    By  GREG,  a  Verified Buyer  from  Indianapolis   on  January 04, 2022

    The very best peace of mind is protection. I use this in conjunction with a factory KOHLER filter on my commercial ZTR Mower. Extra protection through 500 hrs of use. No engine wear problems or failures as of yet. 1200 hrs on motor with 3 AMSOIL EABP90 filters used to date. Great product!
    Bottom Line
    Yes, I would recommend this to a friend.

    works well
    By  JOE,  a  Verified Buyer  from  oklahoma  on  December 23, 2021

    Describe the issue

    I got this filter to replace the one that came with my dual bypass kit. I have driven 70k on it. I dont do oil samples so I cant show numbers. But it does give me peace of mind. I run my pao 5w40 oil 2 change cycles so about 15k and this helps make sure the oil stays as clean as possible. the added oil capacity does not hurt either.
    Bottom Line
    Yes, I would recommend this to a friend.
