September heating oil traded higher during the early morning hours but continues to face a weak and uncertain outside market tone. September heating oil came under pressure during Wednesday's session from a larger than expected distillate inventory build. EIA distillate stocks saw an increase of 3.385 million barrels. Distillate stocks stand at 15.668 million barrels below last year, but are 7.898 million above the five year average. Distillate imports came in at 161,000 barrels per day compared to 92,000 barrels the previous week. Average total distillate demand for the past four weeks slipped 3.49% compared to last year. EIA heating oil stocks rose 549,000 barrels.
