    SWITCHED
    By  gregory,  a  Verified Buyer  from  Indiana  on  August 21, 2023
    I stopped using amsoil and switched back to mobil1. I noticed the oil got darker much sooner than when I was using amsoil. So I went back to amsoil.. Since my intervals are longer with amsoil the costs are real close to the same. This is the good stuff. running it in my ford edge 2015 3.6L
    Bottom Line
    Yes, I would recommend this to a friend.
