oil viscosity CHEVROLET S10 1996 2.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine Engine Oil Pressure Gage
The oil pressure gage shows
the engine oil pressure
in
psi (pounds per square inch)
when the engine is running.
Canadian vehicles indicate
oil pressure in
kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature
and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low oil level or other problems causing low
oil pressure.
A CA"T1ON:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
1 NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.

Downloaded from www.Manualslib.com manuals search engine What Kind of Oil to Use
Oils recommended for your vehicle can be identified by
looking for
the “Starburst” symbol. 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.
If you change your own oil, be sure you use oil that has
the Starburst symbol on the front of the oil container. If
you have your oil changed for you, be sure the oil put
into your engine is American Petroleum Institute
certified for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

Downloaded from www.Manualslib.com manuals search engine 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 20W-50. 7
NOTICE:
Use only engine oil with the American
Petroleum Institute Certified For Gasoline
Engines “Starburst” symbol. Failure to use
the recommended oil can result in engine
damage not covered by your warranty.
GM Goodwrench’ oil meets all the requirements for
your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your GM dealer is ready
to advise
if you think something should be added.
When te Change Engine Oil
See if any one of these is true for you:

e
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).
You operate your vehicle in dusty areas or off-road
frequently.
You frequently tow a trailer.
The vehicle is used for delivery service, police, taxi
or other commercial application. I
Driving under these conditions causes engine oil to
break down sooner.
If any one of these is true for your
vehicle, then you need to change your oil and filter
every 3,000 miles
(5 000 km) or 3 months -- whichever
occurs first.
If none of them is true, change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
