Ohio drivers can expect to pay a little bit more at the pump this week. The average price for a gallon of regular gas is $3.45 in Monday’s survey from Auto Club AAA. That’s up 9 cents from a week ago. A year ago the average was $3.70. Nationally, the average price for regular gas is about $3.47, another seven cents higher than last week. Analysts say the higher prices are mostly due to rising crude oil prices, spurred upward by better-than-expected global economic concerns and simmering tensions in the Middle East. U.S. oil supplies swelled in June to 22-year highs but have declined since then.
