SUBSCRIBE to the Fact of the Week
Most of the nation has enjoyed average gasoline prices below $3.00 per gallon since the beginning of 2015. California and the rest of the West Coast, however, have experienced higher gasoline prices than the rest of the nation. Although gasoline price changes are caused by a myriad of factors, the likely cause for the high West Coast prices is an explosion and fire at a California refinery in February of 2015. The sudden decrease in refinery output resulted in tight supplies on the West Coast. In addition, few refineries outside of California are equipped to produce the gasoline formulation that can be sold in California, which is different than the rest of the nation due to State regulations.
