Nov 3 (Reuters) - Grades were mixed on Monday, dealers said, with inland grades rising while coastal crudes slipped.

U.S. crude oil stockpiles were expected to have risen last week, while gasoline and distillate inventories likely fell, a preliminary Reuters poll showed on Monday.

Five analysts polled by Reuters ahead of weekly inventory data estimated on average that crude inventories rose by about 500,000 barrels in the week to October 31.

Meanwhile, the spread between West Texas Intermediate crude futures and global benchmark Brent widened, which typically makes U.S. grades more attractive to foreign buyers.

The discount WTCLc1-LCOc1 widened to as much as minus $4.19 a barrel, suggesting an open arbitrage window.
