Decided to try it out, from what I understand it is an extended drain filter with a 2 part construction. One section is a standard stratapore filter and the other part is a stacked disc section that is supposed to filter down to very fine micron level. I dont know the specs. I changed the oil a few weeks ago, I checked my oil level today and was amazed that my oil was still golden in color. This oil has appx 1800 miles on it. I've always seen and been told that diesel oil turns black almost immediately after running it. And this has always been what Ive seen with this truck, UNTIL I put this filter on! What do yall think?
