    6.7 Cummins needs the assist
    By  ALLAN,  a  Verified Buyer  from  OK  on  January 18, 2023
    with the egr on these the oil is even dirtier than previous diesel engines w/o egr. not expecting the oil to look exactly like out of the bottle new, but I know this filter is catching the extra contaminants from the egr system.
    Bottom Line
    Yes, I would recommend this to a friend.

    Poorly packaged
    By  MYRON,  a  Verified Buyer  on  November 16, 2022
    Packed in a manner so the product protects the paper. Shouldn't the paper protect the product ?? 🤔 Have pictures if you'd like to see. Tell your buddy Bob he needs to sharpen his pencil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Detroit 4-53 Install
    By  Bill,  a  Verified Buyer  from  Gulf Shores, AL  on  October 22, 2022
    Installed on my duel 4-53’s on out Hatt LRC. Teeing into the oil pressure transducer as directed by documentation, caused too much pressure drop at the transducer. Both idle and WOT pressure reading off by at least 50%. There is a port on the front of the oil pump on front of engine I used as a supply to the bypass filter instead.
    Bottom Line
    Yes, I would recommend this to a friend.

    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.

    Bottom Line
    Yes, I would recommend this to a friend.
