Your car is designed to operate
on unleaded fuel of approximately
91 research octane number.
If you plan to operate your car
outside the Continental limits of
the United
States or Canada, there
is a possibility that the best fuels
available in some countries are so
low in octane rating that excessive
knocking and serious engine
dam­
age may result from their use. Also ,
if leaded fuels are used in vehicles
designed for unleaded fuels, it may result
in the deactivation of the
catalytic converter, if the vehicle
is
so equipped, and possibly other
related problems.
The use of leaded
fuel in a vehicle designed
for un­
leaded fuel will require different
maintenance intervals.
To obtain in­
formation on the octane rating and
availability of non-leaded fuels
available in the countries in which
you plan to travel, and a mainte­
nance schedule to be used when
operating on leaded fuel, write to

It is recommended that you not
operate your car in any country not
having fuels meeting the require­
ments of your car's engine
as these
may cause engine damage for which

the terms of the Chevrolet New
Vehicle Warranty or Emission

The time or mileage intervals on

as a guide for establishing regular

Your Chevrolet engine is de­

gasoline. Unleaded gasoline
is essen­

Use unleaded gasoline meeting

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.

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.
