Anybody have a guess on why the oxidation went up 700% vs the Delvac 1? Pretty much the same driving all the time nothing unusual or abnormally different.

Esters in the Redline will give falsely elevated oxidation numbers.

+1 to what Extreme-Duty said. Same for m37charlie regarding esters.

Most likely the oxidation numbers did not go up. Did you send a VOA along with your UOA? I had this same issue with a CAT lab back east. I ran AME 15W40 for 15000km's and had sky high oxidation. When I called the lab, they told me they simply had nothing to compare the oil to. I sent them a voa and they re-ran the sample and it looked normal.

Very good question...
Happens everyday. I still remember how bad Royal Purple was because one guy ran it for one OCI in his hopped up 5.3 GM engine.

60% of the time I send in a VOA, but I didn't on this one. I think I'm going back to the cheap stuff anyways.
