1995 CHEVROLET CORVETTE oil temperature

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.

To add lubricant when the level is low, use Axle
Lubricant (GM Part
No. 12345977) or SAE SOW-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 following explains your cooling system and how to
add coolant when it is low.
If you have a problem with
engine overheating or if you need to add coolant to your
high fill reservoir, see “Engine Overheating” in the
Index.
The proper coolant for your Corvette will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262 “F (128 ” C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should. Use a mixture
of one-half
clean water (preferably
distilled) and one-half antifreeze that meets
“GM
Specification 1825M,” which won’t damage aluminum
parts.
You can also use a recycled coolant conforming to
GM Specification 1825M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant flush and refill. If
you use
this mixture, you don’t need to add anything else.
