Plan your trips. Keep lists of needs that will require a trip and try to accomplish multiple objectives with each. This will not increase your fuel mileage (the number of miles your car moves for each gallon of gas), but it will help you drive less (which, in turn, means you use less gas).
Lighten your load. Get the lightest car that will serve your needs. Weight is one of the biggest causes for loss of kinetic energy in non hybrid cars. If you're not shopping for cars, then take any extra weight off of the one you're already driving. If seats that you don't use can be removed, take them out. If you use your trunk as a storage space for heavy things, find another place for them. An extra 100 pounds increases fuel consumption by 1-2%. (Weight is most important in stop-and-go driving. In almost exclusively highway driving, it matters little: once the car is up to speed, it need only push air out of the way.) Don't remove things from the car that you need frequently; instead, make sure these are in the car and readily accessible because wasted trips to retrieve or replace them will be much worse than a little lower mileage.
When you fill up with gas, fill up halfway and try and keep your tank above one quarter full. If your fuel runs low,you could put stress on the fuel pump. 10 gallons adds 60 pounds of weight
Slow down. The faster you move, the harder your engine has to work to push through the wind. Speeding can reduce fuel efficiency by up to 33%. (Factors other than air resistance decrease fuel economy below about 60 MPH, so fuel economy is not a reason to go slower, but fuel economy decreases rapidly above that speed).
Use cruise control. In most situations, using your cruise control reduces fuel consumption by maintaining a constant speed.
Accelerate smoothly with moderate throttle. Engines are most efficient with moderately high air flow (throttle) and at revolutions per minute (RPM)s up to their power peak (for small to mid sized engines this is generally somewhere between 4k to 5k RPM). In a manual transmission car, practice 'short shifting', or shifting to higher gears as soon as you reach your desired speed by skipping intermediate gears. For example, accelerate to 40 mph using 1st gear and 2nd gear, then shift directly to 4th (skipping 3rd), or if your engine can maintain your speed, to 5th. (Be aware that if you have to floor the accelerator pedal in 5th to maintain your speed, you should be in 4th!).
Plan your route carefully. Take the route with the fewest stops and turns and least traffic. Take highways in preference to city streets when possible.
Avoid braking wherever possible. Braking wastes energy from fuel that you have already burned, and accelerating after braking consumes more fuel than driving at a constant speed. On city streets watch ahead and coast when you see a red light or traffic jam ahead.
