Do clean cars improve gas mileage?

During times of rising gas prices, the question on everyone’s mind is, “How can I save money on gas?”

As it turns out, the answer is as easy as keeping your car clean, mainly because the answer IS keeping your car clean!

As written by Motor Biscuit in 2009, this theory was tested by the MythBusters on their episode “Dirty vs. Clean Car.” In this episode, Jamie Hyneman and Adam Savage tested the gas mileage of an older Ford Taurus. The duo ran tests both while the car was dirty and when it was glistening clean.

The original hypothesis was that the dirtier vehicle would be more aerodynamic, similar to how the dimples of a golf ball create lift and drag on the ball, which allows it to travel further.

However, what they found was that the dirty vehicle was much less fuel efficient, reaching only 24 miles per gallon (MPG), while the clean car got 26 mpg.

How to save gas with a better shine

As dirt and grime build up on your car over time, its rough surfaces cause the vehicle to become less aerodynamic, thus reducing speeds.

Cleaning your vehicle then makes the surfaces easier for air to flow over, allowing you to travel farther and vastly improve your fuel economy. So, no need to search for cars with better mpg if you’re already in love with your current vehicle.

Motor Biscuit also mentions that another way to improve gas mileage is by maintaining a wax coating on your vehicle. By filling in cracks and divots, the wax smooths the surface of your car, thus also making your ride more aerodynamic.

Thankfully, the Ceramic Body Wax provided through the WORKS wash package at Tommy’s Express is precisely what your car needs!

Besides its ability to provide a more aerodynamic ride, our wax also provides a protective layer that will prevent harmful UV rays and micro-abrasions from damaging or scratching the exterior of your vehicle. With your ride’s new shiny surface, you’ll look better, feel better, and you’ll be protecting your investment.

Don’t let surging gas prices prevent you from going out and living your life. Visit your nearest Tommy’s Express location and try our Ceramic Body Wax to have a smoother, slicker, safer, and speedier ride.
