A tire's rolling resistance can add
or detract another 1 or 2 mpg. In our tire ratings, look for high-rated tires
with low rolling resistance. They generally won't cost more, and replacing a
worn tire could save you more than $100 a year in fuel.
Avoid idling for long periods
Think of it this way: When you're
idling, your car is getting zero miles per gallon. When we let a Buick Lucerne,
with a V8, idle for 10 minutes while warming up, it burned about an eighth of a
gallon of gas. A smaller engine would probably burn less, but idling still adds
up over time. As a rule, turn off your engine if you expect to sit for more than
about 30 seconds. An engine warms up faster as it's driven anyway.
