1. Vanos relies on oil pressure to operate.accurately.
2. Lifters rely on oil pressure.

Why would changing oil not impact these things and many others?
Thank you! My point exactly is that we are changing from bmw recommended oil based solely on the bearing clearance/cold start wear issue, without thought to what other effects (if any) this might have.
