Oil filters....which one to use?
I run a Napa Gold (Wix) 1348 or Wix P/N 51348 which is the filter for the V6 Dakota and Neons. It is smaller and easier to get to with the headers and there is no need for that leaky adaptor. Baldwin, Fleetguard, Wix, Purolator Pure One, Donaldson, Amsoil (Which are made by Donaldson) and Mobil are probably the best filters out there. If you buy a Cummins truck you have a list of approved filters that you must use.....if you don't and there is a failure cause by the filter it's on you. Most filters aren't up to snuff and the media disinegrates under the higher pressures and will clog oil passages. Filters are just as important as oil if not more important. The toilet paper filters are alive and well under the Frantz name:

They are meant to be used as a bypass filter not as a full flow filter.....they have a following with the diesel crowd because they offer extended drain intervals but you should use oil analysis to confirm the extended intervals.
