Okay. Gas prices are crazy and this type of crazy probably isn't going away. There are many cars now that get good mileage, but if you are stuck with a gas guzzler then here are some things you can do to improve your fuel efficiency:

Keep your vehicle well maintained

A car in poor running condition will use more gas than one that has been tuned up. A dirty air filter can reduce gas mileage up to 20% and spark plugs in poor condition can reduce gas mileage up to 12%.

Keep tires properly inflated

Underinflated tires aren’t just dangerous — they devour fuel economy by as much as 25%!  Overinflated tires aren’t efficient, either. Also keep your tires balanced and in alignment.

Alter your commute time

If possible, schedule your trips and errands for times when traffic is lighter. If your company allows it, try coming in earlier or later in order to avoid rush hour.

Optimize your travel

Consolidate trips: If you know you have to buy groceries, take your clothes to the dry cleaner at the same time, and then drop little Johnny at soccer practice. Combine multiple trips into one.

Lighten your load

Carry only the bare neccessities — don’t haul things in your trunk. For every extra 250 pounds your engine hauls, the car loses about one mile per gallon in fuel economy.

Reduce drag

About half of your vehicle’s energy is expended overcoming air resistance. (The other half is expended in acceleration.) Reduce your car’s workload — remove anything that might cause drag: luggage racks, bike racks, ski racks, etc,

Drive at a constant moderate speed

Edmunds.com found that the best way to improve fuel efficiency was to accelerate slowly and to brake over a longer distance. Aside from purchasing a new vehicle, this is the single most effective step you can take to reduce your costs. According to fueleconomy.gov: “As a rule of thumb, you can assume that each 5 mph you drive over 60 mph is like paying an additional $0.20 per gallon for gas.”

Don’t idle

Turn off your engine if you’ll be idling for more than thirty seconds. Starting your vehicle does use a burst of fuel, but not as much as allowing the engine to idle too long.

Anticipate stop signs and lights

Plan ahead. The less you have to stop, the better your gas mileage. Make it a game to catch all of the green lights. Laugh at the other guy as he sprints from red to red.

Keep your cool

Most people claim that it makes more sense to use air conditioning on the highway, and to roll down the windows in city traffic. It’s commonly claimed that either method is going to reduce your fuel economy by about 10%. But according to research performed by found, there’s no real difference between driving with the windows down or using the air conditioner. Consumer Reports obtained similar results:

Drive less!!!

Walk. Ride your bike. Take public transit. Carpool. Combine errands. It’s obvious, but easy to forget: the less you drive, the less you’ll spend on gas.
