The national average has increased 9.1 cents per gallon during the last month and stands 9.3 cents per gallon higher than this day one year ago.

"The only thing I remain sure of with gasoline prices is that things will remain quite volatile the next four to six weeks," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. "Spot prices, a leading factor in retail gasoline prices, continues to swing wildly from region to region. Last week we saw a refinery fire on the West Coast drive up spot prices nearly instantaneously, an event that could occur in virtually any area. It's these events, the unforeseeable reaction, that gives me reason to say that prices may continue to swing upward and downward," DeHaan said.
