I have posted all my results of both used and virgin oil here: http://theoildrop.server101.com/ubb/ultimatebb.php?ubb=get_topic;f=3;t=000380
The virgin samples are Amsoil 10W-40 and 75W-90, and Mobil 1 10w30, I don't recall the "formulation" of that Mobil 1, it might pre-date their Tri-Synthetic even.
