If a UOA shows that it's a waste of money I'll happily agree with you. But until then, the jury's out.
What would the UOA show that would distinguish it either way?
We've been on this site about the same amount of time and I think we both know the answer - let's just keep it simple and go with low wear numbers (arguably doable with other oils), TBN retention, minimal shearing or thickening, and perhaps an extended interval because of all those things - you know, all the things that true synthetics are known for.
I'd like to know what you'd need to see in a UOA to show it would be a waste of money? Yes there are less expensive oils to be had. 9000 is around $5-6 a quart depending on how you get it and what discount is offered.
