The ONLY thing that was changed was the oil filter. The oil fill was not changed...I am still on the same Mobil 0w-40 from when I first changed it. The engine was ticking, I changed the filter, and ONLY the filter, and now it is not ticking at all. Draw your own conclusions, but I can't think it gets much clearer than that.
I just received a MAN filter in the mail, and plan on changing the oil and filter when this current fram hits 1,000 miles. Still no response from Fram on the filter I sent in, but I will update when I get one.
Why don't you run the new Fram for longer? If it is quiet, then it seems to be working.
Btw, I also recommend going with the OEM filters. For German cars dimensional and design differences have been noticed between OEM and aftermarket cartridges.
