As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle. However, you can use
SAE
1OW-30 if it’s going to be 0°F (-18°C) or above.’
These numbers on an oil container show its viscosity,
or thickness.
Do not use other viscosity oils such as
SAE
2OW-50.
Oils meeting these
requirements should also
have the “Starburst” symbol on the container.
This symbol indicates that the oil has been certified by
the American Petroleum Institute (API).
Do not use any
oil which does not
carry this Starburst symbol.

Downloaded from www.Manualslib.com manuals search engine You should look for this on the oil container, and use
only those oils that are identified as meeting GM
Standard 4718M and have the Starburst symbol on the
front of the oil container.
Your Corvette engine is filled at the factory with a
Mobil
l@ synthetic oil, which meets all requirements
for your vehicle.
Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M
may not be available. You can add substitute oil
designated SAE 5W-30 with the “Starburst” symbol at
all temperatures. If temperatures are above
0 OF (- 18 O C),
you may substitute
SAE low-30 with the “Starburst”
symbol. Substitute oil not meeting GM Standard
GM4718M should not be used for an oil change.
Engine Oil Additives
Don’t add anything to your oil. Your dealer is ready to
advise if you think something should be added.
When to Change Engine Oil
Your Corvette has an Engine Oil Life Monitor. This
feature will let you know when to change your oil and
filter
-- usually between 3,000 miles (5 000 km) and
10,000 miles (16
000 km) since your last oil change. Under severe conditions, the indicator may
come on
before
3,000 miles (5 000 km). Never drive your vehicle
more than 10,000 miles (16
000 km) or 12 months
(whichever occurs first) without an oil change. Use
engine oil meeting the GM Standard GM47 18M.
The system won’t detect dust in the
oil. So, if you drive
in a dusty area, be sure to change your oil every
3,000 miles
(5 000 lun) or sooner if the CHANGE OIL
light comes on. Remember to reset the Engine Oil Life
Monitor when the oil has been changed. For more
.information, see “Engine Oil Life Monitor” in the Index.
When Changing the Engine Oil
There is a special procedure for changing engine oil,
contact your dealer for additional information or the
procedure can be found in a Corvette Service Manual.
To purchase a service manual, see “Service and Owner
Publications” in the Index.
How to Reset the Engine Oil Life Monitor
Press RESET to acknowledge the CHANGE OIL SOON
warning. The oil page will then show a message such as
OIL LIFE
0%. To reset the monitor, press and hold
RESET for two seconds. You will then receive a
message such as OIL LIFE
99%.

(80 000 km) if the vehicle is mainly driven under one of
these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90 OF (32 O C) or higher.
In hilly or mountainous terrain.
High performance operation.
If you do not use your vehicle under one of
these conditions. Change the fluid and filter every
100,000 miles (166 000 km).
See “Scheduled Maintenance Services” in the Index for
the proper service intervals for the transmission fluid
and filter.
Manual Transmission Fluid
When to Check
How to Check
Because this operation can be difficult, you may
choose to have this done at your Chevrolet dealership
Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading.
NOTICE:
Too much or too little fluid can damage your
transmission. Too much can mean that some
of the fluid could come out and fall on hot exhaust system parts, starting a fire. Be sure
to
get an accurate reading if you check your
transmission fluid.
A good time to have it checked is when the engine oil
is changed. However, the fluid in your manual
transmission doesn’t require changing. Check the fluid level
only when your engine is off, the
vehicle
is parked on a level place and the transmission is
cool enough for you to rest your fingers on the
transmission case.

Downloaded from www.Manualslib.com manuals search engine How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise
the level to the bottom of the filler plug hole.
What to Use
To add lubricant when the level is low, use Axle
Lubricant (GM Part
No. 12345977) or SAE 8OW-90
GL-5 gear lubricant. To completely refill after draining,
add
4 ounces (1 18 ml) of Limited-Slip Differential
Lubricant Additive (GM Part
No. 1052358). Then fill to the bottom
of the filler plug hole with Axle Lubricant
(GM Part No. 12345977) or SAE 8OW-90 GL-5
gear lubricant.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, see “Engine Overheating” in
the Index.
A
50/50 mixture of water and DEX-COOL@
coolant will:
0 Give freezing protection down to -34°F (-37°C).
8
0 Give boiling protection up to 265 “F (129” C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gauges work as
they should.
