If you have the LT1 engine, it’s a good idea to check
your engine oil level every time you get fuel. In order to
get
an accurate reading, the oil must be warm and the
vehicle must be on level ground.
Turn
off the engine and give the oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the actual level. If
you have the LT5
~ engine,
the best time to ~ check your engine oil
is when the engine is cold.
If
you run the engine, the engine oil won’t drain back
into the pan fast enough. Give the oil two hours to drain
back into the oil pan.
If you don’t, the oil dipstick might
not show the actual level.

To Check Engine Oil
Pull out the dipstick and clean it with a paper towel or a
cloth, then push it back in all the way. Remove it again,
keeping the tip down.

When to Add Oil
If the oil is at or below the ADD mark you’ll need to
add some oil.
But you must use the right kind. This part
explains what kind of oil to use.
For crankcase capacity,
see “Capacities and Specifications” in the Index.
NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.

Just fill it enough
to put the level somewhere in the
proper operating range. Push the
dipstick all the way back in when
you’re through. What Kind of Oil to Use
Look for two things:
0 GM4718M
The Corvette engine requires a special oil meeting
GM Standard GM4718M. Oils meeting this Standard
may be identified as synthetic. However, not all
synthetic oils will meet this GM Standard. You
should look for and use only an oil that meets GM
Standard GM47 1 8M.
NOTICE:
If you use oils that don’t have the GM4718M
Standard designation, you can cause engine
damage not covered by your warranty.

FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST
SAE VISCOSITY GRADE OIL FOR THE EXPECTED TEMPERATURE MNGE.

LOOK
FOR THIS
SYMBOL
-- 1-J SAE 1OW-30
SAE 5W-30 PREFERRED
COLD
WEATHER
DO NOT USE SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
SAE 5W-30
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 (-1S.OC) or above.
These numbers on an
oil container show its viscosity,
or thickness.
Do not use other viscosity oils such as
SAE
20W-50.
Oils meeting these
requirements should also
have the “Starburst” symbol
on the container.
The “Starburst” symbol indicates that the
oil has been
certified by the American Petroleum Institute (API), and
is preferred for your gasoline engine. These oils may
also be identified
as API SH.

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
1 @ synthetic oil, which meets all requirements for
your vehicle.
Substitute Oil (LTl Only): When adding oil to
maintain engine oil level, oil meeting GM Standard
GM47
18M may not be available. You can add substitute
oil designated
SAE 5W-30 with the “Starburst” symbol
or API Service SH at all temperatures. If temperatures
are above
0” F (- 18 O C), you may substitute SAE
1OW-30 with the “Starburst” symbol or API Service
SH
oil. This oil should not be used for an oil change.
Substitute Oil (LT5 Only): When adding oil to
maintain engine oil level,
if an oil meeting GM Standard
GM47
18M is not available, you can use oil designated
SAE 1OW-30 with the “Starburst” symbol or API
~ Service SH at all temperatures. This oil should not be
used for
an oil change.
Engine Oil Additives
Don’t add anything to your oil. Your Chevrolet dealer is
ready to advise if you think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
0 Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop and
go traffic).
Most trips are through dusty areas.
If any one of these is true for your vehicle, you need to
change your oil and filter every 3,000 miles
(5 000 km)
or 3 months -- whichever comes first. (See “Engine Oil
Life Monitor” in the Index.)
If none of them is true, change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
comes first. (See “Engine Oil Life Monitor” in the
Index.)
Engine Coolant Heater
An engine coolant heater can be a big help if you have
to
park outside in very cold weather, 0” F (- 1 8 O C) or
colder. If your vehicle has this feature, see “Engine
Coolant Heater” in the Index.

Downloaded from www.Manualslib.com manuals search engine What to Do with Used Oil
Did you know that used engine oil contains certain
elements that
may be unhealthy for your skin and could
even cause cancer? Don’t 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 throw away
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 real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose
of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it
by taking it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.
Air Cleaner
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See “Scheduled Maintenance Services” in the Index.
