martin_wExplorerJun 03, 2013gm 8.1 engineI have 2006 fleetwood flair with 6000 mi need to add oil about every 900mi . I see no leak on the ground or gray or black smoke. Wayne
okgcExplorerJun 03, 2013With only 6000 miles, How often has the oil been changed? Should be changed every 12 months regardless of miles. With your usage rate at 900 miles it would be due for an oil change not just adding a quart. Engine is probably not even broke in yet. Needs to be driven.
