As I think about their testing methods...they don't account fer dirt going through their filter and picking up oil. They only tested it with clean air. I can see how any medium going past the filter will pick up the oil as well as other dirt that has been trapped and dislodged by other mediums gitting past the filter. <img src="/forums/images/graemlins/smile.gif" alt="" /> <img src="/forums/images/graemlins/wink.gif" alt="" />
