California drivers paid pump prices that have been as much as $1.50 higher than the rest of the nation since last summer.
So California state AG Harris has issued subpoenas to oil refiners as part of an investigation into unusually high gasoline prices in California during the last year.
During the Exxon Mobil Torrance outage in February 2015, California refiners reaped record net income, even as gasoline prices were falling elsewhere in the country. Beyond the Torrance outage, critics of the oil companies blamed manipulation of the gasoline market for exacerbating the price increase. 80 million gallons of gas was shipped to China in Sept 2015 http://justacarguy.blogspot.com/2015/09/todays-new-refineries-in-california.html
Questions include why an Exxon Mobil ship was not used to deliver gasoline to California as inventories depleted as the Torrance refinery’s production level dropped below 20%.
The Torrance refinery can account for 10% of the state’s refined-gasoline capacity, and 20% of the capacity in Southern California, but rarely does, as the annual shut downs to switch from summer to winter blend and back (no idea why that is necessary when the weather doesn't change in So Cal) and when that isn't causing a shut down, the irregular explosions and break downs, and scheduled maintenance seen to take it down from optimum operation once or twice a year.
