248 Vehicle Care
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.
When selecting an oil of the appropriate
viscosity grade, it is recommended to select
an oil of the correct specification. See
“Specification” previously in this section.
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, 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 sewers, or into streams
or bodies of water. Recycle it by taking it to
a place that collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer that indicates
when to change the engine oil and filter.
This is based on a combination of factors
which include engine revolutions, engine
temperature, and miles driven. Based on
driving conditions, the mileage at which an
oil change is indicated can vary
considerably. For the oil life system to work
properly, the system must be reset every
time the oil is changed.
This vehicle has a racetrack-ready dry sump
engine lubrication system. This high
performance system operates differently
than a standard engine lubrication system
and requires a special procedure when
changing the engine oil and filter. See
Engine Oil (5.5L LT6 Engine)
0242 or
Engine Oil (6.2L LT2 Engine) 0245.
When the system has calculated that oil life
has been diminished, it indicates that an oil
change is necessary. A CHANGE ENGINE OIL
SOON message comes on. Change the oil as
soon as possible within the next 1 000 km
(600 mi). It is possible that, if driving under
the best conditions, the oil life system may
not indicate that an oil change is necessary
for up to a year. The engine oil and filter
must be changed at least once a year and,
at this time, the system must be reset. Your
dealer has trained service people who will
perform this work and reset the system.
It is also important to check the oil regularly
over the course of an oil drain interval and
keep it at the proper level.
If the system is ever reset accidentally, the
oil must be changed at 5 000 km (3,000 mi)
since the last oil change. Remember to reset
the oil life system whenever the oil is
changed.

Dual Clutch Transmission Fluid
How to Check Dual Clutch Transmission
Fluid
It is not necessary to check the transmission
fluid level. A transmission fluid leak is the
only reason for fluid loss. If a leak occurs,
take the vehicle to the dealer and have it
repaired as soon as possible. The vehicle is not equipped with a
transmission fluid level dipstick. There is a
special procedure for checking and changing
the transmission fluid. Because this
procedure is difficult, this should be done at
the dealer. Contact the dealer for additional
information or the procedure can be found
in the service manual. To purchase a service
manual, see
Publication Ordering
Information 0327.
Caution
Use of the incorrect transmission fluid
may damage the vehicle, and the
damage may not be covered by the
vehicle warranty. Always use the correct
transmission fluid. See Recommended
Fluids and Lubricants 0310.
Change the fluid and external canister filter
at the proper intervals. See Maintenance
Schedule 0306. Be sure to use the correct
