NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow the
engine to cool before attempting any repair. The
engine oil will be severely degraded. Repair the
cause of coolant loss, change the oil and reset the
oil life monitor. See ªEngine Oilº in the Index.
If Steam Is Coming From Your Engine
CAUTION:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.

Your Corvette engine is filled at the factory with a
Mobil 1
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 ªStarburstº symbol at
all temperatures. If temperatures are above 0F (
-18C),
you may substitute SAE 10W
-30 with the ªStarburstº
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 vehicle has a computer that lets you know when to
change your engine oil. This is not based on mileage,
but on engine revolutions and engine operating
temperature. When the computer has calculated that the
oil needs changing, the Oil Life Monitor will indicate
that a change is necessary. The mileage between oil
changes will vary depending on how you drive your
vehicle
-- 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 GM4718M.
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 km) or sooner if the CHANGE OIL
SOON message comes on. Remember to reset the
Engine Oil Life Monitor whenever the oil is changed.
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 ªService and Owner
Publicationsº in the Index.
How to Reset the Engine Oil Life Monitor
To reset the monitor after an oil change:
1. With the ignition on, press the TRIP button so the
OIL LIFE percentage is displayed.
2. Press RESET and hold for two seconds. The word
RESET will appear, then OIL LIFE 99%.

Scheduled Maintenance

7-6Engine Oil Scheduled Maintenance

first). Reset the monitor. The monitor will show you
when to change the oil
-- 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 without an oil change. Use engine oil
meeting the GM Standard GM4718M.The Engine Oil Life Monitor 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 km) or sooner if the
CHANGE OIL SOON message comes on. Remember to
reset the Oil Life Monitor when the oil has been
changed. See ªEngine Oil Life Monitorº in the Index for
more information on resetting the monitor.
