Oct. 12 (Bloomberg) -- Gulf Coast gasoline weakened on expectations that a government report tomorrow will show that supplies of the fuel were unchanged more than a month after the end of the summer driving demand season.
Gasoline inventories in the week ended Oct. 7 may have held steady at 213.7 million barrels, according to the median estimate of 15 analysts surveyed by Bloomberg News. The summer driving season ended on the U.S. Labor Day holiday Sept. 5.
The premium for conventional, 87-octane gasoline in the Gulf region weakened 1.5 cents to 1.3 cents a gallon versus futures traded on the New York Mercantile Exchange at 12:34 p.m., according to data compiled by Bloomberg. Prompt delivery fell 1.95 cents to $2.7561 a gallon.
Husky Energy Inc. returned an isocracker to service at the Lima refinery in Ohio after maintenance, Graham White, a company spokesman, said in an e-mail. The unit is approaching full rates, he said.
Regular gasoline in Chicago slipped 0.63 cent to a discount versus futures of 7.5 cents a gallon.
Crude throughput at the Husky plant was expected to be 130,000 to 135,000 barrels a day during the work, between 80 percent and 85 percent of capacity, Carla Yuill, a spokeswoman for the Calgary-based company, said Sept. 6 in an e-mail.
The Lima refinery has a capacity of 155,000 barrels a day, according to data compiled by Bloomberg. Isocrackers, also known as hydrocrackers, convert heavy oil into lighter fuels such as high-octane gasoline or high-grade fuel oil through the catalytic addition of hydrogen.
