Track Events And Competitive - Cadillac CTS-V 2019 Owner's Manual

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 6.6 L (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 0 333.
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.
For the LT4 6.2L supercharged engine,
consider using unleaded fuel with an
octane rating greater than 100 RON if
the air temperature is above 30 °C
(86 °F). Do not use any fuel with
conditions listed in Prohibited Fuels
0 236.
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.
Axle Fluid
Axles must have 805 km (500 mi)
before being used in track driving.
DRIVING AND OPERATING
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. 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.
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
