Hello there, first post here but not first time here. I am curious if anyone here has run the Donaldson DBL 7405 filter and noticed an improvement in their oil analysis? Or if they can offer any pros and cons, even if it's only based on anecdotal evidence. I've run the 7405 on my '92 7.3 IDI diesel for a couple years now and like the idea of more filter area even though my OCI is only 5k(dino), which is the OEM spec for normal duty--not sure if that number is from Ford or Navistar though. Oddly enough I pay less for these massive Donaldson filters than NAPA charges for a 7.3 PSD filter.
