    Works wonders
    By  Sam,  a  Verified Buyer  from  Nebraska   on  February 17, 2024
    After running this oil in our SUV it helped to run quieter and reduced oil consumption to none. I would recommend this oil to anyone with a higher mileage engine. Just keep up on your oil changes and Ams Oil can really make a difference in your engine.
    Bottom Line
    Yes, I would recommend this to a friend.

    Low on power
    By  DAVID,  a  Verified Buyer  from  S Texas   on  February 17, 2024
    Been using this on my 327000 97yukon 2door and truly think Amsoil is the only reason why my suv is still running as strong with no engine issues. I drive my truck seven hours to west texas towing a 171 jayco once I get there I idle my truck while working for 13-14 hours a day in heat, cold, rain, dust storms, and still drive it back to south Texas after my fourteen day hitch. I send my oil samples through the company I work for and have never got back a bad or concerning sample even if go over my mileage intervals. I would never leave amsoil and take a chance with any other oil
    Bottom Line
    Yes, I would recommend this to a friend.
