The time or mileage intervals on
the following pages are intended
as a guide for establishing regular
maintenance and lubrication per­

or
operation under adverse conditions
may necessitate more frequent ser­

Fuel
Requirements
Your Chevrolet engine is de­
signed to operate only on unleaded
gasoline. Unleaded gasoline
is essen­
tial for proper emission control

mize spark plug fouling. The

For owner convenience, a sepa­
rate maintenance folder has been
provided with your car which con­
tains a complete schedule

Use unleaded gasoline meeting
the minimum octane specifications
established
by the Federal govern­

Every 30,000 miles-clean and
repack with a high melting point
wheel bearing lubricant.
Use wheel
bearing lubricant GM
Part No.
1051344 or equivalent. This
is a
premium high melting point lubri­
cant. When replacement
is neces­
sary specify Delco parts.
Brakes
Brake linings should be periodi­
cally inspected for wear by a quali­
fied technician. The frequency of
this inspection depends upon driv­
ing conditions such
as traffic or
terrain, and also· the driving tech­
niques of individual owners. Your
Chevrolet Dealer
is best qualified
to advise you as to how often this
inspection should be performed.
When replacement
is required,
specify GM and Delco parts.
REMINDER: The front disc
brakes have a built-in wear indica­
tor that
is designed to make a high
frequency, squealing or cricket-like
warning sound when the linings are
worn to where replacement
is re­
quired. The sound will occur inter­
mittently or continuously when
wheels are rolling, but will dis­
appear when the brake pedal
is
firmly applied. Also see the brake
checks listed in the Maintenance
Schedule folder.

MAINTENANCE
The effects of salt and other cor­
rosive materials used for ice and
snow removal and dust control can
result in accelerated rusting and
deterioration of underbody com­
ponents such
as brake and fuel
lines, frame, underbody floor pan,
exhaust system, brackets, parking
brake cables, etc. These corrosive
effects, however, can be reduced
by periodic flushing of the under­
body with plain water.
In geographic areas having a
heavy concentration of such cor­
rosive materials, it
is recommended
that the complete underbody be
inspected and flushed at least once
each year, preferably after a win­
ter's exposure. Particular atten­
tion should
be given to cleaning
out underbody members where dirt and
other foreign materials may
have collected.
If desired, your Chevrolet dealer
can perform this service for you.
In addition ,
he can provide recom­
mendations
on undercoating mate­
rials which will help protect your
vehicle from corrosion.

Downloaded from www.Manualslib.com manuals search engine IMPORTANT FACTS YOU SHOULD KNOW ABOUT GASOLINE MILEAGE
How you drive, where you drive,
and when you drive all have an
effect on how many miles you can
get from a gallon of gasoline. The
careful attention you give your car
as far as maintenance and repairs
are concerned will also contribute
importantly to fuel economy.
Fuel Selection
Your vehicle is designed to op­
erate
only on unleaded gasoline of
at least 87 average octane num­
ber (Research octane plus Motor
octane divided by two). This gaso­
line should have a Research octane
number of at least 91, and a
Motor octane number of
at least
83. Unleaded gasoline
is essential
for proper emission control system
operation, and it will minimize
spark plug fouling. The use of
... AND HOW TO IMPROVE IT
leaded gasoline can damage or
severely reduce the effectiveness of
the emission control system and re­
sult in loss of warranty coverage.
"Jackrabbit" Starts
Gasoline can be conserved (and
engine and tire life prolonged) by
avoiding unnecessarily rapid accel­
eration away from lights and stop
signs.
Stop-And-Start Driving
Frequent stops and starts during
a trip really cut down on your miles
per gallon.
Plan even your short
shopping trips to take advantage of
through streets to avoid traffic
lights.
Pace your driving like the
professional drivers to avoid
un­
necessary stops.
5-21
Excessive Idling
An idling engine uses gasoline,
too.
If you're faced with more than
a
few minutes wait and you're not
in traffic, it may be better to
"turn
off"
and start again later.
Sudden Stops
Sudden stops themselves don't
waste gasoline , but energy
is
wasted as heat in braking . Energy
in the form of gasoline
is also
needed to accelerate back to driv­
ing speed.
Lubricants
A properly lubricated vehicle
means less friction between moving
parts. Consult this manual and the
maintenance schedule for the
proper lubricants to use and the
lubrication intervals.
