Newly posted data from California oil refiners shows that record price spikes at the pump have translated to a record high return to the oil companies of $1.17 per gallon in May of 2015. The average amount that a refiner receives for a gallon of gasoline has been just 46 cents since 1999, according to the California Energy Commission (CEC), but recently updated data on the CEC website shows that in May refiners took home more per gallon than ever before. Consumer Watchdog had urged the CEC to update the data, which had not been posted since August.
