I'm not sure who exactly left the impression that he spoke out of his ***. One respondent said that there was a significant design difference between OEM and Wix in his application and another respondent, a veteran MB tech BTW, presented a reflection of his experience. Unfortunately the responses thus far have not had the substance to convince the thread initiator that a Wix oil filter is or is not appropriate for his car. They seem to have succeeded in convincing you that you are among the minority of respondents that knows what they're talking about.
