$100 Site Donor 2021
As the title states, this is the most recent UOA from my Grand Cherokee using @High Performance Lubricants Super Car 0W-40. The previous run is Ravenol SSL 0W-40.
Engine is breaking in nicely, iron per 1,000km dropped more than in half from the previous UOA, going from 7ppm/1,000km to 3ppm/1,000km.
BL is the Super Car 0W-40, so this oil. (I don't have a Ravenol baseline from OAI, that was from Toromont CAT, before I switched labs).
Copper is coming down as well.
Viscosity held up very well, there's a bit of fuel dilution. TBN and nitration both took a good hit, and there's a bit of oxidation there too.
