LOS ANGELES -- It's a record, though just barely. The price of gasoline has hit an all-time average high in California of $4.6140 a gallon, fueled by a reduced supply and a volatile market.

AAA spokesman Michael Green says Saturday's price set the record by less than a tenth of a penny.

The previous high was $4.6096 on June 19, 2008.

Prices throughout the state are expected to increase for several more days before levelling off, after a temporary reduction in supply triggered a price spike.

AAA's Daily Fuel Gauge report released Saturday said the average price for a gallon of regular unleaded across California rose 12 cents from its Friday mark of about $4.49.

The Golden State has leapfrogged Hawaii as the state with the most expensive fuel.
