Recommended full synthetic oil

[Diesel_Pusher]

Full synthetic has many good things going for it.
However, the high price is generally amortized by increasing the drain interval....which...all things considered is not a good idea. We all know and respect Rawze's views, backed by a certain amount of experience, on that score.

Industry has some very good systems of oil filtration. These items are not found in the J.C. Whitney catalog...nor are they found in a truck stop.
There are two and only two that I've found helpful. I have used both. Each has its strong point.
My first post mentioned these two by name and were redacted.
I have to respect that but not necessarily agree with it.
Both have extensive track records of successful filtration.
I have never paid for an oil change and never intend to.
I have no financial interests in either.
I'd be glad to discuss this via PM if someone might be interested.
