Los Angeles gasoline fell for a second day after the California Energy Commission said inventories jumped 10 percent last week and Chevron Corp.’s El Segundo refinery was said to start a coker compressor.

California-blend gasoline, or Carbob, supplies rose to 5.32 million barrels in the week ended July 20, up from 4.83 million a week earlier, the state Energy Commission said in an e-mailed report. Carbob production also increased 6.2 percent to 6.55 million barrels, the state said.

Chevron’s 279,000-barrel-a-day El Segundo refinery, the largest in the state, started a compressor at the coker unit after a failure today, a person familiar with operations at the plant said. The equipment tripped offline briefly, said the person, who asked not to be identified because the information isn’t public.
