Be a Better MPG Driver

About this Project

The Most Important Factor Impacting Your Car’s MPG is You

Jackrabbit starts, accelerating toward stop lights, going a little (sometimes a lot) over the speed limit — we all do it sometimes, and these actions take a real toll on gas mileage. It’s a fact: the faster, more aggressive you drive, the more fuel you burn. The Department of Energy estimates that aggressive driving can “lower your gas mileage by roughly 15% to 30% at highway speeds and 10% to 40% in stop-and-go traffic”.

On the other hand, cultivating mileage-minded driving habits can give your MPG a noticeable boost, which means you’ll spend less at the pump. Possibly much less.



Skeptical? Check out the video by the Oak Ridge National Laboratory.  They did side-by-side testing at their lab to determine how much aggressive driving could cost you in gas and MPG.

Drive Smart to Save Money

Not sure whether your driving counts as aggressive?  Check out for the best advice on improving your MPGs and driving smarter.


Let’s see. According to the Department of Energy, each 5 mph you drive over 50 mph is like paying an extra $0.20 per gallon for gas. That can add up quick!

For every extra 100 pounds of stuff in your car, your MPG is reduced by about 1%. Those rooftop cargo containers also hurt your fuel economy by impacting the aerodynamic drag of your vehicle. They reduce fuel economy by around “2% to 8% in city driving, 6% to 17% on the highway, and 10% to 25% at Interstate speeds (65 mph to 75 mph)”.

If you really want to reduce your MPGs, consider buying a hybrid or electric vehicle the next time you are car shopping. Talk to your car dealer and visit this website for the latest list of incentives.
