8. Take it easy.
Rapid braking, punching the accelerator and other forms of forceful driving can cut fuel efficiency by as much as one-third at highway speeds and five percent in the city. Driving more carefully can save you up to $1 per gallon.
9. Carpool, if possible.
While this won’t work for everyone, if you can split the costs of gasoline with someone else, you’ll definitely save a bundle. Plus, if you share driving responsibilities, it will allow you to read, write or accomplish other work instead of always driving.
10. Lighten up.
Reducing the weight in your car by 100 pounds can increase your fuel efficiency by up to two percent, the EPA says, or up to $0.07 per gallon. Don’t haul anything unnecessary.
11. Don’t idle.
Idling wastes gas. The bigger the engine, the more gas wasted.
Consider going inside to order your lunch rather than waiting in a long drive-through line. Using cruise control and the overdrive gear at highway speeds will also help improve your gas mileage.
12. Get regular tune-ups.
A car that isn’t running well wastes gas. A tune-up and other repairs can improve your gas mileage by about four percent, or $0.15 per gallon, according to the EPA.
Fixing a serious problem can improve mileage by an enormous 40 percent. The repairs might be expensive, but at today’s gas prices, it will be cheaper in the long run to do the repairs.
13. Clean it up.
A clogged air filter can decrease your gas mileage by up to 10 percent, or $0.37 per gallon. And using the proper grade of motor oil can save one to two percent, or $0.04 to $0.07 per gallon.
14. Check your tires.
Properly inflated tires improve gas mileage by up to three percent.
15. Buy where it’s least expensive.
