A poorly tuned engine
can increase fuel consumption by up to 50%.
Driving at 55 miles per
hour rather than 65 can reduce fuel consumption by 10%.
Under inflated tires
can increase fuel consumption by 5%.
A loaded roof rack will
increase fuel consumption by as much as 5% in highway driving.
Even an empty roof rack
can increase consumption by 1%. If the carrier is not attached
to the vehicle, remove it when not in use.
Avoid "Jack Rabbit" starts.
Not only do they increase fuel consumption, but are hard
on your tires. Anticipating stops and avoiding abrupt stops
will decrease fuel consumption and increase the life of
your brakes and tires.
Avoid unnecessary steering
wheel movement since each sideways movement of the tire
causes fuel-consuming drag.
