Sept 23 (Reuters) - Physically traded domestic crude grades were mixed on Tuesday, dealers said, on the first full day of the volatile roll trading period.

Meanwhile, U.S. crude and gasoline stocks fell, while distillate stocks rose last week, market sources said, citing American Petroleum Institute figures on Tuesday.
