Meanwhile, a refinery fire in Venezuela over the weekend appeared to contribute to fluctuations in U.S. gasoline futures, although Hurricane Isaac's approach appeared to have a bigger effect.
Gasoline futures rose 7.7 cents, or 2.5 percent, to $3.155 Monday in New York, on concerns about supply disruptions from the storm and the closed Venezuelan refinery. Tuesday, U.S. gasoline futures fell 2.87 cents to $3.126 as traders waited to see how big an impact Isaac has on U.S. refineries, and as Venezuelan officials said the damaged Amuay refinery would restart in two days.
Benchmark oil rose 86 cents Tuesday to finish at $96.33 per barrel.
