I have no problem with the tests on virgin samples, it keeps the playing field level.
I am more interested to hear what members that are very experinced in dealing with these tests can help me to learn from them. I have been leaning towards trying Amsoil, I've been a Mobil 1 user for nearly 10 years....lol....but you know what they say about the fence and greener grass on the other side. I recently bought a new bike and I've been considering trying some new oils and doing some UOA's. I wanted to try Amsoil,Royal purple, and test my Mobil 1. Someone was saying in this forum a few weeks ago how Royal purple is 400% more shear resistant. Obviously, according to this paper, this is not true. Mobil 1 seems to have a sever foaming problem, that I need to find more about.
So I may test my Mobil 1 and I'd like to try Amsoil, my main problem with Amsoil is finding it...I've been looking for weeks and I cant find it anywhere, besides online.
I wouldnt bash the virgin sample tests, its a great starting point. Its our job to take it from there in our own bikes and UOAs, since there are so many variables from bike to bike, locations, drivers etc.
