In my opinion, and I may be wrong, the UOA is really what counts. I know all the manufacturers say "theirs is the best" - "the lowest wear scars" - "extended drains" etc., etc., etc., but until a person tests it via UOA, it's all advertising that may or may not be true.
It's not what is on the outside of the bottle, but what it contains, and how it works in the engine you put it in.
How can anyone truly know how effective the oil is working until you sample it out, test it, review the results?
I am waiting for my results from Blackstone, hopefully this week, on 2400 miles on Amsoil, and I hope it comes out well - but if not, I will not use it again. I spent about $8 per quart for it, so anything less than a stellar test will be unsatisfactory to me.
I am currently testing M1 Truck and SUV, 5w/40 in the bike now - it's 5.99 per quart, and when I do a UOA, if it's not an excellent report, that too will be gone...
So, what am I saying? Whether it be motorcycle or automotive oil, I think testing it is the key, and then make an informed decision based on the evidence and the results.
No doubt the oil manufactures would love to take the same auto oil, throw some extra's in it, and then double or triple up the price --- they are in business, and ultimately, their bottom line is their primary focus...
Just my 2 cents worth...
