Certified Oil on Main Street in Carrollton is my number one pick for gas. Your gas is pumped for you, and it is among the cheapest in town. The cigarettes are among the cheapest in town, too, if that helps anyone. Around $10 for 3 packs, and that's cheap nowadays. They also have propane, ice and free air. The parking lot is small, though, enough room for people to get gas and about 3 more cars.
