Bypass oil filter systems

[Shandro]

First hand experience is always the best kind. Documentation and reports can only take a person so far. On the mack there are already 2 full flow filters and a separate bypass filter right from factory. So I'm not to sure adding something additional will help to much. Got in touch with gearhead to do a tune on this truck and hopefully after that the oil will start to clean up once it running like it should.
