There was a Super Tech oil filter on my 97 Stratus V6, which is a larger filter (ST16 I think). I went to change the oil myself and put the metal oil filter removal tool (the kind that goes over the entire bottom end of the filter) on it, connected the socket wrench and turned. The filter was on pretty good, but the filter just became rounded at once and the wrench was useless. The removal tool is spcifically for this size filter, too! I've never had this happen. So I commenced pounding a screwdriver through it and finally did get it off. Think this was a bad filter or what?
