Cruising Through Summer on One Tank of Gas

Brancaccio is keeping track of her progress through a blog dedicated to her summer goal, appropriately titled "One Tank or Bust."

She uses her blog as a tool to share with readers her ways to increase the miles per gallon on their vehicles such as maintaining the pressure in the tires. When the tires have more air, it takes less energy for them to move the car, which ultimately saves the driver gas.

She said she would encourage others to follow her lead.

"People think it's a lot harder than it is to save gas," she said. "Small changes will save a lot in the long run."

Unfortunately, the college junior has not eliminated maintenance expenses on her car by driving less often. She has been able to postpone her next visit for an oil change, but she has had to purchase a new battery, costing her about $100.

"I left my lights on," said Brancaccio.

Hot summer days in the upper 90s and even triple digits have tempted her to give in, but she has remained faithful to her goal. Even though the price of gas has decreased 30 cents to $4 since she has been home, she refuses to fill up and drive.

Brancaccio has driven more than 200 miles and has 34 days left of her challenge.

She expects to meet her goal by the end of the summer but said, "If it doesn't work, it will be OK."
