Car has 80,400 hard driven miles.It is taken to road race events, this sample represents 13 hours of track use(4200 RPM to 6000RPM at 280F+) The data(which represents 8 years) is listed from newest sample on the left to progressively older data. First data set(RL 20W-50),Second data set(RL 10W-40),Third data set(RL 10W-40)Fourth data set(RL 10w-40),Fifth data set(RL 10w40),Sixth data set (RL 10w-40),Seventh data set (RL 10w-30), Eighth data set(Amsoil 10w-30 + red bottle Valvoline Synpower), Ninth data set(Amsoil 5w-30); Most recent analysis used an Amsoil EAO23. Data sets four thru nine performed by Analytics Inc, Data set one, two and three were performed by Oil Analysers. 3 quarts of RL 20W-50 were added during the 2400 mile change interval.
Oil Analysers flagged the oxidation as severely high and nitration as moderately high, but Dave at Redline says these are normal readings for ester based oils and to ignore it. They also flagged the Nickel as being at a significant level. I routinely use MMO in the gas. I switched to Redline 20W-50 from the last analysis.

By the way, I "recycled the oil" I'm putting the used oil thru my Saturn when it needs oil added(which is often!)
