Presuming your questions were directed at me ...
I never said that. You may have read into my answers what you wanted to hear, or I didn't do a good job of explaining.
I'm saying two things:
1) type of most BITOG conversations, this thread is nearly boundless because there's enough latitude to say anything can succeed and anything can fail. Open ended questions deserve and get open ended answers.
2) I have proven to myself that in my fleet, given my operational patterns, in my environment, syns did zilch but waste my money. I have run 10k mile and 15k mile UOAs and seen no statistical difference in wear rates in my applications.
I've never, ever said syns were a bad idea; they can be great products when used in the right circumstances. I have repeatedly said, and will continue to espouse, that people here waste money because they change oils far too often, regardless of what base stock is used. They have no concept of wear rates or condemnation limits based on true mechanical criteria. They just "feel" their way through an O/FCI.
