oil viscosity CHEVROLET CAMARO 1994 4.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you keep driving your vehicle with
this light on, after a while the emis-
sion controls won’t work as well,
your fuel economy won’t be as good
and your engine may not run as
smoothly. This could lead to costly
repairs not covered by your warranty. 80 I// //

Engine Oil Pressure Gage
This gage tells you if there could be a
problem with your engine oil pressure.
The engine oil pressure gage shows the
engine oil pressure in psi (pounds per
square inch)
in the U.S., or kPa
(kilopascals) in Canada, when the engine
is running. Oil pressure should be
20 to
80 psi (140 to 550 kPa). It may vary with
engine speed, outside temperature and
oil viscosity, but readings above the red
area show the normal operating range.
Readings in the red area tell you that the
engine is low on oil, or that you might
have some other
oil problem. See “Engine
Oil”
in the Index.
~~~
NOTICE:
Damage to your engine from
neglected oil problems can be costly
and is not covered by your warranty.

Don’t add too much oil. If your engine
has
so much oil that the oil level gets
above the cross-hatched area that shows the proper operating range, your engine
could be damaged.

where
in the proper operating range. Push

way back in when you’re

What Kind of Oil to Use:
Beginning midyear 1993, oils of the
proper quality for your vehicle will be
identified with
this new “starburst”
symbol. The “starburst” symbol
indicates that the
oil has been certified
by the American Petroleum Institute
(API), and
is preferred for use in your
gasoline engine.
You should look for this on the front of
the
oil container, and use only oils that
display this new symbol.
You should also use the proper
viscosity
oil for your vehicle, as shown
in the following chart.

As shown in the 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 1OW-40 or SAE 20W-50.
[f you cannot find oils with the new
‘starburst” symbol on the front of the
;ontainer, you should look for and use
3ils containing the following three
:hings:
SH or SG
“SH’ or “SG” must be on the oil
container
, either by itself or
combined with other quality
designations, such as “SH/CD,”
“SH, SG, CD,” “SG/CD,” etc. These
letters show American Petroleum
Institute
(API) levels of quality.
SAE
5W-30
Energy Conserving I1
Oils
with these words on the
container will help you save fuel. These
three things are usually included
in a doughnut shaped logo (symbol) on
most containers.
If you cannot find oils
with the “starburst” symbol, you should
look for oils with the doughnut shaped
symbol, containing the three things
noted above.
NOTICE:
If you use oils that do not have
either the “starburst” symbol or an
API SH or SG designation, you can
cause engine damage not covered
by your warranty.
GM Goodwrench@ oil (in Canada, GM
Engine Oil) meets all the requirements
for your vehicle.
Engine Oil Additives:
Don’t add anything to your oil. Your
Chevrolet dealer
is ready to advise if
you
think something should be added.

Explanation of Scheduled
Maintenance Services
Following are explanations of the services
listed in Schedule
I and Schedule 11.
The proper fluids and lubricants to use are
listed
in Section D. Make sure whoever
services your vehicle uses these. All parts
should be replaced and all necessary
repairs done before you or anyone else
drives the vehicle.
NOTE: To determine your engine’s
displacement and code, see
“Engine Identification”

Chassis Lubrication
- Lubricate
the suspension and steering
linkage. Lubricate the
transmission shift linkage.
Tire and Wheel Rotation and
InsDection
- For proper wear
and maximum tire life, rotate
your tires following the
instructions
in this manual. See
“Tires, Inspection and Rotation”
in the Index. Check the tires for
uneven wear or damage. If you
see irregular or premature wear,
check the wheel alignment.
Check for damaged wheels also.
Engine Accessory Drive Belt(s)
Inspection
- Inspect the belt(s)
for cracks, fraying, wear and
proper tension. Replace as needed. (Belts can have many
small cracks
in individual ribs
without affecting performance.)
ITEM
NO. SERVICE
5 Cooling System Service* -
Drain, flush and refill the system
with new or approved recycled
coolant conforming to
GM
Specification 1825M. Keep
coolant at the proper mixture as
specified. See “Coolant”
in the
Index. This provides proper
freeze and boil protection,
corrosion inhibitor level and
maintains proper engine
operating temperature.
Inspect hoses and replace
if they
are cracked, swollen or deterior-
ated. Tighten screw-type hose
clamps. Clean the outside
of the
radiator and air conditioning
condenser. Wash the pressure
cap and neck.
To help ensure proper operation,
we recommend a pressure test of
both the cooling system and the
pressure cap.
