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.
