1996 CHEVROLET CORVETTE oil additives

Downloaded from www.Manualslib.com manuals search engine In Canada, some gasolines contain an octane enhancing
additive called MMT.
If you use such fuels, your
emission control system performance may deteriorate
and the malfunction indicator lamp on your instrument
panel may also turn on. If this happens, return to your
authorized Corvette dealer for service.
To pfovide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming
in your engine and fuel system, ailowing your
emission control system to function properly. Therefore,
you should not have to add anything to the fuel.
In
addition, gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may be
available in your area to help clean the air. General
Motors recommends that you use these gasolines
if they
comply with the specifications described earlier.
I NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in
the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell us where you’re going and give your
Vehicle Identification Number
(VIN).

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 20W-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.
You should look for this on the oil container, and use
only those oils that are identified as meeting GM
Standard GM4718M 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: 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 at all
temperatures.
If temperatures are above 0” F (- 18 ” C),
you may substitute SAE 1OW-30 with the “Starburst”
symbol. Substitute oil not meeting GM Standard
GM47 18M should not be used for an oil change.
Engine Oil Additives
Don’t add anything to your oil. Your Corvette dealer is
ready to advise
if you think something should be added.

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL TM (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM
Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need to add anything else.
Adding only plain water to your cooling system
can be dangerous. Plain
water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and
you or
others could be burned. Use
a 50/50 mix of clean
water and
DEX-COOL TM (orange-colored.
silicate-free) antifreeze.
NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by your
warranty. Too much water in the
mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
