ENGINE OIL SPEC

Hi All

This is my first post, I own a Mercedes C220 CDI (diesel) 2002 classic I have had an oil and filter change done about 6 weeks ago and I am sure the engine sounds more noisey since then? (Sounded better with dirty oil) The oil used was 5w/40 grade fully synthetic
My question is what is your recommendations be to use fully synthetic or part or mineral oil and what grade and is there anything to be concerned about

Thanks in advance bluepassat

RE: C220 CDI ENGINE OIL

20W-50 is better.

RE: C220 CDI ENGINE OIL

Regular oil or full synthetic? Mercedes recommend Castrol SLX 0w/30 full synthetic I think that’s very thin
I was hoping some one on this forum would have experience of what the most suitable oil was
