Gas Mileage

Do you ever wonder why gas mileage never seems to get better despite all of the technology improvements being made in automobiles?  One reason is that the U.S. Environmental Protection Agency (EPA) sometimes changes the way MPG estimates are determined to better reflect actual driving conditions and driver behavior.

Starting in the model year 2008, estimates reflect faster acceleration / speed, air conditioner use and colder outside temperature.  The estimates will generally result in lower MPG for most car models by typically 1 - 5 MPG.

The EPA ratings are useful for comparing one car model versus another but will not predict the actual MPG you will get.  There are many real-life factors including vehicle condition and maintenance, where and how you drive, fuel variations and other factors that affect actual performance.

You can maximize your fuel efficiency by keeping your car well maintained and drive at the speed limit.  Gas mileage generally decreases rapidly above 60 miles per hour.
