Oil up on expected U.S. oil stock drawdown, but China gloom tempers gain

Oil prices were up in early trade on Tuesday ahead of data later expected to show a draw in U.S. crude oil and gasoline inventories, though persistent concerns over a slowdown in China's economy limited the upside. Brent crude was up 10 cents at $84.56 a barrel and U.S. West Texas Intermediate crude was trading 9 cents higher at $80.81 a barrel at 0101 GMT. U.S. crude oil and gasoline inventories were expected to have fallen last week, a preliminary Reuters poll showed, as the American Petroleum Institute industry group is due to release data later on Tuesday.
