Thanks Kevin
Bill,
I guess from my post one might assume that I think By-pass filters are a joke. Sorry, as this is not the case. I was simply trying to point out that a given oil analysis with a By-pass filter that has excellent wear results may be a bit skewed when it come to the real wear taking place in the engine. I think I have done this.
With that said, I think By-pass filters are excellent, and as soon as I figure out which one will suit my personal taste best, I may someday have one on my own truck, but then again maybe not. As you said, the key to oil analysis is trend analysis, and also determining if the oil is still suitable for use in an extended drain interval.
