24 Driving and Operating
Competitive Driving Mode, PTM, and Launch
Control are systems designed for a closed
course race track and not intended for use
on public roads. The systems are not
intended to compensate for lack of driver
experience or familiarity with the race track.
Custom Launch Control may be available
through the Settings menu, if equipped. See
“Custom Launch Control”in Track Events and
Competitive Driving in the owner’s manual.
Limited-Slip Differential
The Electronic Limited-Slip Differential (eLSD)
is a hydraulically actuated clutch system.
It can infinitely vary the clutch engagement
between 0 and 2000 Y(1475 lb ft) of
breakaway torque between the rear wheels.
It responds to full engagement within
0.150 seconds when necessary. Smaller
clutch adjustments happen even faster.
The eLSD:
.Uses the vehicle sensors and driver inputs
to determine the optimum amount of
clutch engagement for the conditions.
.Improves traction while cornering by
changing the engagement to achieve a
balance between directional control and
acceleration.
.Provides optimal engagement for
high-speed control and stability without
affecting precise steering and turn-in.
.Improves vehicle stability during spirited
driving and evasive maneuvers. Is fully
integrated with the Active Handling and
Performance Traction Management (PTM)
systems.
There are unique calibrations based on the
Traction Control System (TCS) setting. eLSD
modes change automatically when
Yis
pressed. No unique input from the driver is
required.
.Mode 1 is the standard mode when the
vehicle is started. It provides a touring
calibration with an emphasis on vehicle
stability. Mode 1 is also used in PTM
Wet mode.
.Mode 2 is engaged when both TCS and
StabiliTrak/Electronic Stability Control
(ESC) are turned off. This calibration
provides more nimble corner turn-in, and
is biased for better traction out of
corners.
.Mode 3 is engaged when PTM is engaged
in Dry, Sport 1 & 2, and Race modes. This
is a nimble calibration with similar
functionality as eLSD Mode 2, however, it
is integrated to work with PTM.
.Mode 4 is engaged when TCS is selected
off, but StabiliTrak/ESC remains on.
Vehicle stability is still the priority, while
allowing for optimized traction out of
corners.
The ZL1 1LE, ZL1 coupe, and SS 1LE are
calibrated uniquely and optimized for their
unique powertrain and chassis combinations.

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.
(Continued)
Caution (Continued)
.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

Engine Oil
To ensure proper engine performance and
long life, careful attention must be paid to
engine oil. Following these simple, but
important steps will help protect your
investment:
.Use engine oil approved to the proper
specification and of the proper viscosity
grade. See “Selecting the Right Engine
Oil” in this section.
.Check the engine oil level regularly and
maintain the proper oil level. See
“Checking Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the appropriate
time. See“Engine Oil Life System” in the
owner’s manual.
.Always dispose of engine oil properly. See
“What to Do with Used Oil” in this
section.
Checking Engine Oil
Check the engine oil level regularly, every
650 km (400 mi), especially prior to a long
trip. The engine oil dipstick handle is a loop.
See Engine Compartment Overview 027 for
the location.
{Warning
The engine oil dipstick handle may be
hot; it could burn you. Use a towel or
glove to touch the dipstick handle.
If a low oil Driver Information Center (DIC)
message displays, check the oil level.
Follow these guidelines:
.To get an accurate reading, park the
vehicle on level ground. Check the engine
oil level after the engine has been off for
at least two hours. Checking the engine
oil level on steep grades or too soon after
engine shutoff can result in incorrect readings. Accuracy improves when
checking a cold engine prior to starting.
Remove the dipstick and check the level.
.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
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 043.

Vehicle Care 29
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 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 027 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
Selecting the right engine oil depends on
both the proper oil specification and
viscosity grade. See Recommended Fluids
and Lubricants 041. Specification
Use engine oils that meet the dexos2
specification. Engine oils that have been
approved by GM as meeting the dexos2
specification are marked with the dexos2
approved logo. See www.gmdexos.com.
Caution
Failure to use the recommended engine
oil or equivalent can result in engine
damage not covered by the vehicle
warranty.
Viscosity Grade
Use SAE 0W-40 viscosity grade engine oil for
the LT1 and LT4 engines.
When selecting an oil of the appropriate
viscosity grade, it is recommended to select
an oil of the correct specification. See
“Specification” earlier in this section. If 0W-40 dexos2 oil is not available, SAE
5W-30 dexos1 full synthetic engine oil may
be used for street use.
Engine Oil Additives/Engine Oil Flushes
Do not add anything to the oil. The
recommended oils meeting the dexos
specification are all that is needed for good
performance and engine protection.
Engine oil system flushes are not
recommended and could cause engine
damage not covered by the vehicle
warranty.
What to Do with Used Oil
Used engine oil contains certain elements
that can be unhealthy for your skin and
could even cause cancer. Do not let used oil
stay on your skin for very long. Clean your
skin and nails with soap and water, or a
good hand cleaner. Wash or properly
dispose of clothing or rags containing used
engine oil. See the manufacturer's warnings
about the use and disposal of oil products.
Used oil can be a threat to the environment.
If you change your own oil, be sure to drain
all the oil from the filter before disposal.
Never dispose of oil by putting it in the
trash or pouring it on the ground, into

Chevrolet Camaro High Performance Owner Manual Supplement (GMNA-
Localizing-U.S./Canada/Mexico-14584225) - 2021 - CRC - 9/30/20
30 Vehicle Care
sewers, or into streams or bodies of water.
Recycle it by taking it to a place that
collects used oil.
Engine Air Filter Life System

Brakes
Due to California and Washington law, brake
service for some high-performance Camaros
manufactured after December 31, 2020,
cannot be conducted using GM original
equipment brake pads in those states.
Service requiring original equipment brake
pads can be performed at any GM
dealership in the remaining 48 states.
Otherwise, replacement of brake pads in
California or Washington will require
replacement of additional brake system
components. See your dealer to verify the
manufacture date for your vehicle.
Wheels and Tires
Low-Profile Tires
If the vehicle has 285/30ZR20,
305/30ZR20, 305/30ZR19, or 325/30ZR19
size tires, they are classified as
low-profile tires. Caution
Low-profile tires are more susceptible to
damage from road hazards or curb impact
than standard profile tires. Tire and/or
wheel assembly damage can occur when
coming into contact with road hazards
like potholes, or sharp edged objects,
or when sliding into a curb. The warranty
does not cover this type of damage. Keep
tires set to the correct inflation pressure
and when possible, avoid contact with
curbs, potholes, and other road hazards.
Competition Oriented Tires
This vehicle may come with 305/30ZR19 and
325/30ZR19 Goodyear Eagle F1 Supercar 3R
competition oriented tires that are DOT
approved for street use. Competition
oriented tires use a special tread pattern
and compound that provide more grip than
normal road tires. The minimum tread depth
will be reached earlier than typical tires,
resulting in reduced tire life. This special
tread pattern and compound will have
decreased performance in cold climates,
heavy rain, and standing water. It is
recommended that winter tires be installed
