Very impressive analysis and I truly believe -- the more feedback/results we get from HP Lubricants products users -- will yield the same results overall.

Why automatically stop at 20,000 mi?
Sample every 5,000 mi and change the filter as required (20,000 mi?). Change the oil when the analysis says it's time.

I don't have a lot of experience with gasoline extended drains but I do with diesel. At this point it looks like that oil will only be getting warmed up at 20,000 mi.

I think that's what we will do, when the UOA shows the oil is condemned or close to being condemned, then we'll change.
