I just changed my OEM filter @ 30K miles. Looks pretty good. I have inclosed pix of the other OEM & Cat filter for comparison. I have always run additives on this set of filters. Mostly FPPF TP & 8+ cetane boost. Of course, the 2 stations I get fuel from seem to be exceptionaly clean!! http://www.dieselplace.com/forum/smileys/Clap.gif

Here are the pix:

Here is my first OEM with No Nicktane and 11K miles:

As posted before, Here is my 1st Nicktane Cat 2um pre-OEM @19.5K miles

I think my filter changing schedule will be: The Cat filter every 20 -25k miles & the OEM at every 40K miles (As long as I have good fuel)!

I'm Happy with these results http://www.dieselplace.com/forum/smileys/Clap.gif http://www.dieselplace.com/forum/smileys/Clap.gif http://www.dieselplace.com/forum/smileys/HiHi.gif
