April 15 (Reuters) - Grades pulled in different directions on Tuesday, dealers said, after crude stocks rose but fuel inventories slipped.
Mars Sour WTC-MRS rose 20 cents to a midpoint of a $1.50 premium to U.S. crude futures CLc1, its highest since March 13, according to data from LSEG.
Crude stocks rose by 2.4 million barrels in the week ended April 11, market sources said on condition of anonymity, citing American Petroleum Institute figures. Gasoline inventories fell by 3 million barrels and distillate stocks fell by 3.2 million barrels, they said.
Meanwhile, pipeline operator South Bow SOBO.TO said on Monday it was keeping an eye on inclement weather before proceeding with a planned controlled restart of its Keystone oil pipeline system.
Some U.S. refiners, especially in the Midwest, rely heavily on the type of oil produced in Canada and delivered by Keystone.
