5um contaminant testing was originally planned to be conducted on every filter. However once starting with the 51060 filter, it was apparent that all but the most efficient filters would let too much of the contaminant pass. The 51060 took 5 full passes through the testing filter papers (2 fully clogged filter papers) to even begin to get the test oil to be visually less contaminated.View the Wix 51060 specs page to see the test results. Due to all the extra time and problems associated with the 5um testing on the Wix filter, I only conducted it with the top 2 performing filters from the 30um test, the Royal Purple, and Amsoil, and even those required 2 testing filter papers each. The results to those tests are available on their specific pages.
