That said, I believe some of the n55 folks here track their cars, maybe some of them can chime in?

If you're still uncomfortable, you can now do the s55 oil pump swap and have bullet-proof oiling, as long as it's a RWD car (s55 oil pump unfortunately doesn't work with the x-drive oil pan). There's even a guy on here now selling the custom brackets needed for the conversion.

For what its worth, I asked Google AI for its thoughts on the matter. Here's what it said:
Wow thanks for the thorough answer brother. I appreciate it!
