FuelEconomy.gov is a website set up by the federal government. You can get the gas mileage of virtually any vehicle you may look at buying here in the U.S. You can put vehicles’ EPA ratings side-by-side to compare which one has better fuel economy. It’s easy to use and provide tons of useful information.
Keep in mind that beginning with the 2008 model year, the Environmental Protection Agency (EPA) changed how they calculate MPG for all vehicles. They now calculate the rating using different criteria. What you need to know is that these changes effectively reduced the fuel economy rating for virtually every car, truck, and SUV. The idea was to make the MPG closer to what drivers actually get.
If you are trying to compare one make or model to another, be sure that you compare "old" rating to "old" or "new" to "new." Otherwise you won't be comparing them in a fair manner. This is particularly important if you are looking to purchase a pre-owned vehicle and comparing the gas mileage of one vehicle to another.
If the vehicle you are selling is economical to operate, consider putting the fuel economy rating in your online ad. Be sure to list the city, highway, and combined MPG rating. This will not only make your ad stand out from the hundreds of others online, but it’s actually useful information for potential buyers.
