    Long time user
    By  KARL,  a  Verified Buyer  from  Pelham, Alabama  on  August 16, 2023
    I’ve been using AMSOIL products for more than 20 years in every car I’ve driven in that period of time and I’ve never had a major mechanical problem of any kind. My current personal vehicle, a Ford Explorer with more than 111,000 miles on it is showing no signs of wear. I will never use any product other than AMSOIL.
    Bottom Line
    Yes, I would recommend this to a friend.

    Really helps as claimed
    By  SCOTT,  a  Verified Buyer  on  August 03, 2023
    All around impressive stuff and easy to use just wish it had a reminder sticker when to add the next batch. Other than keeping track odometer and writing down the mileage it’s a no fuss for win for you and your vehicle. Will for sure be using when needed again.
    Bottom Line
    Yes, I would recommend this to a friend.

    Bad bottle
    By  TODD,  a  Verified Buyer  on  August 01, 2023
    When I received the package the side of the box was wet with no signs of damage. When I opened the box it was obvious one of the bottles had been dropped and was leaking. You would think there would be some sort of quality control when it come to shipping chemicals. About a 1/3 had leaked out. Should have called but at the time I was to busy.
    Bottom Line
    Yes, I would recommend this to a friend.
