The national average has increased 6.9 cents per gallon during the last month and stands 7.8 cents per gallon higher than this day one year ago.

“While the national average has seen little change in the last week, prices in the Great Lakes have skyrocketed. In many cities in that region, new all time record high prices have been set,” said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. “In areas that have featured skyrocketing gasoline prices amidst stable oil prices, refineries continue to be beset with shutdowns, maintenance, and other problems that have hampered production of gasoline and other products, leading to much higher prices. While these situations are difficult for motorists to digest, relief is on the way and will likely arrive in a few weeks,” DeHaan said.

GasBuddy operates MinnesotaGasPrices.com and over 250 similar websites that track gasoline prices at more than 140,000 gasoline stations in the United States and Canada.
