Full Answer

  1. Take it easier on the pedals

    Avoid rapid acceleration and braking unless it is absolutely necessary. Moderate changes in speed yield fuel efficiency increases of 5 to 33 percent, depending on current habits. Keep your speed at or below 60 miles per hour to maximize efficiency; each five miles per hour above 60 leads to an average cost increase of about 24 cents per gallon as of 2014. Use cruise control when traveling on mostly flat highways to increase fuel efficiency by as much as 14 percent.

  2. Keep tires and wheels in shape

    Check tire pressure regularly. Maintain proper alignment for each wheel, as poor alignment makes tires drag rather than roll with minimum friction, resulting in a reduction in fuel mileage of up to 10 percent. Balance and rotate tires according to the instructions in your owner's manual to ensure even wear.

  3. Change travel routines

    Put gear and equipment in the car only when necessary, because every extra 100 pounds reduces fuel efficiency by 2 percent. Fill up the gas tank first thing in the morning or late at night, when lower temperatures make gas denser and result in more fuel for the dollar.
