In addition to the new car
break-in instructions in this man
ual, it
is recommended that your
new Camaro be operated for
500
miles before trailer towing. If it is
necessary to tow during this period,
avoid speeds over
50 MPH and full throttle
starts. The same precau
tions should be observed whenever
a new engine, transmission
or axle
is installed in your car.
Operation in Foreign Countries
Your Camaro is designed to op
erate on fuel of approximately
91
research octane number or higher,
sold in the United States and Can
ada.
If you plan to operate your
Camaro outside the continental
limits of the United States
or Can
ada, there
is a possibility that the
best fuels available in some coun
tries are so low in anti-knock
quality that excessive knocking
and serious engine damage may
. result from their use. To obtain
information on the quality of fuels available
in the countries in which
you plan to travel , write to Chevro
let Motor Division, Service Depart
ment, Detroit, Michigan
48202,
(or in Canada write to General
Motors of Canada Limited,
Owner
Relations Department , Oshawa,
Ontario),
giving:
• The vehicle identification num
ber ( on plate on instrument
panel ahead of the steering
wheel and visible through the
windshield , or from registration
slip or title).
• The country or countries in
12
which you plan to travel.
It
is recommended that you not
operate your Camaro in any coun
try not having fuels meeting the
requirements of
your Camaro
engine. Engine modifications are
not available to compensate for
low anti-knock quality fuels. Op
eration of your car under condi
tions of continuous
or excessive
knocking constitutes misuse of the
engine and may cause engine dam

Gas Cap-The fuel tank filler cap has
a new two-step removal and
installation procedure plus a pres
sure-vacuum safety relief valve. It
is equipped with a double set of
locking tangs. To remove:
• Rotate cap one-half turn coun
terclockwise to clear the first set
of tangs from the slots inside the
filler neck. This will allow any
residual pressure to escape.
• Pull the cap outward and rotate
one-quarter turn counterclock
wise to clear second set of tangs
and remove the cap.
• To install, reverse this procedure.
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 re
sult in a serious malfunction of the
system. Correct replacement caps
may be obtained from your Au
thorized Chevrolet Dealer.

Engine Oil and Filter
Recommendations
• Use only SE engine oil.
• Change oil each 4 months or
6,000 miles. If more than 6,000
miles are driven in a 4-month
period, change oil each
6,000
miles.
• Change oil each 2 months or
3,000 miles, whichever occurs
first, under the following con
ditions: - driving in dusty conditions,
-trailer pulling,
- extensive idling,
- short-trip operation at freez-
ing temperatures (engine not
II
thoroughly warmed-up).
• Operation in dust storms may
require an immediate oil change.
• Replace the oil filter at the first
oil change, and every second oil
change thereafter. AC oil filters
Page 52 of 85
Downloaded from www.Manualslib.com manuals search engine Checking Oil Level
The engine oil should be main
tained at proper level. The best
time to check it
is before operating
the engine or
as the last step in a
fuel stop. This will allow the oil ac
cumulation in the engine to drain
back in the crankcase.
To check
the level, remove the oil guage rod
(dip stick), wipe it clean and rein
sert
it firmly for an accurate read
ing. 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. Reseat the gauge firmly after
taking the reading.
Supplemental Engine Oil
Additives
The regular use of supplemental
additives
is specifically not recom
mended and will increase operat
ing costs. However, supplemental additives
are available that can
effectively and economically solve
certain specific problems without
causing other difficulties.
For ex
ample, if higher detergency
is re
quired to reduce varnish and
sludge deposits resulting from
some unusual operational diffi
culty, a thoroughly tested and ap
proved additive -
"Super Engine
Oil Supplement" -is available at
your Chevrolet dealer.
In the event
of an operational problem, consult
your dealer for advice before
us
ing supplemental additives.
Drive Belts
Every 6,000 miles or 4 months
inspect drive belts for wear , fray
ing, cracking , and tension. Belts
which are in poor condition should
be replaced immediately.
Check tension by applying mod
erate thumb pressure midway be
tween pulleys.
If the center-to-
49
center distance between pulleys is
13 to 16 inches, the belt should
deflect
1;2 inch . If the center-to
center distance
is 7 to 10 inches,
the belt should deflect
1;4 inch.
Loose belts should be retensioned
to give the correct deflection.
It is recommended that belts be
replaced every 24 months or
24,000
miles , whichever occurs first.

are carried.
The use of improper tire
infla
tion pressures can adversely affect
tire life and vehicle performance:
• Too little air pressure can result
in excessive tire heat, abnormal
tire wear, adverse handling and
reduced fuel economy.
• Too much air pressure can re
sult in abnormal tire wear, ad
verse vehicle ride and handling,
and increased susceptibility to
damage by road impacts.
Tire pressures should be
checked when the tires are "cold"
at least once a month (and pref
erably oftener) or before long
trips or when heavily loaded. The
following points should
be ob
served when checking and setting
tire pressures:
1. Cold tire pressure ratings are applicable when a vehicle has been Inoperative for 3 hours or more, or driven less
than 1 mile.
2. Tire Inflation pressure may Increase as
much as 6 pounds per square inch (psi)
when hot (aHer vehicle has been driven
10 miles or at speeds of more than 60 miles per hour). Do not "bleed" or reduce pressures when tires are hot from
driving.
3. For continuous high speed operation
(over 75 mph), Increase tire inflation
pressure 4 psi above the recommended
pressures up
to a maximum of 32 psi
cold pressure for load range B tires, 36
psi for load range C tires, or 40 psi for D load range tires. Sustained speeds
above 75 mph are not recommended
when the 4 psi adjustment would require pressures greater than the above
maximum pressures.
4. Always use a tire pressure gauge when
checking pressures as the appearance
of a tire can be deceiving. For example,
radial ply fires, In comparison with bias
ply tires at the same pressure, may have
the appearance of being under-inflated.
Vehicle Loading -Do not load
your vehicle beyond the vehicle
capacity (total pounds) shown on
the tire placard. This figure
repre
sents the design capacity of the ve
hicle, not merely of the tires.
58
When towmg trailers, the allow
able pasenger and cargo load
must be reduced by an amount
equal to the trailer tongue load on
the trailer hitch.
(See "Trailer
Hauling"
in Section 1 of this man
ual.) Station wagon loads should
be distributed
as far forward as
possible. Vehicles equipped with
luggage racks do not have a
ve
hicle load capacity greater than
specified on the tire placard.
Tire Wear and Rotation -Un
even or abnormal tire wear is usu
ally the result of incorrect inflation
pressure, improper wheel
align
ment, wheels being out-of-balance,
or poor driving habits.

Improper mounting can cause
vio
lent bursting of the tire away from
the wheel which can result in serious
personal injury.
Underbody Maintenance
The effects of salt and other
corrosive materials used for ice
and snow removal and dust
con
trol can result in accelerated rust
ing and deterioration of under
body components such
as brake
and fuel lines, frame, underbody
floor pan, exhaust system, brac
kets , parking brake cables. These
corrosive effects, however, can be
reduced by periodic flushing of the underbody
with plain water. In
geographic areas having a heavy
concentration of such corrosive
materials,
it is recommended that
the complete underbody be
in
spected and flushed at least once
each year, preferably after a
win
ter's exposure. Particular attention
should be given to cleaning out
underbody members where dirt
and other foreign materials may
have collected.
If desired, your Chevrolet deal
er can perform this service for
you.
In addition, he can provide
recommendations on undercoat
ing materials which will help
pro
tect your vehicle from corrosion.
Battery Care (Energizer)
Check fluid level monthly. If the
fluid level
is low, add only color-

Downloaded from www.Manualslib.com manuals search engine Important Facts You Should
Know About Gasoline
Mileage and How to
Improve It
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 on unleaded or low-lead fuels
>of at least 91 Research Octane.
These fuels minimize spark plug
fouling and emission system
de
terioration. Your engine does not
require premium fuel. Therefore,
its use would be an unnecessary
additional expense.
If the service
station gas pump has a symbol similar
to the following, use
un
leaded or low-lead gasoline with a
symbol of 2. A higher number
is
satisfactory but not required.
"Jackrabbit" Starts
Gasoline can be conserved (and
engine and tire life prolonged) by
avoiding unnecessarily rapid
ac
celeration away from lights and
stop signs.
Stop-And-Start Driving
Frequent stops and starts during
a. trip really cut down on your
64
miles per gallon. Plan even your
short shopping trips to take
advan
tage of through streets to avoid
traffic lights.
Pace your driving like
the professional drivers to avoid
unnecessary stops.
Speed Versus Mileage
Excessive speed on the highway
raises your gas consumption
dras
tically. Statistics prove that you
might save
as much as 19% on
your fuel bill by driving
50 MPH
instead of 70 MPH.
Excessive Idling
An idling engine uses gasoline,
too, (especially after a cold engine
start).
If you're faced with more
than a
few minutes wait you're
better
off to "turn off" and start
again later.
Sudden Stops
Sudden stops themselves don't
Page 68 of 85
Downloaded from www.Manualslib.com manuals search engine waste gasoline, but energy is wasted
as heat in braking. Energy in the
form of gasoline
is also needed to
accelerate back to driving 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.
Automatic Choke
Your automatic choke should be
checked periodically
as it regulates
the gasoline/air mixture used in
starting and warming the engine.
Properly Tuned Engine
Overall tuning (a check on tim
ing, distributor points, spark plugs,
emission control· devices , etc.) can
improve your car's gas mileage.
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 takes. Keep excess weight to a
minimum by removing . any per
sonal effects or luggage from the
65
car or trunk when they are not
needed.
Tire Inflation
Under inflation not only causes
needless wear of the tires, but can
also waste gasoline. It's a good
idea to check tire pressures regu
larly.
Wheel Alignment
"Toe in" or "toe out" has the
effect of dragging your front tires
sideways and causes premature tire
wear.
It takes power to carry this
extra load and that takes gas from
your tank.
