I pick up my new 2005 F350 SC LB 4x4 DRW 6.0L 4.10 two weeks ago and the oil was always over the max on the stick. After 4 days of trying to find the the oil mark I couldn't take it any more. So I went out and picked up 16Qts of Rotella 15-40 and a new filter. I but the truck on level ground removed the dip stick and drained the oil.When the pan was done draining I drained the filter housing and replaced the filter. When the pan stopped draining I put the plug back in. I then put in 12Qts of oil and ran the truck for 3mins.and then truned the engine off. I than went in the house and made a cup of coffee and after 15mins went back out and picked up the dip stick off of my work bench and check the oil. It was at the min line. I now put in 1 and a 1/3 Qts. Let it set for 5mins and rechecked the oil and it was at 1/2 way between min and max. I did not add any more oil. I've checked it every day for the last 5 days and it's easy to see and always 1/2 way between min and max.
