San Francisco Gasoline Advances to Week-High After Valero Upset

Spot gasoline in San Francisco strengthened for a third day to the highest level in a week as Valero Energy Corp.’s Northern California refinery worked to increase rates at a unit following an upset over the weekend.

Valero’s 170,000-barrel-a-day Benicia refinery was returning the fluid catalytic cracker to planned rates after a “brief outage” June 29, Bill Day, a spokesman at the company’s headquarters in San Antonio, said by e-mail today.

“No material impact to production is expected,” he said.

The same fuel in Los Angeles climbed 1 cent versus futures to a premium of 10 cents a gallon.

Exxon Mobil Corp.’s 150,000-barrel-a-day Torrance refinery in Southern California plans to flare gases from tomorrow through July 4, a notice to the South Coast Air Quality Management District shows. The flaring isn’t related to a breakdown, according to the filing.

Carbob in San Francisco gained 5 cents against the fuel in Los Angeles to a premium of 3 cents a gallon, its highest level since May 30.
