[Updated, 1:49 p.m. Oct. 5: An earlier version of this story said the state's gasoline record was set during a run up of oil prices that eventually topped $1.47 a gallon.]
The average price for a gallon of regular gasoline in California jumped a whopping 17.1 cents overnight. That makes it almost certain that the state's motorists will see a new all-time record high for gas sometime this weekend.
Friday's average price for a gallon of unleaded regular in California is $4.486 a gallon, which is by far the highest in the nation. That's according to the AAA Fuel Gauge Report, which tracks prices from more than 100,000 retail outlets from around the nation.
On Thursday, California's average price was $4.315 a gallon. Analysts have blamed the sudden increase on a recent spate of refinery problems.
