Why gasoline prices are rising while oil isn’t

Last summer when oil traded at a record high near $79 a barrel, gas at the pump went for about $3.03 a gallon. Today, crude’s about $62.50 a barrel and a gallon of regular unleaded costs $3.10

Doesn’t seem right, does it? The price of a barrel of crude ought to be a better benchmark for what you pay at the gas pump.
