Axle Fluid
Axles must have 2414 km (1500 mi)
before being used in track driving.
The 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. See your dealer
for the correct fluid.
Caution
During a first time track or racing

time the vehicle is driven on the
track or raced.
The axle lubricant should be
replaced with new lubricant.
On vehicles without a differential
cooler, additional cooling capacity is
required for continuous competitive
driving. The V-Series Blackwing has
a differential cooler, so no
additional cooling capacity is
necessary.
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 0 289.
Check the oil level often during track
events and competitive driving, and
keep the oil level at or near the upper
mark. See Checking the Engine Oil" in
Engine Oil 0 289.
Fuel
Use premium unleaded gasoline with
a posted octane rating of 98 RON at a
track event. Unleaded gasoline with a
posted octane rating of 95 RON may
be used, but performance will be
degraded.
Automatic Transmission Fluid
Have the transmission fluid set to the
track specific oil level prior to track
usage. Transmission fluid should be
changed after every 15 hours of track
usage. Any transmission level set or
change should be performed at your
dealer.
