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 0228.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil (Except
Stingray with Z51 and Z06)
If the ENGINE OIL LOW–ADD OIL
message displays on the Driver
Information Center (DIC), check the
engine oil level right away. See
Engine Oil Messages 0123. Check
the engine oil level regularly.
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
See Engine Compartment Overview
0 218 for the location of the engine
oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running recently, turn off the engine and
check within five and
10 minutes of shutoff.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.

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
