You probably are passing a bit more unburned fuel past the rings with the higher delivery, I wouldn't worry too much about that. The 7.3's are pretty dirty engines from a particulate standpoint (especially iron) I'd look at running a better grade oil filter and/or a bypass system if you don't want to have to change your oil so often.
Blackstone Report ---Fuel Contamination
I have a 7.3 with 117,000 miles. To date never had a problem with this Truck. Did my first Blackstone report at 60,000 miles, all elements were below average except Iron (34). All reports since have been the same, the only thing above average is Iron. My last 2 back to back reports showed Fuel contamination with a below average flashpoint (400). The Fuel % average is <2.0 , mine checked 1.0. If I am reading this correctly how can I have Fuel contamination(low flashpoint) and be below average for Fuel %. 3 months ago I switched from a 55 hp chip to an Edge Evolution and shimmed the regulator (55psi to 68psi). Could these changes be causing this or do I really not have a problem. Oil change every 5300 w/ Rotella T 15-40. Sorry for the long post.
Thanks, Robbie
