For this OCI - the car was driven fairly regularly over two summers, then sat for the remaining time getting started occasionally over two more summers but remaining in a "storage" state.
If I recall correctly, this was still the LL-01 approved M1 0w-40 and and a BMW (MANN) filter.
I'm thankfully back to driving this regularly, so this summer I put a couple hundred miles on the OC before changing the oil/filter and taking this UOA sample. Now I'm thinking I should've ran it out much longer!
