This is exactly what I have always been looking for. I am a happy Amsoil user, but I still want to see some facts, like how well does the oil protect with 25K of wear on it. I would love to see the 4-ball wear test with this used oil. Comparing new oil only says so much.
One good thing is from the UOAs I've seen, it does seem to hold up well. I have never seen a UOA with 12 months and a lot of miles, like over 15k-20k.
