Various factors influence fuel consumption:
engine wear. brakes
and tires, environmen­
tal impact.
T his chapter addresses some of these
points.
Your
warm up.
When the engine is idling, it takes a very
long time to warm
up. Moreover. during
warm-up, both engine wear and exhaust
gas emissions are very high. Therefore, be
ready to drive
off immediately after starting
the engine and avoid high engine speeds.
Avoid
Upshift as early as possible -do not drive at unnecessarily high engine speeds.
The highest fuel economy and the least di­
sturbance to the environment are attained
when you drive at l
ow engine speeds and in
the highest possible gear.
For example , fuel consumption is twice
as high in 2nd gear as it is in the highest gear.
Downshift only when the engine is no longer running smoothly.
Depending on the transmission you have.
you can normally drive in the highest gear at
25 to 37 mph
(40 to km
Avoid driving at high speed.
Fuel consumption, exhaust emissions and
engine noise increase disproportionately at
high speeds.
you drive at approximately
three quarters of top speed, fuel consump­
tion
be reduced by one half. Never drive
faster than the posted speed limit and wea­
ther condit ions permitting.
Drive as smoothly as possible and keep a lookout ahead.
Unnecessary accelerating and braking in­
crease fuel consumption and disturb the en­
vironment.
Switch off your engine if you are caught in a traffic jam. This sa­
ves fuel and reduces emissions.
The
Heavy traffic, especially in large cities
w ith many traffic lights.
Stop-and-go driving, especially short di­
stances so that the engine never warms up as it should.
Driving in heavy, slow moving traffic in low gear so that the engine speed is relati­
vely high when compared to the distance
driven.
Plan your trips ahead of time. Organize your trips to include several errands and to avoid heavy traffic.
course. there are some conditions that affect fuel consumption that you can't
control.
For example, fuel consumption increases in
the wint er or under difficult conditions
(bad roads. towing a trailer. etc.).

lire service life
The service of your tires depends for the
most part on the

control.
Low tire pressures increase fuel
consumption which is
tal to the environment.
