Hey everyone this is my first attempt at posting a UOA so sorry if it doesn't come out quite right. If anyone knows how to post a PDF please let me know. I have three other reports but I'm crunched for time and can't post those yet, but here are the results of the most recent. Comments concerns, are very welcome. Thanks in advance. Oh yeah I used an Amsoil EAO88 Oil filter and this was done by Blackstone thanks again

Make/ Model: 6.0 Powerstroke/Diesel
Oil Type & Grade: Amsoil 15w40
Oil Use Interval: 9497 Miles

ERIC: You certainly got the most out of this fill of 15W/40 by going nearly 10,000 miles on it. Your engine didn't mind and for an oil run this long, wear looks great! Only a slightly low viscosity kept this from being a perfect report. It was just slightly low and isn't a problem. No fuel, coolant, or moisture was found and your air and oil filters are working well, too. The TBN read 6.2 so you had plenty of active additive remaining. 1.0 is low. Had you wanted to run this oil longer we think you easily could have done so. Try 11,000 miles on the next fill. Nice wearing engine.

No Make up oil at all, and when I checked the dipstick just before I changed it, there was no noticeable change in the level. I am going to try to go 15,000 this time. OBTW, large car man, I beleive that this is a 25000 mile oil.
 
It's nice to see someone really use a premium synthetic and filtration for what they're intended for: extended drain intervals.

Very nice report.
 
Looks great...only thing that seems out of place is the: CST Vis @100 C 12.17, but that is indicative of the engine.
Nice.
