So my Civic has had some work done in the past 10k miles. Head gasket at 158k and crank seal and oil pan gasket at 164k. This oil was put in shortly after 164k. I expected silicon to be high from the work at 164k, and it was. Iron is still high from the HG change, but it's going down incrementally based on PPM/1000 mi. What I'm kind of stunned about is how much viscosity the M1 AFE 0w30 lost. I've heard it does lose a lot of viscosity with use, but was not expecting it to go from 11 ->8.6 in an engine without DI. I'm wondering if there was some fuel involved because the one VOA I have of this oil shows a starting flashpoint of 455, while the flashpoint in this UOA was 410. I knew the TBN would be high, but I got it anyway just out of curiosity. 5.2 indicates it could've gone a lot longer. Here's the oil report:
And here is a breakdown of PPM/1000 miles, compared to Universal Averages:
You can see everything compares favorably to Universal Averages except Iron and Silicon.
The oil that went in was Valvoline MaxLife 150K 5W20. I'll change and sample in 6 months.
