If this occurs, return to your
authorized dealer for diagnosis. If it
is determined that the condition is
caused by the type of fuel used,
repairs may not be covered by the
vehicle warranty.
Fuels in Foreign
Countries
If planning to drive in countries
outside the U.S. or Canada, the
proper fuel might be hard to find.
Check regional auto club or fuel
retail brand websites for availability
in the country where driving. Never
use leaded gasoline, fuel containing
methanol, manganese, or any other
fuel not recommended. Costly
repairs caused by use of improper
fuel would not be covered by the
vehicle warranty.
Fuel Additives
To keep fuel systems clean, TOP
TIER Detergent Gasoline is
recommended. See Fuel0206.
If TOP TIER Detergent Gasoline is
not available, one bottle of Fuel
System Treatment PLUS added to
the fuel tank at every engine oil
change, can help. Fuel System
Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.

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.

224 Vehicle Care
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
2. Pull the dipstick and 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
(Except Stingray with
Z51 and Z06)
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
and then recheck the level. See
“Selecting the Right Engine Oil” inthis section for an explanation of
what kind of oil to use. For engine
oil crankcase capacity, see
Capacities and Specifications
0312.
See Track Events and Competitive
Driving 0162 for additional
information on engine oil.
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 you find that you
have an oil level 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. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil. See
Engine Compartment Overview
0 218 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.

The engine oil dipstick handle is a
loop. The dipstick is located on the
dry sump engine oil tank. See
Engine Compartment Overview
0218 for the location of the dry
sump engine oil tank.
These vehicles 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 checking
the engine oil level. Follow this
procedure closely.
The engine oil level must be
checked when the engine is warm.
Cold oil level in the dry sump tank
may not indicate the actual amount
of oil in the system. With this
system, engine oil is contained in an
external tank, separate from the
engine. Under normal operating
conditions, the oil pan under the
engine does not store any oil. If the
vehicle has been parked for an
extended period without the engine
being started, some oil will seep
back into the oil pan, reducing the
amount of oil held in the dry sump tank and there could be no engine
oil at all showing on the dipstick.
This is normal since the dipstick is
designed to read the engine oil level
only after the engine has run long
enough to reach normal operating
temperature. Do not add engine oil
based on cold engine dipstick
readings. The engine oil level on the
dipstick will also be inaccurate if
checked while the engine is running.
1. To obtain an accurate engine oil level reading, warm up the
engine to at least 80 °C
(175 °F). Cold oil will not give a
correct oil level reading.
2. Once the engine is warm, turn off the engine. Checking the oil
while the engine is running will
result in an incorrect oil level
reading.
3. Check the oil level between five and 10 minutes after the
engine is shut down.{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
4. Remove the dipstick from the external engine oil tank and
wipe it with a clean lint-free
paper towel or a cloth.
Re-insert the dipstick into the
external oil tank, pushing it all
the way in until it stops.
5. Remove the dipstick from the oil tank and read the level on
the cross-hatched area.

226 Vehicle Care
When to Add Engine Oil
(Stingray with Z51 and Z06)
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
through the oil fill cap opening in the
oil tank and then recheck the level.
See“Selecting the Right Engine Oil”
for an explanation of what kind of oil
to use. For engine oil crankcase
capacity, see Capacities and
Specifications 0312.
See Track Events and Competitive
Driving 0162 for additional
information on engine oil.
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 you find that you
have an oil level 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. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
See Engine Compartment Overview
0 218 for the location of the external
engine oil tank and fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back into the oil tank when through.
Changing Engine Oil and Filter
(Stingray with Z51 and Z06)
The vehicle may 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. Follow this
procedure closely when changing
the engine oil and filter.
1. Engine Oil Drain Plugs

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
