Well, you're right about one thing.

We will see how bad the oil is next week. It probably has plenty of TBN left. The engine suffered through 7500 mile 2 year dealer oil changes with various Castrol products (usually syntec blend) before I got it so it isn't super clean like the other car. Also even new M1 0w40 is darker than for instance 0w20.

There may be something to that, the Distance Plus had similar bunched pleats and if the equipment glues it together crooked, it is going to stay crooked.

Let me look, if not I may sacrifice my last one of these - I'm not excited about using it anyway.

It did the job - at least it appears to have done the job, to the extent one can tell by looking.
It didn't look very good doing it though...
