    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.

    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.

    Amazing filter
    By  NICHOLAS,  a  Verified Buyer  on  March 22, 2022
    Amazing filter. I dont know how many people can say that after and oil change that they can drive a few thousand miles and still see through their oil. I can though. This is my second filter. The first one I left on there for 25000 miles. The whole time my insoluble particle levels never got over .3%. I will definitely be making this filter a permanent part of my vehicle.
    Bottom Line
    Yes, I would recommend this to a friend.

    Good, but could be a lot better!
    By  Stephen,  a  Verified Buyer  from  West Virginia  on  March 22, 2022
    I bought this kit for a 2017 F-350 6.7 installation. The kit is not inexpensive, but *does* consist of extremely well-made components. Five stars for that. The big "meh," for me is, why aren't these kits vehicle-specific? At least the one for a Superduty is not. If you want an install to include a bracket stand-off to the Ford bottom stone guard, and a rock shield, and hose management parts, then you have to purchase a 3rd party "completion" kit. Two stars. The total cost of a well-engineered solution, with fluids, approaches $1000, and that has removed the smile from my face. Three stars.
