Totally not true with my experience in 2000 MB E430.
My E430 is much quieter with either PP 5W20 or M1 0W20 than M1 0W40, it also run much smoother with thinner oils.
Interesting how it varies depending on the vehicle. Mine is definitely quieter with the 5w40 over the 5w20. I had the hood open to check the transmission fluid tonight and heard something. As I was trying to figure out the noise I heard... it dawned on me.... it was the injectors. I hadn't realized until that moment that the other "normal" noises the engine had been making were now quieted to the point where the only thing I HEARD was the injectors and the fan!
