Guys pls- I'm only referring to N54 engines. Ok. Manual states only 5w-30 or 5w-40. All cars over the miniminun sheer mark- 50k miles, would be better off with 5w-40 due to piston shearing.
Pls do not confuse the cold ticking start with rev clicking at all temps. Just my 2 cents. If u have a metallic clicking noise at 230f that is loud enough to hear inside the car, I would get it it looked at. Simple.
