reaf brakes reducing their effectiveness and causing excessive wear or damage,
DISC BRAKE WEAR INDICATORS
Front disc brakes have built-in wear indicators that are designed to make a
high-pitched
squealing or cricket-like warning sound when the brake linings are
worn 10 where -new linings are needed. The sound will come and go, or be heard
all the time
when the wheels are rolling, and when the brake pedal is pu~hed down
firmly . Expensive damage can result
if linings are not replaced when needed.

EMPTY, some fuel is still available as a reserve. When
the gage registers
FULL. some additional" fuel can"still be added to the tank. The
following conditiqns may be considered normal:
• Gas station _pump may shut off before fuel gage indicates FULL. •
•
Amount of gasoline required for fill-up may not exactly correspond to gage.
• Needle may not move away from FULL until some time after fill·up.
• Needle may !Dove during turns. stops and-accelerations.
When the ignition switch
is turned to the OFF position, the needle will not

Downloaded from www.Manualslib.com manuals search engine On all C-4 cars, a "CHECK ENGINE" light on the instrument panel is
designed to come on during engine starting , to let you know the bulb is working. (The light will stay on a short time after the engine starts.) If the light comes on while driving, service to the emission control system
may be required. See your Chevrolet dealer' as soon as possible for an inspection of the system. Continued driving without having the C-4 System serviced _ could eventually
cause damage
to the emission control system . It could also affect fuel
e conomy and drivabili -ty.
ENGINE OIL AND FILTER RECOMMENDATIONS • Engine oils' are labeled on 'the containers with various API (American
Petroleum Institute) designations 6f quality. Use engine oils that are labeled
5E or SE/CC. Do not use oils labeled only SA, 5B, 5C, SD, CA, CB, CC or CD; _or oils with the combination label SE and CD (SE/CD). Higher
quality oils labeled SF will be introduced soon (late 1979, or 1980). These SF oils are preferred and should be used when available.
• The oil and filter change intervals for your engine are based on the use of SE-quality or SF-quality oils and ,high- quality filters such as AC oil filters. Using oils other than SE-quality or SF-quality oils, or oil change intervals
longer than recommended. could reduce -engine life and might affect your
warranty.
• Your engine was filled with a high·quality engine oil when it was built. You do ,not have to change this oil before the suggested change period.
•
If your normal driving does nQt include one or more of the four "severe service" conditions listed below. change the oil every 7,500 miles (12 000 ' kilometers) or 12 months, whichever comes first. Change the oillilter at the
first oil change. then every second oil change, if mileage (7,500 miles or 12
000. kilom~ters) determines .w ,hen you change the oil. If _time (12 months)
determines when you change the oil, change the filter with every oil change.
• Change the oil and oil filter every 3,000 miles (4 800 kilometers) , or three
months if you often drive under one or more of these 'severe service·,~.
conditions: • Driving in dusty areas
• Towing ,3 trailer
• Frequent idling or idling for long periods
• Driving 4 miles (6 kilometers) br'less in freezing weather,o~other short trips in cold weather, where the engine does not thoTough ,ly warm up.
• Change the oil and oil filter as soon as -possible after driving in a dust
storm.
Oil Viscosity
Engine oil viscosity (thickness) has an effect on fuel economy. Lowec viscosity
engine oils can provide increased , fuel " economy; however, higher temperature
weather conditions require higher viscosity engine oils for satisf~ctory lubrication.
To. get the best fuel economy with your-1980 Chevrolet, -iou should use -,, ' .
fuel. 'saviiJ.&:_engine oil ohhe_ proper viscosity. These oils call_ be found. in serviCe
stations and other retail stores. They are-identified by words such as: "Energy Saving," "Conserves Gasoline," "Gas Saving," "Gasoline Saving," '''Friction
Reducing," "Improved Gasoline Mileage" or "Fuel Saving."
The following chart lists the engine ' oil viscosities recommended for the
temperature range you expect before the next oil change. For lemperalures above ,_18°C (O"F),SAE lOW-30 is -the preferred viscosity grade. Ircold-weather starting
problems
are encountered at temperatures below -lSoC ( oils may be required.
