I improve my gas mileage by 38%, without spending any money, or "converting" my car. It's the equivalent to saving almost $2 per gallon, and you can do it too.

The first step to improve my gas mileage is to figure out just what my gas mileage is to begin with. I do this with a gas mileage calculator, a simple method of dividing miles driven by number of gallons used. You can do this easily if your car has a "trip meter". There are also devices that will help you calculate your mpg.

Next, I look after all the "onboard" factors that improve my gas mileage. I make sure my air motor oil and filter is clean, that my tires are properly inflated, that I remove any unnecessary weight from my trunk and back seat. Just these steps alone will save me as much as another 15%.

Next, I find the lowest octane gas that my car can use. Just switching from 89 to 87 can save my $.40 per gallon, or another 10%.

But the most important thing I can do to improve my gas mileage is to adjust the way I drive. I drive slower, I avoid driving during rush-hour when there is a lot of stop-and-go traffic. I do my errands during off-peak hours, and I combine my errands into a single trip wherever possible.

With just these simple, no-cost steps, I can improve my gas mileage by more than 30%. I also spend time reading about other ways I can save money by changing the way I drive and how I plan my errands. Websites like Gas For Less Money help keep me updated on gas conservation and fuel economy. It's an ongoing battle against these crazy gas prices!
