Gasoline on the U.S. Gulf Coast fell to a six-month low with refinery maintenance nearing an end and supplies of the fuel at a seasonal high.
Conventional, 87-octane gasoline in the Gulf dropped for the seventh day in a row, declining 2.25 cents to 20.75 cents a gallon below futures on the New York Mercantile Exchange at 1:46 p.m., the lowest level since April 5, according to data compiled by Bloomberg. The conventional CBOB grade fell 1 cent to 21.5 cents below futures.

Differentials weakened as the peak of fall maintenance neared, which may increase production, adding to supplies in the region.
