Your F-150 has really been eating up the highway miles you've been putting on it, and there's a lot less wear than we found last time. The shorter oil run helped out some with that, but we don't think that deserves all of the credit for the improvements. This run was only ~1,300 miles shorter than your first sample, so your engine made less wear per-mile than before. The viscosity read in the 10W/30 range, but that didn't do any harm. That's what you're running now anyways. The trace of fuel is harmless. A TBN of
4.8 is strong.
I am thinking of switching to Rotella T6 5W40 for my next run, any thoughts or suggestions?
