Friday Fuel Economy: mpg Math

| 7/13/2007 12:00:00 AM

The first step to improving your car or truck's fuel economy is to know how many miles per gallon it really gets. Calculating mpg is easy, even if you hate math. Plus, monitoring your fuel economy and becoming more aware of what influences it is one of the simplest ways you can make a difference for the environment and your wallet.

Here's how to do the math. It's easier than you might think.  

1. Fill up your tank.

2. Reset your trip meter to zero.

3. Get gas when you need it.

4. Record the number of gallons it took to fill your tank and the number of miles on your trip meter. You could write these numbers down in a small notebook, or perhaps an easier place is the gas receipt. Usually these already include the number of gallons you bought.

I love the challenge your articles have laid down to all of us. I recently purchased a '90 Civic Si for $2200 to become my daily driver. I parked my '04 GMC Sierra extended cab truck that got 17 mpg. My "new" civic gets 30 mpg around town, and has gotten 34.3 mpg on the highway. I could probably get much better by changing my style, but the bottom line is that I use 25 gallons less gas every month. We use it as much as possible on weekends, and other trips around town. Thanks again for the challenge to our conventional way of thinking.
