Myth: Gas station owners and operators are making a killing at the gas pump. Answer: False. Average Joe Gas Station Owner makes more money selling snacks, sandwiches and soft drinks than he does selling a gallon of gas. Profit margins in 2011 were typically 3 to 5 cents per gallon -- and the average break-even on fuel sales is about 14 cents per gallon, according to the National Association of Convenience Stores, whose members sell the bulk of gasoline in the United States.
