    You still haven't spoken to your buddy bob about his pathetic packing. Are you afraid to speak to him ?? Any further questions about "How'd we do ?" I will just rate one less star each time.

    Part of my Dual filtration package
    By  DOUG,  a  Verified Buyer  from  Calif.  on  April 24, 2023
    When I started using Amsoil products, I added dual filtration. Currently I have 241K on my 2002 Superduty Truck and I hope it continues its service to us for many more years to come. It keeps the oil cleaner longer and I am not worried about longer service intervals between changes after a number of oil analysis's have shown the oil is in good shape.
    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.
