California drivers saw a major spike in the price of gas over the weekend.

Prices jumped an average of 16 cents to a record $4.65 a gallon, becoming the most expensive fuel in the nation.

Some California stations are even charging more than $5 a gallon.

Experts blame last month's fire at a gas refinery and pipeline problems in Southern California. But drivers aren't buying that excuse.

"I think it is just outrageous," California driver Karen Smith told a local news reporter as she drove up to fill her gas tank. "And I am not sure what the reason is for that. I don't believe what's being reported."

Driver Sandy Christiansen told a television station, "It is just a matter of we are going to soak you a little bit more. They don't care."

California Gov. Jerry Brown has ordered the state's smog regulators to allow a cheaper winter blend of gasoline to be produced a month early.
