Bob,
please read this post and let it sink in before firing back. I will do the same for you too.
I have reported very good oil analysis on oil that had about 8000 miles on it. It was Amsoil and I had the daul by-pass filters on board. I feel that the by-pass filters can remove the evidence of internal engine wear and therfor not show what really goes on inside after the lond drain cycles. That being said, I still feel that by-pass filters are a good thing if the oil is changed on a timetable that meets the OEM's guidelines. They remove more stuff and therfor are better for that application. I do feel that the wear particles can be removed and give a better than actually test result. OEM's know it too. Maybe oil drain cycles are good for some applications, but not for overfueled engines and not for the super extended oil drain cycles some do. I see guys with a 100,000 miles on their oil. Others see this and do the same thing hoping to never pull the drain plug again. I did. Some guys have more soot production from extra fueling. Extended drains are not for everyone.
