had oil changed with Ammco in memphis Tn. They put the wrong oil in, then later changed it back. This left a rattle in engine.
does this car have adjustable valves on its engine? on 2006 Mercedes-Benz C230
What kind of oil did they put in 'it shouldn't make a difference?

I have had a similar problem. I had a cheaper quality filter made by lubrifiner and ended up with a rattling lifter or two. I am in the prosess to getting parts to change them. not nice, I was told by Mercedes to use good quality filter or this happens. There is no adjustment as they are hydrolic.
