Randall Jeppesen reportingGas prices keep hurting all of us. But try constantly filling up more than 215,000 vehicles. That's what the U.S. Postal Service is facing.
Every time the price of gas goes up one penny, nationwide it cost the U.S. Postal Service an extra $8 million a year.
Ron Hubrich, with Salt Lake City's main post office says it's doing regular tune ups on Utah's post office vehicles to get the best fuel mileage possible.
"We have around 1,500 vehicles that go out on a daily basis," he said.
Mail carrier routes are under the microscope as well.
"[There are] evaluations nationwide on making each route a little more efficient," Hubrich said.
Nationwide, the post office spent $500 million more on transportation costs last year than it did the year before.
