I switched away from Blackstone. Previous UOA is here. UOA history for this vehicle is available with this search: https://bobistheoilguy.com/forums/s...le_only]=1&c[users]=Emperors6&o=relevance&g=1. Going forward going to run an OCI of 6mo/5k miles since I can do oil changes myself and the engine is getting up there in milage and want to keep it for longer.
