This is another problem with oil analysis again. The lab may have really muffed this report and recommendation to this fella.
We are trusting the testing labs and here is some evidence that they are wrong or may be wrong. I have only read a few oil analysis reports in my life and my qualifications to do so are not there. Even so, I can see that a mistake was made and the oil was toasted out of spec.
Generally when I need a problem solved I turn to professionals.
Tax problems I use a CPA. Legal issues I use an attorney.
Tribologist are the ones to turn to for oil troubles or advice.
People turn to me for calculating clean agent amounts for data rooms holding millions of dollars worth of computers or space and nuclear facilties. Most of us rely daily on professional opinions to get stuff done. A Tribologist was asked what he thought about the analysis and he stated the oil was toasted.
Therefor I see the value in his read of it. He does not sell oil to anyone. He actually analyzes oil for a living at the present time.
He recommends the guy stop extended drains and get the stuff changed more often.
As I stated above I have little oil analysis experience , but I have learned that water from condensation is handled by the additive package for the most part. I also see that a guy was using an oil of the wrong viscosity for his truck. Why is he doing this? Was he told like jsimpson was to do it? Did you tell him this? Just wondering why two of the handful of guys we have talked about were both using or were told to use an oil of the wrong viscosity.
Oh, Im guessing he did not have a by-pass filter that removed water either.

Could he not just use a by-pass filter and have his problem solved?
