Marathon Oil has that refit to do on their refinery in Long Beach after that "mysterious explosion" last week. We won't see any decline in gas prices. It must be part of the operator's manual on California refineries.
Step #1--- When a portion of the refinery needs a refit, schedule a "mysterious fire/explosion".
Step #2--- Call the insurance company and let them pay for the repairs with modifications.
Step #3--- Raise gas prices
Step #4--- Reap the profits.
