Hi all,
I have a 2004 S500 (m113 engine) and did an oil change yesterday.
Have been using shell 5w40 fully synthetic oil for years. But yesterday, I switched to Motul 8100 5w40 100% synthetic.
I noticed that the car runs better but the engine sounds louder than usual in high RPM ranges (3500 +) and when accelerating hard from a stop.
Initially thought that it was the exhaust that became louder. But realised that the louder (deeper "v8") sound comes from the engine.
Would appreciate if anyone could help.
Thanks
Jake
