Analysts said that it would be days, if not a week or two, before Hurricane Sandy's impact on fuel prices in the Eastern U.S. can be assessed.
Today, the average cost of a gallon of regular gasoline was up by only the smallest amounts overnight in some states, while others actually saw price declines.
In New York, for example, the average cost of a gallon of regular gasoline was up just 0.3 cents overnight, to $3.931. That was still 7.9 cents a gallon below the week-ago price.
Much will depend on how quickly refineries along the Delaware River can return to service.
One other critical facility -- Phillips 66's Bayway refinery in Linden, N.J. -- sustained a power failure and some flooding.
Bayway has the capacity to produce of 240,000 barrels of fuel a day. It was shut down Monday in advance of the storm's arrival.
