Downloaded from www.Manualslib.com manuals search engine Gas Cap-The fuel tank filler cap
has a
"Screw-on ratcheting type"
feature for proper gas tank sealing.
To remove:
• Rotate ~ap counterclockwise to
clear
the inside of the filler neck.
This will allow any residual
pres­
sure t!J escape.
• To iQstall, reverse this procedure
and . tighten cap securely until a
"ratcheting", . clicking sound is
heard indicating proper cap to
filler neck sealing.
NOTE: If this cap requires a re­
placement , only a cap with these
same features should
be used. Fail­
ure to use the correct cap can result
in a serious malfunction of the
sys­
tem. Correct replacement caps may
be obtained from your authorized
Chevrolet dealer.

Engine Oil and Filter
Recommendations
• Use only SE engine oil.
• Change oil each 6 months or
7,500 miles, whichever occurs
first ,
except under the following
conditions:
•
-driving in dusty conditions
-trailer pulling '
-extensive idling
-short-trip operation at freez-
ing
ternperatures( engine not
thoroughly warmed-up).
'Under these conditions, change oil
each 3 month s
or 3,000 miles,
whichever occurs first.
• Operation in dust stOmlS may
require an immediate oil change.
• Replace the oil filter at the first
oil change, and every second oil
change thereafter. AC oil filters
5-2
provide excellent engine pro­
tection.
See your Chevrolet dealer for ad­
vice on the frequency of' oil and
filter changes under unusual driving
conditions.
The above recommendations
ap­
ply to the first change as well as
subsequent oil changes. The oil
change interval for your Chevrolet
engine
is based on the use of SE
oils and quality oil filters. Oil
change intervals longer than those
listed
above will seriously reduce
engine life and may affect
Chevro­
let obligation undetthe provisions
of the New Vehicle Warranty.
NOTE: Non-detergent and other
low quality oils are
sgecifically not
recommended .
Only the use of SE
engine oils and proper oil and filter
change intervals assure you of
con­
tinued proper lubrication of your
Chevrolet engine.

stalled in
your engine at the factory.
It is not necessary to change this
factory-irtstalled oil prior to the
recommended normal chartge pe­
riod . However , check the oil level
more frequently during the break­
in period since higher oil consump­
tion is normal until the piston rings
becom e sea ted.
Recommended Viscosity
To help assure good cold and hot
starting, as well as maximum en­
gine life, fuel economy and oil
economy , select the proper oil vis­
cosity for
the temperature range
anticipated from the following
chart:

Checking Engine Oil Level
The engine oil should be main­
tained
at proper level. The best
time
to check it is as the last step in
a fuel stop. This will allow the oil
accumulation in
the engine to drain
back in the crankcase.
To check the
level, remove the oil gauge rod (dip
stick), wipe it clean and reinsert it
firmly for an accurate reading. The
oil gauge rod is marked
"FULL"
and "ADD." The oil level should be
maintained in the safety margin,
neither going above the
"FULL"
line nor below the "ADD" line.
Re sea t the gauge firmly after taking
the reading.

Hinges
The following points should be
checked and lubricated every 6
months or
7,500 miles, whichever
occurs first: hinges on all doors,
fuel filler door, trunk lid, door lock
striker and door jamb switches.
Hood Latches
Every 6 months or 7,500 miles

as follows:
1. Wipe off any accumulation of
dirt or contamination on latch
parts.
2. Apply Lubriplate
or equivalent

Air Conditioning
Have your Chevrolet Dealer
check your Air Conditioning
sys­
tem at some time during the winter
months to be sure there has been
no loss in cooling output. During
the summer, see your Chevrolet
Dealer immediately if you suspect
the system
is nof performing as it
should.
NOTE: Your car's air condition­
ing system will not operate be­
low ambient temperatures of 300P
( -1°C) regardless of control

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
plait) water;
In geographic areas having 11
heavy concentration of such COr­
rosive materials , it is recommended
that the comple te 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 under coating mate­
rials which will help protect your
vehicle from corrosion.

Vehicle Loading
When inftiltedas recommended

satisfactorily at all normal highway
loads
and s peeds. Do not load your
vehicle beyond the capacity shown

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
fuef economy.
Fuel Selection '
Your vehic1eis designed to op­
erate only 011 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. Onleadedgasoline
is essential
for proper emission co ntrol 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.

Downloaded from www.Manualslib.com manuals search engine Air Cleaner
Your Cl:
receives its power from
a
mixture of gasoline and air. The
air is taken into the system through
the air cleaner so it's important to
replace~he air cJea!1er at required
intervals. A dirty
air cleaner re­
duces . engine efficiency.
Properly Tuned'Engine
Overall tuning (a check on tlin­
ing , spark plugs, emission control
devices, etc;)
can improve your
car's gas mi,leage . You just
can't
expect an "out-of-tune" engine to
give you good gas mileage and
cleaner air.
Excess Weight
Fuel economy is related to the
work. the engine . must do. The
heavier the load , the more power it
take
s. Keep excess weight to a
minimum by removing any per­
sonal effects or luggage from the
car or trunk when they are not
needed.
Tire Inflation
Underinfiation not only causes
needless wear of the tires, but
can
also waste gasoline. It's a good
idea to check tire pressures
regularly.
Wheel Alignment
Incorrect "toe in" or "toe out" can
have the effect,of dragging your
front tires sideways
and may cause
premature tire wear.
It takes power
to carry this extra load and that
takes gas from your tank.
Catalytic Converter
The catalytic converter is an
emi ssio n control device added to
5-22 the
exhaust system to reduce hy­
drocarbon
and carbon monoxide
pollutants from the exhaust gas
stream. The converter contains
beads which are coated with a cata­
lytic material containing platinum
and palladium.
Use of the catalytic converter
has the advantage
of allowing the
engine
to be re-tuned for improved
fuel economy anddriveability.
The catalytic converter requires
the use
of unleaded fuel only,
Unleaded gasoline is used to re­
duce combustion chamber deposits,
corrosion
and to prevent lead con­
tamination
of the catalyst that
would render it ineffective.
The use
of leaded fuel will cause the COIO- .
lytic converter to become ineffec­
tive
as an emission control device.
