Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583589) - 2021 - CRC - 10/1/20
186 Driving and Operating
3.6L (LGX) V6 Engine
Change the engine oil to 0W-40 or 5W-40
that meets the dexos2 specification. If this
oil is not available, the following oil can be
used as an alternative: Valvoline SYNPOWER
MST 5W-40.
For LS/LT 1LE, add 0.9 L (1.0 qt) of oil over
the nominal fill level for a track event. After
the competitive driving, remove the excess
oil so that the level on the dipstick is not
above the upper mark that shows the
proper operating range.
During track usage, do not follow the Engine
Oil Life System status. Change the engine oil
after four hours of accumulative track usage.
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.
Automatic Transmission Fluid
Have the transmission fluid set to the track
specific oil level prior to track usage.
Transmission fluid should be changed afterevery 15 hours of track usage. Any
transmission level set or change should be
performed at your dealer.
Manual Transmission Fluid
Manual transmission fluid should be
changed after every 15 hours of track usage.
Rear Axle Fluid
Axles must have 2 400 km (1,500 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
Recommended Fluids and Lubricants
0313.
Caution
During a first time track or racing event,
high rear axle temperatures can occur.
Damage could be caused to the rear 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 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
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.
Brake Burnishing
To prepare the Camaro brake systems for
track events and racing, complete the
appropriate high performance brake
burnishing procedure described below.
New brake pads must be burnished before
racing or competitive driving.
Caution
These procedures are specific to the
Camaro LT with Y4Q Heavy Duty Cooling
System and J55 brakes, SS, ZL1, and
models equipped with the 1LE track
package. This procedure should not be
run on other Camaro models equipped

LCA can be disabled through vehicle
personalization. See“Collision/Detection
Systems” underVehicle Personalization
0 104. If LCA is disabled by the driver, the
LCA mirror displays will not light up.
When the System Does Not Seem to
Work Properly
The LCA system requires some driving for
the system to calibrate to maximum
performance. This calibration may occur
more quickly if the vehicle is driving on a
straight highway road with traffic and
roadside objects (e.g., guardrails, barriers).
LCA displays may not come on when
passing a vehicle quickly or for a stopped
vehicle. LCA may alert to objects attached to
the vehicle, such as a bicycle or object
extending out to either side of the vehicle.
Attached objects may also interfere with the
detection of vehicles. This is normal system
operation; the vehicle does not need service.
LCA may not always alert the driver to
vehicles in the next lane over, especially in
wet conditions or when driving on sharp
curves. The system does not need to be
serviced. The system may light up due to guardrails, signs, trees, shrubs, and other
non-moving objects. This is normal system
operation; the vehicle does not need service.
LCA may not operate when the LCA sensors
in the left or right corners of the rear
bumper are covered with mud, dirt, snow,
ice, or slush, or in heavy rainstorms. For
cleaning instructions, see "Washing the
Vehicle" under
Exterior Care0294. If the
DIC still displays the system unavailable
message after cleaning both sides of the
vehicle toward the rear corners of the
vehicle, see your dealer.
If the LCA displays do not light up when
moving vehicles are in the side blind zone or
rapidly approaching this zone and the
system is clean, the system may need
service. Take the vehicle to your dealer.

Fuel
Top Tier Fuel
GM recommends the use of TOP TIER
Detergent Gasoline to keep the engine clean,
reduce engine deposits, and maintain
optimal vehicle performance. Look for the TOP TIER Logo or see www.toptiergas.com
for a list of TOP TIER Detergent Gasoline
marketers and applicable countries.
Recommended Fuel (3.6L
V6 Engine)
Use regular unleaded gasoline meeting
ASTM specification D4814 with a posted
octane rating of 87
—(R+M)/2 —or higher.

Chevrolet Camaro Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14583589) - 2021 - CRC - 10/1/20
230 Driving and Operating
Do not use gasoline with a posted octane
rating of less than 87, as this may cause
engine knock and will lower fuel economy.
Do not use any fuel labeled E85 or FlexFuel.
Do not use gasoline with ethanol levels
greater than 15% by volume.
Recommended Fuel (2.0L L4 Turbo
Engine and 6.2L V8 Engine)
Premium unleaded gasoline meeting ASTM
specification D4814 with a posted octane
rating of 93—(R+M)/2 —is highly
recommended for best performance and fuel
economy. Unleaded gasoline with an octane
rated as low as 87 can be used. Using
unleaded gasoline rated below 93 octane,
however, will lead to reduced acceleration
and fuel economy. If knocking occurs, use a
gasoline rated at 93 octane as soon as
possible, otherwise, the engine could be
damaged. If heavy knocking is heard when
using gasoline with a 93 octane rating, the
engine needs service. Do not use any fuel labeled E85 or FlexFuel.
Do not use gasoline with ethanol levels
greater than 15% by volume.
Recommended Fuel (6.2L V8
Supercharged Engine)
Use premium unleaded gasoline meeting
ASTM specification D4814 with a posted
octane rating of 93
—(R+M)/2.
If unavailable, unleaded gasoline with a
posted octane rating of 91 may be used, but
with reduced performance and fuel
economy. If the octane is less than 91, the
engine could be damaged and the repairs
would not be covered by the vehicle
warranty. If heavy knocking is heard when
using gasoline rated at 93 octane, the
engine needs service.
Do not use any fuel labeled E85 or FlexFuel.
Do not use gasoline with ethanol levels
greater than 15% by volume.
Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:
.For vehicles that are not FlexFuel, fuel
labeled greater than 15% ethanol by
volume, such as mid-level ethanol
blends (16–50% ethanol), E85,
or FlexFuel.
.Fuel with any amount of methanol,
methylal, ferrocene, and aniline. These
fuels can corrode metal fuel system
parts or damage plastic and rubber
parts.
.Fuel containing metals such as
methylcyclopentadienyl manganese
tricarbonyl (MMT), which can damage
the emissions control system and
spark plugs.
.Fuel with a posted octane rating of
less than the recommended fuel. Using
this fuel will lower fuel economy and
performance, and may decrease the
life of the emissions catalyst.
