Fuel Economy - Honda 1993 Civic Reference Owner's Manual

Fuel Economy

The condition of your car and your
driving habits are the two most
important things that affect the
fuel mileage you get.
Vehicle Condition
Always maintain your car accord-
ing to the maintenance schedule.
This will keep it in top operating
condition.
An important part of that mainte-
nance is the Periodic Checks
(see page 99 ). For example an
underinflated tire causes more
"rolling resistance," which uses
fuel. It also wears out faster, so
check the tire pressure at least
monthly. In winter, the build-up of
snow on your car's underside adds
weight and rolling resistance.
Frequent cleaning helps your fuel
mileage and reduces the chance of
corrosion.
Before Driving
Driving Habits
You can improve fuel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more fuel.
Always drive in the highest gear
practical for your speed and road
conditions. Gain the best fuel
economy by using the upshift
indicator, if equipped, to direct
your shifting during acceleration
(see page 32).
Depending on traffic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your car uses extra fuel. Use the
cruise control, when appropriate, to
increase fuel economy.
A cold engine uses more fuel than a
warm engine. It is not necessary to
"warm-up" a cold engine by letting
it idle for a long time. You can
drive away in about a minute, no
matter how cold it is outside. The
engine will warm up faster, and you
get better fuel economy. To cut
down on the number of "cold starts,"
try to combine several short trips
into one.
The air conditioning puts an extra
load on the engine which makes it
use more fuel. Turn off the A/C to
cut down on air conditioning use.
Use the flow-through ventilation
when the outside air temperature is
moderate.
