How to Compare the Best MPG

The MPG of motor vehicles refers to the miles driven per gallon of fuel consumed. The more miles per gallon a motor vehicle has, the more efficient it is and the cheaper it will be to fuel and operate. The United States Environmental Protection Agency has regulations in place requiring vehicle companies to provide consumers with accurate MPG estimates for different models. These regulations make it easy for you to compare the best MPG.

Instructions
1. Get familiar with the Fuel Economy and Environmental Comparison sticker that is required to be on all new vehicles. The MPG for the vehicle is either located across the bottom or on the left hand side.

2. Write down the MPG for both city and highway driving. These figures might have a difference of a few miles or up to 10 miles, depending on the vehicle.

3. Find out the MPG for used vehicles by using the government resource FuelEconomy.gov. From this resource, you can choose the year, make and model and find out the MPG is seconds.

4. Write down the MPG for city and highway driving for the used vehicles you're comparing, as well.

5. Look at the differences in MPG on all the vehicles you looked up. Compare first the city driving MPG and then the highway driving MPG to get a better idea of how fuel efficient each vehicle is.
