Bumped for comparison to jimbrewer's uoa. I believe that the universal averages were based on 5900 miles when DuckRyder sent his first sample, but don't hold me to it. I'm close, anyway.
 
From the first sample:

Quote:
Universal averages for this type of Ford engine are based on about 6,700 miles of oil use


I would caution a couple of things about comparisons to mine.


  • The hours may be a better comparator than miles, frequent high idle times for me.
  • This vehicle almost never has a short trip where it does not reach operating temperature.
 
Thanks DuckRyder. I was a little farther off than I thought. The idle hours don't show up in wear metals, as your iron wear rate is about the same in a ppm per 1k comparison to jimbrewer's. The TBN is reduced by the extra idle time, though.

Thanks for the extra effort/cost of running two different lab tests, too.
