"This week, Marathon announced that it will not reopen its Martinez refinery for the rest of 2020," said Jeffrey Spring, the Automobile Club of Southern California's corporate communications manager.

"While that primarily affects Northern California, it reduces supply options for Southern California as well and refineries have been buying excess supply on the spot market, pushing overall prices higher."
