Amsoil says to change the eabp120 bypass filter (big boy) @60k or 1 year, I know they are in the filter business and want to sell filters.

I am running Donaldson blue dbl3988 synthetic media ff filters (x2) on the 60 series detroit.I know a lot of you say to run a bypass filter until it gets cold and stops flowing, I am just wondering what reasons amsoil would have besides profit , warranty,deterioration ...esp since a bypass filter gets better with time. The Donaldson blue filters are rated at 15 microns so I would think that assist in keeping the bypass a little cleaner... What say you???


My 3 trucks with bypass setups are now at 29k,24k ,and 22k. I will post my findings when 2 trucks reach 30k

15 microns is excellent, but not enough to catch soot.

Run the bypass until it doesn't flow anymore grin

If it does not warm up with the engine, change it.
