The price at the pump continues to climb.
AAA spokesman Sean Comey says California refineries are in the process of switching over from their winter formula to their summer blend of gas designed for use in warmer weather.
The decline in production that occurs during the switch-over pushes the price of gas upward. Comey says most of the fuel used by motorists in the Mother Lode comes from refineries in California and Alaska.
