I updated the UOA thread, but it became awash in the sea of other posts, so I thought that I would start a new one specifically about the topic at hand.
I recently ran M1EP for 17,475 miles and posted the UOA, but at the time Blackstone forgot to run the TAN on the oil. They did that and sent me the results and I have to admit, I am not overly excited about the TAN numbers or EP (at this point). AFE (in my engine) seems to work as well as if not better than EP. AFE had a TAN of 5.3 at 15,109 miles whereas EP had a TAN of 8.9 at 17,475 miles. Although the EP was ran for 2 months longer and 2,366 miles further, I do not believe there should be such a variance in the TAN numbers. The wear metal numbers are similar so the higher TAN did not affect wear--yet. I plan to cut this run of EP at 15K to see how it directly compares to AFE, but unless something changes, I may go back to AFE.
Thoughts? Comments?
