Useful Site –

Considering a new or used car purchase?  Do you know that fuel economy is a major component of overall cost of car ownership?

The US Department of Energy and the EPA have a great site that helps you compare various model used and new cars for fuel economy.  I am really excited to find the “Fuel Economics” section which includes:

  • Cost to drive 25 miles
  • Fuel to drive 25 miles
  • Cost to fill-up
  • Miles on a Tank
  • Tank Size
  • Annual Fuel Costs (and they list their assumptions)

To compare vehicles side by side from the main site, click on “Find a Car” in the upper left.

I really appreciate that they include user reported fuel economy telling how many data points are included and if you don’t have a typical driving practice of 55% city driving, 45% highway driving totalling 15,000 miles per year, you can even customize it based on your driving needs.

This has been really helpful in guiding my mom in deciding about her car replacement.  She drives a lot for work and knowing that she could save nearly $2,000 per year in fuel costs getting a Prius instead of a RAV4 will help her when deciding on similarly priced used vehicles.  She drives about 30,000 miles per year for work.

So if you are in the market for a “new to you car” or just curious how your MPG compares to others with the same car, go check out and find out.

Happy Greening!
