We think that would be a reasonable goal for your next oil run, if you'd like. The 5.2 TBN shows plenty of active additive to spare and we didn't find any contamination along the lines of excess fuel, coolant, or dirt that might slow the engine down. We look forward to building trends for this BMW!

Here's my results with Redline 10w40. Thought about switching to 300V.
