Downloaded from www.Manualslib.com manuals search engine If your fuel filler door release won’t operate, there is a
manual release tab. The tab is located against the upper
trim on the driver’s side in the rear compartment. While
refueling, place the cap in the holder on the fuel
filler door to prevent damage to your vehicle’s finish.
To remove the cap, turn it slowly to the left
(counterclockwise). The cap has a spring in it; if you let
go of the cap too soon, it will spring back to the right.

(clockwise) until you hear a clicking sound. Make sure
you fully install the cap.
/9 CAUTION:
If J ,.I get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on you
if you open the
fuel filler cap too quickly. This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then unscrew
the cap all the way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See “Cleaning the
Outside of Your Vehicle” in the Index.
I NOTICE:
If you need a new cap, be sure to get the right
type. Your dealer can get one for you.
If you get
the wrong type, it may not fit or have proper
venting, and your fuel tank and emissions system
might be damaged.

If the LOW OIL LEVEL message on the Driver
Information Center comes on, it means you need to
check your engine oil level right away. For more
information, see “Driver Information Center” in the
Index. You should check your engine oil level regularly;
this is an added reminder.
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.
The engine oil dipstick is
next to the coolant surge
tank. The dipstick handle is
a round, yellow loop.
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.
Checking 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 Engine Oil
If the oil is at or below the ADD mark, you’ll need to
add at least one quart of 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.

Page 258 of 378
Downloaded from www.Manualslib.com manuals search engine I 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.
The engine oil fill cap is on
top of the right valve rocker
arm cover.
Be sure to 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 Engine Oil to Use
Look for two things:
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 18M.
FNOTICE:
If you use oils that don’t have the GM4718M
Standard designation, you can cause engine
damage not covered by your warranty.

These numbers on an oil container show its viscosity,
or thickness.
Do not use other viscosity oils such as
SAE

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%.
