Very few folks recommend going past 7,500 miles on the 6.0 with any oil. The primary reason being the 100k engine warranty...Other reasons are the oil shearing effect of the diesel engine & fuel contamination. There are a few folks that say they are running up to 10,000 miles but also get the $20 oil analysis. I run the Mobil1 & change at 5,000 mile intervals.
