Average retail gasoline prices nationally have increased 3.8 cents per gallon in the last week to $3.75 per gallon, according to gasoline price website GasBuddy.com.
The national average has increased 28.3 cents per gallon during the last month and stands 22.4 cents per gallon higher than it was one year ago.
"With a likely peak in gasoline prices still as much as two or more months away, the national average for a gallon of gasoline has already hit the bottom of the range that we projected back in January in our 2012 gasoline price forecast, which is quite concerning," GasBuddy.com senior petroleum analyst Patrick DeHaan said. "While the recent pace of price increases has slowed somewhat, the spotlight will now shift to refining facilities as they start and finish maintenance. Any unexpected problems arising from such may cause prices to resume a quick climb."
