is used for racing or other competitive
driving, the rear axle fluid temperatures may be higher
than would occur in normal driving. We recommend
that the rear axle fluid be drained and refilled with new
fluid after every 24 hours of racing or competitive
driving. See Recommended Fluids and Lubricants on
page 6-12 for what fluid to use.
