First UOA post on BITOG; long time forum observer
Pretty boring run, but Blackstone marked the oil as a 5W30, while my dealership receipt called out "Bulk 5W40, 229.5 spec." a year and almost 10,000 miles ago. I thought they told me they use Mobil 1, Blackstone noted afterward in email that their experience with that grade from M1 has a lot more magnesium among other things, but it does look a lot like M1 5W30. Anyway, I'm not sweating the details as the UOA looks to be great for this engine type. I did my own oil change this time and poured in M1 0W40 FS and a MANN cartridge filter for a 10k run.
