The Tedeschi station (at Commercial and Bradford streets) sells a gallon of regular gasoline for $2.31, with 6¢ Tuesdays, where the pump price is automatically discounted by 6¢ at the pump, if you gas up on a Tuesday.
At the Gulf station, across the street, the current price is $2.46 for a gallon of regular, every day of the week. There is no significant difference in the quality of the gas sold by small independent stations compared to that sold by brand name refiners, since federal regulations govern octane and cleaning additives used in all gasoline sold in the US, though various major brands might include extra additives of their own. Any distinction in performance, though, would be just the tiniest difference in gas mileage, so bigger does not mean better. You may even choose to pay a higher price in order to support a small, independent gas station rather than a corporate giant.
Cumberland Farms, on Shank Painter Road, currently gets $2.37 per gallon, which will be discounted at the pump by 10¢ per gallon if you pay with their SmartPay card, which automatically makes a withdrawal from your checking account, once you set it up.
