Donaldson makes a filter that is comparable, but I do not know of a reliable source...pretty sure Donaldson makes the EaO for Amsoil. The CM is an alternative, but has a pretty steep initial cost:
These filters do not have a bypass...they filter all the oil and have exceptionally high flow rates. CM says the filter will last 10K under normal use.
Another alternative is to use a dual filter head with a conventional filter on one side and a Trasko bypass filter on the other...you want the T3/4-20S:
After the 1st change at 4-5K (cleans the motor out), you could achieve keeping both filters on for 8-10K...the key wll be the visual inspection of the Trasko. You can see the crap from your motor work it's way up the filter on removal. This allows you to adjust the next interval.
The benefit of going this route is your oil will be very clean (< 1 micron for particles)...a bypass filter removes all contaminates. You can run your oil until Blackstone says to change it...I've seen oil go 15-16K (a couple times more than that) before TBN was depleted. The change interval is going to depend on how much make-up oil you add over time that replinishes the additives.
