NEW YORK — Bill Moore was as surprised as his customers when a gallon at his Steubenville, Ohio, gas station shot up 16 cents Tuesday. But he wasn’t surprised by the reaction.

“They’re irate. They’re complaining bad,” said Moore, the manager of the Lincoln Avenue Valero. “They want to know ‘What made it go up this time?’ I don’t know what to tell them. It’s going up for me as well.”

The reason for the spike was something not apparent to drivers and station operators on a sunny, 78-degree day in Ohio — Hurricane Isaac, battering the Gulf Coast more than 1,000 miles away. Preparations for the storm meant oil platforms and pipelines in the Gulf region were shut, cutting off the normal flow of oil to refineries in the Midwest.

A gallon of regular climbed to $3.95 a gallon from $3.79 at Moore’s station.

That scenario was common throughout Ohio. AAA‘s state-by-state estimate of gas prices Wednesday showed the state had the biggest one-day jump in the nation — a 13.9 cent increase to $3.878 a gallon. Neighboring Great Lakes states suffered similar spikes — a 13.2 cent rise in Indiana and a 12 cent rise in Michigan. By comparison, Gulf states’ gas prices were up about 4 or 5 cents, while the national average gas price rose 4.8 cents.

Moore says his customers are cutting back on their purchases, buying only a few gallons instead of filling up. That’s probably a pretty good strategy, since prices are expected to retreat quickly.

Fred Rozell, retail pricing director for Oil Price Information Service, which tracks prices for AAA, said market conditions in the Midwest traditionally make it one of the more volatile regions of the country for gas prices.

“They tend to really move whenever there’s an event,” he said. “It’s not uncommon to see prices in the Great Lakes states jump 20 cents or fall 20 cents in a day.”

Rozell expects prices to return to pre-storm levels by the end of this week, once oil starts flowing through the pipelines again. Next month, prices should fall further when refineries no longer have to make more expensive summer blends of gas. By the end of September, he expects the national average will be under $3.50 a gallon, down from $3.804 Wednesday.

But right now, gas is in short supply — and prices high — in the Midwest.

Habib Shah, director of marketing for Ohio Petroleum, trade group for independent station operators, said some of his members can’t even get the gas they need and have had to shut temporarily. Others are paying 20 cents more per gallon.

“They were having problems,” he said. “Especially if they’re in competition with the big chains, they’re having a tough time.”
