simple, but important steps will
help protect your investment:
.Always use engine oil approved
to the proper specification and
of the proper viscosity grade.
See “Selecting the Right
Engine Oil.”
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil.”
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10‑22.
.Always dispose of engine oil
properly. See “What to Do With
Used Oil.”

Checking Engine Oil (Except
ZO6, ZR1, and Grand Sport)
If the CHECK OIL LEVEL message
displays on the Driver Information
Center (DIC), check the engine
oil level right away. For more
information, seeEngine Oil
Messages on page 5‑40. Check
the engine oil level regularly;
this is an added reminder.
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 yellow loop. See Engine
Compartment Overview on
page 10‑10 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
allow several minutes for the oil
to drain back into the oil pan.
Checking your oil level too soon
after engine shut off will not
provide an accurate oil level
reading.
2. Pull the dipstick and clean it with a 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 ZO6, ZR1, and Grand
Sport)
If the oil is below the cross-hatched
area at the tip of the dipstick, add
one liter/quart of the recommended
oil 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 on page 12‑2.

SeeRacing or Other Competitive
Driving on page 9‑7 for additional
information on engine oil.
Notice: 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 your
driving of the vehicle and seek a
service professional to remove
the excess amount of oil.
See Engine Compartment Overview
on page 10‑10 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.Checking Engine Oil (ZO6,

A. Engine Oil Dipstick
B. Engine Oil Fill Cap
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
yellow loop. The dipstick is located
on the dry sump engine oil tank.
See Engine Compartment Overview
on page 10‑10 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 when
checking the engine oil level.
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.

10-18 Vehicle Care
This is normal since the dipstick is
designed to read 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 engineoil 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. Wait at least five minutes (but not more than 20 minutes)
to allow oil to drain and settle in
the engine. 4. Remove the dipstick from the
external engine oil tank and
clean it with a 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. Oil levels
that fall in the cross‐hatched
area are normal.
When to Add Engine Oil
(ZO6, ZR1, and Grand Sport)
If the oil is below the cross-hatched
area at the tip of the dipstick, add
one liter/quart 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 on
page 12‑2.
See Racing or Other Competitive
Driving on page 9‑7 for additional
information on engine oil.
Notice: Do not add too much oil.
Oil levels above or below the

A. Engine Oil Drain Plugs
B. Seals
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. Re‐install both drain plugs and tighten them to 2 Y(18 lb ft).
4. Replace the oil filter and tighten it to 30 Y(22 lb ft).
See Maintenance Replacement
Parts on page 11‑8 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 9.9 L (10.5 quarts) of oil to the oil tank. See Capacities and
Specifications on page 12‑2.
7. Install the oil fill cap and insert the dipstick, if removed.

8. Start the engine and let it runat 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 (ZO6,
ZR1, and Grand Sport).”
Selecting the Right Engine Oil
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade:
Specification
Use and ask for engine oils with
the dexos™ certification mark.
Oils meeting the requirements
of your vehicle should have the
dexos™ certification mark on the
container. This certification mark
indicates that the oil has been
approved to the dexos™
specification.
Your vehicle was filled at the factory
with dexos™ approved engine oil.
Notice: Use only engine oil
that is approved to the dexos™
specification or an equivalent
engine oil of the appropriate
viscosity grade. Engine oils
approved to the dexos™
specification will show the
dexos™ symbol on the container.
Failure to use the recommended
engine oil or equivalent can result
in engine damage not covered
by the vehicle warranty. If you
are unsure whether your oil
is approved to the dexos™
specification, ask your service
provider. It is recommended to use
Mobil 1
®engine oils that meet
the requirements of the dexos™
specification.
Use of Substitute Engine Oils if
dexos™ is unavailable: In the
event that dexos™ approved engine
oil is not available at an oil change
or for maintaining proper oil level,
you may use substitute engine oil
displaying the API Starburst symbol
and of SAE 5W-30 viscosity grade.
Use of oils that do not meet the
dexos™ specification, however,
may result in reduced performance
under certain circumstances.
Viscosity Grade
SAE 5W-30 is the best viscosity
grade for the vehicle. Do not
use other viscosity oils such as
SAE 10W‐30, 10W‐40, or 20W-50.

Black plate (21,1)Chevrolet Corvette Owner Manual - 2011
Vehicle Care 10-21
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below−29°C
(−20°F), an SAE 0W-30 oil should
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, be sure to always select
an oil that meets the required
specification, dexos™. See
“Specification” for more information.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil.
The recommended oils with the
dexos™specification and displaying
the dexos™ certification mark
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 engine revolutions and engine
temperature, and not on mileage.
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.
Z06, ZR1, and Grand Sport 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. SeeEngine
Oil on page 10‑15. When the system has calculated
that oil life has been diminished,
it indicates that an oil change is
necessary. A CHANGE ENGINE
OIL message comes on. Change
the oil as soon as possible within
the next 1 000 km (600 miles). It is
possible that, if driving under the
best conditions, the oil life system
might indicate that an oil change
is not 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 miles)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Press the TRIP button so
the OIL LIFE percentage is
displayed.
2. Press RESET and hold for two seconds. OIL LIFE
REMAINING 100% will appear.
If the CHANGE ENGINE OIL
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.
