Vehicle Care 227
Steps to follow:1. Remove the two engine oil drain plugs from the bottom of
the engine oil pan. One drain
plug drains the external oil tank
via the oil transfer supply line.
The other drain plug drains
residual oil from the crankcase
sump. Allow the oil to drain.
2. Once the oil has been drained from the engine, remove the
engine oil filter and allow the oil
to drain.
3. Reinstall both drain plugs and tighten them to 25 Y
(18 lb ft).
4. Replace the oil filter and tighten it three-quarters to one
turn after gasket contact. See
Maintenance Replacement
Parts 0309 for the correct filter.
5. Oil is filled through the opening in the top of the external
engine oil tank. Remove the oil
fill cap.
6. Add oil to the oil tank. See Capacities and
Specifications 0312. 7. Install the oil fill cap and insert
the dipstick, if removed.
8. Start the engine and let it run at idle for at least 15 seconds.
This will circulate the fresh
engine oil through the
lubrication system.
9. Shut off the engine and check the oil level as described under
“Checking Engine Oil
(Z51 and Z06).”
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 0307.
Specification
Ask for and use engine oils that
meet the dexos1™ specification.
Engine oils that have been
approved by GM as meeting the
dexos1 specification are marked
with the dexos1 approved logo. See
www.gmdexos.com.
GM recommends Mobil 1
®engine
oils that show the dexos1 approved
logo for its dry sump equipped
engines.
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 5W-30 viscosity grade
engine oil.
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below −29 °C
(−20 °F), an SAE 0W-30 oil may be
used. An oil of this viscosity grade
will provide easier cold starting for
the engine at extremely low
temperatures. 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.
For track events or competitive
driving, use Mobil 1
®15W-50 engine
oil. An instrument cluster warning
light will be illuminated at high oil
temperatures. See Driver
Information Center (DIC) 0113.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils meeting the
dexos1™ 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 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.Z51 and Z06 models have 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 0223.
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.
