The reason you see filters like Frantz on big rigs and heavy equipment is there engines cost tens of thousands to rebuild. So for example installing one on lets say a Cat 797:

Say you run it 350 days a year, if its at a mine it goes 24 hours a day=8,400 hours a year. Now figure that the thing probably holds 20 gallons of oil if not more, and changing it is down time. So spending $500 to plumb in a Frantz to not only maybe get a few thousand more hours between rebuilds, but also reduce down time for maintaince.

If one was to figure out what a 797 costs and how much its time is worth you can do a cost benifit on the Frantz and see if it pays.
