I got my results of the UOA. No fuel dilution. Less than 1% soot. Plenty of Moly/Calcium/zinc in the additives. TBA above 2.0.
I have redline diesel 15w 40 in the sump. There was a flag on the oxidation, but their note said that happens with some types of synthetic and that they can't determine extent of oxidation. A search on the internet shows many people doing UOA with redline (ester-based) oil using Horizon/Polaris/Oil Analyzers and their tests for oxidation with redline (which is a group 5 ester-based oil) often gives a "severe oxidation" result. A source on the internet says a redline oils tech rep confirms that it doesn't mean there is oxidation.... it is just the type of oil.
I will submit an unused oil sample to them for analysis and comparison.
Oil Analyzers which is a Horizon/Polaris labs company in their report didn't suggest changing the oil. They gave me a green 1 rather than a red 4. Red 4 means critical. 1 is green, 2 is yellow, 3 is Orange, 4 is red.
So I will continue using the oil while they analyze the fresh/unused sample that I send them. Wear metal levels in the oil were low. 10 ppm iron was the largest. Most wear metals were at 0-5 ppm. And since redline oil has very high detergent levels, that usually clean up anything that a previous sump of oil may have left behind, i have enough confidence to go at least another month on the current oil.
Edit: forgot to mention viscosity is 13.9.
