Just changed the oil in the 190e (215k miles) to 15w-50 synthetic.

Remarkable difference. Engine is much smoother. Both passengers noticed it immediately, at idle and while driving. Much quieter as well.

I believe there are two reasons .... first the benefits of a synthetic oil which is 50 weight, but also because the chain tensioner probably got pumped up or cleaned out and the engine timing being improved.
