1) When coming up to a red light or stop sign in the distance, take your foot off the gas and coast to the red light or stop sign. Dont accelerate or continue 'driving' to the eventual stop.
2) Accelerate slower. Car engines use more gas when the tachometer climbs high. Starting off slower from a standstill will keep your gas consumption down.
3) make sure your tires are filled properly. A common mistake is to look on the side of the tire for the proper psi. That's wrong. Look on the inside of the door. There's a sticker there that tells you what your tires need to be filled to. That sticker is apropriate for the car. The tires on your car might be OEM equipment on 20 different models of cars with different weights. The proper amount of tire tread on the road will give you optimal gas mileage.
4) Determine the most efficient speed for your vehicle. In reference to the above...do some testing and determine what speeds are the most efficient speeds for your car. Don't trust the little 'readout' in your car either. Actually fill your tank on the way to work, record your odometer, drive to work at an extremely constant speed, when you get to work, refill your tank. Take the difference in odometer readings and divide it by the amount of gas you needed to put in your tank when you get to work. try the same experiment at different speeds. Chances are, you will arrive at a number that is *not* 55mph, but a little bit higher.
5) lose weight. Yeah, this might not fly on this board...but being a fat ass can and will cause your car to have to cart around extra poundage it doesn't need to. Don't carpool with fatties or charge them extra for gas...
6) take the golf clubs out of the trunk. In the same spirit as #5, reduce excess weight in the car that you don't need. why pay to drive around golf clubs, a stroller, books or garbage....when you can store them at home for free?
Yes on all counts. I experimented with "Hypermiling" for a few weeks last year, and am giving it a 2nd shot. At the time, I tried as much as I could to use the techniques I felt were safe, and especially was surprised at how many places in my daily route I was able to coast for upwards of even a mile without losing much speed if any. We're just kinda used to thinking we are only going forward as long as our foot is on the gas pedal, and it's not true. Also, I might cut the engine if stuck at a red light for more than a minute. I did try some of the more extreme Hypermiling techniques such as also cutting off the engine when coasting long distances, but with power steering/brakes, I felt that was just foolish and dangerous. Overall at the end of the experiment, I was pulling about 3mpg more out of my vehicle than I ever had before, but at the time decided that wasn't enough of a benefit to sacrifice driving my car the way I like to, so I stopped. I'm giving it another shot now.
