Fun fact about the cost of gasoline in CA from the US Energy Information Agency...

"California gasoline prices are generally higher and more variable than prices in other states because relatively few refineries produce California's unique blend of gasoline. California's reformulated gasoline program is more stringent than the federal government's program. California's tax on gasoline is also higher than most states' gasoline tax.

California refineries need to run at near full capacity to meet the state's gasoline demand. If more than one of its refineries experiences operating problems at the same time, California's gasoline prices can increase substantially. Even when supplies are available from other West Coast refineries, U.S. Gulf Coast refineries, or from foreign refineries, they can take a relatively long time to arrive in California."

and with regard to local price differences...

"Prices at gasoline stations are often highest in locations with fewer gasoline stations. Even stations located close together may have different traffic patterns, rent, and sources of supply that influence pricing."
