Oct 7 (Reuters) - Domestic grades broadly fell on Tuesday, dealers said, after crude inventories rose.
U.S. crude stocks rose while gasoline and distillate inventories fell last week, market sources said, citing American Petroleum Institute figures on Tuesday.
Crude stocks rose by 2.78 million barrels in the week ended October 3, the sources said on condition of anonymity.
Gasoline inventories fell by 1.25 million barrels, while distillate inventories fell by 1.82 million barrels from last week, the sources said.
Meanwhile the spread between West Texas Intermediate crude futures and global benchmark Brent widened slightly, which typically makes U.S. grades more attractive to foreign buyers.
The discount WTCLc1-LCOc1 widened to as much as minus $4.16 a barrel. A discount of around $4 suggests an open arbitrage window.
