1976 CHEVROLET VEGA catalytic converter

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
Chevrolet Motor Division,
Service
Department, Detroit, Michigan
48202, (or in Canada write to
General Motors of Canada Limited,
Owner Relations Department,
Oshawa, Ontario LlJ 5Z6), giving:

• The vehicle identification num­
ber (on plate on instrument
panel ahead of the steering wheel
and visible through the wind­
shield,
or from registration slip
or title),.
• The country or countries in which
you plan to travel.
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
Chevrolet
is not responsible under
the terms of the Chevrolet New
Vehicle Warranty or Emission
Control Systems Warranty.

Your car receives its power from
a mixture of gasoline and air. The
air
is taken in to the system through
the air cleaner
so it's important to
replace the air cleaner at required
intervals. A dirty air cleaner re­
duces engine efficiency.
Properly Tuned Engine
Overall tuning (a check on tim­
ing, 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
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
emission 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 and driveability.
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 cata­
lytic converter to
become ineffec­
tive as an emission control device.

1. Keep your engine properly tuned. Certain engine malfunctions, particularly involving the electrical, car­
buretion or ignition systems, may cause unusually high converter temperatures. Do not continue to operate
your vehicle if you detect engine misfire, noticeable loss
of performance, or other unusual operating condi­
tion s. A properly tuned engine will help avoid malfunctions that could damage the catalytic converter.
2. Do not park your car over combustible materials, such as grass or leaves, which can come into contact
with the hot exhau st system and cause such materials to ignite under certain wind and weather conditions.
3. Do not push or tow this vehicle to start. Under some conditions, this could damage the catalytic converter.
DISREGARD OF THESE WARNINGS COULD CAUSE DAMAGE TO THE CATALYTIC
CONVERTER,
TO THE VEHICLE, OR PROPERTY NEAR THE VEHICLE.
