I need to change the air dog 100 filter which filter do I choose. I see the 2 micron and the 10 micron on amazon not sure which is best I believe there is a 10 micron in there now. Thanks

2 micron if possible. typically the Donaldson's Filters I pick up are typically 3 microns.

I change mine every other oil change. A lot of the guys here just wait until fuel pressure starts to drop.

 

 

D

Every 60k to 70k miles. 

 

15k miles the filter is still clean.

30k miles the filter isn't even discolored yet.

45k miles the filter showing a small sign of color.

60k the filter is discolored. Still good fuel pressure.
