Downloaded from www.Manualslib.com manuals search engine Break-in Schedule
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
age for which the Chevrolet Divi­
sion
is not responsible under the
terms
of the Chevrolet New
Vehicle Warranty.

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

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

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
