KNOXVILLE, Tenn. (WVLT) - While the gas supply is low in the southeast due to the cybersecurity hack on the Colonial Pipeline, a Knoxville mechanic says there are things drivers can do to make their cars run more fuel efficient rather than panic buying gasoline.

Cory Beilharz, owner of Christian Brothers Automotive, says most newer cars are already as fuel efficient as they can be most of the time. But, he adds there are still some tricks to make your gas stretch to avoid the long lines at pumps as much as possible in the coming weeks.

Beilharz said one thing to keep an eye on is your tire pressure.

“The single biggest factor in fuel mileage to make it the best as possible is the air in your tires,” Beilharz said. “The recommended tire pressure you want to at least be at that. But if you look on the sidewall of your tire there’s maximum pressure and you can air it up to that to get maximum mileage.”

Aside from tire pressure, Beilharz said drivers should also be aware of the benefits to having the windows down versus using the air conditioning.

”If you’re under 45 miles per hour you’re going to be fine rolling your windows down. If you’re over 45 miles per hour it might be better to use your air conditioning for better gas mileage,” he said.

Beilharz also shared one secret he said some truck owners might not be hipped to: a tool box, ”the aerodynamics of having a toolbox right behind your back window actually helps a lot more.”
