    Time
    By  MICHAEL,  a  Verified Buyer  from  Menifee. California   on  August 24, 2022
    The 2 micron bypass filter permits much longer oil change intervals without harm to the engine. On our diesel, we typically do 30K oil changes. But the truck is only used for highway towing. Lab reports always come out perfect. It's quite a savings as oil certainly isn't cheap.

    Only AMSOIL?
    By  victor,  a  Verified Buyer  from  TX  on  August 14, 2022
    I'm afraid AMSOILS multilevel marketing system (Ponzi Scheme) has finally run it's course. I have been using their products for many years but their dramatic price increases is going to make me an ex-customer. This is a great filter but as far as I know AMSOIL is the only one that makes it. If I can't find another source for this filter I will remove my whole AMSOIL bypass filter kit and find another kit. I've already switched to Royal Purple diesel oil. I'm sure no one will see this review.
    Bottom Line
    Yes, I would recommend this to a friend.

    EABP100-EA FILTER
    By  RIck C.,  a  Verified Buyer  from  Lecanto, Fl  on  August 07, 2022
    I've been using this bypass filter for 2yrs now. And I can noticeably see my engine oil staying cleaner between changes. This is a must need product, especially for Diesels with EGR Valve still on vehicle. Note: I change this filter w/every oil change at 5K miles.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great add-on system.
    By  GREGORY,  a  Verified Buyer  from  arkansas  on  July 11, 2022
    system is not hard to install at all. i didn't want mine on the outside of frame mounted it to the opposite side of the bracket my Airdog is mounted too. I did purchase 2 90 degree JIC swivels to keep my oil lines from being in a bind for where i mounted the system. I wish i had done it sooner.
    Bottom Line
    Yes, I would recommend this to a friend.
