Want to save 20% or more on fuel costs? Follow these 10 simple tips from the Consumer Federation of America.

Check Your Air Filter

Straighten Up

Poor alignment not only causes tires to wear out more quickly, but also forces your engine to work harder, which can reduce fuel economy by as much as 10%.

Cost Savings: 28 cents per gallon.

Tune Up

A properly tuned engine can improve mileage by 4%.

Slow Down

For every 5 mph you reduce highway speed, you can reduce fuel consumption by 7%.

Cost Savings: 19 cents, by reducing speed from 70 mph to 65 mph.

(Don't) Give Your Foot a Brake

Lighten Up

For every 100 extra pounds carried around, your vehicle loses 1 to 2% in fuel efficiency.

Don't Be Idle
