This is a first sample with known oil and change interval, from about one month of RV transporting. 50% loaded, 50% empty duty cycle.
Polaris comments:
Flagged data does not indicate an immediate need for maintenance action. Continue to observe the trend and monitor
equipment and fluid conditions. OXIDATION is at a MINOR level, which may be due to extended drain interval or high operating
temperature. Iron is at a MINOR LEVEL. IRON SOURCES in engines can be cylinder liners, iron pistons, hardened steel
camshafts, crankshafts, gears, hardened rocker arms, valve bridges,alloyed steel cam follower rollers, etc. Lubricant change
acknowledged.
Iron wear is up significantly, but it isn't necessarily the oil because the miles on the previous oil sample was unknown. But the wear rate is pretty high compared to the later UOA's of my old truck.
Soot of 1.2% is significant, and may be a normal thing with an EGR engine.
Since the filter only had 11k miles on it, I did the oil change to RT6 without changing the filter, so the next sample will still have ~9% Delvac 1300 in it.
I still don't like the weak additive package of Delvac 1300, and probably won't use it again, at least without supplementing with a ZDDP additive.
The oil that was in the truck when I got it looked much better for antiwear.
