    Running sweet down the street
    By  JOHN,  a  Verified Buyer  from  Palm Coast   on  May 18, 2024
    I have been a long time user of Amsoil. I always used it in my work vehicle since I traveled a long distance. I would change my oil at 15k miles and was amazed how good it still looked. After seeing that I decided it was worth using it in all my vehicles including my motorcycles and lawn equipment. You will have me as a customer for life!
    Bottom Line
    Yes, I would recommend this to a friend.

    Hands Down Best oil
    By  BRAD,  a  Verified Buyer  from  Las Vegas   on  May 13, 2024
    This is the best oil period. Worth every penny just for the peace of mind you get with running the best oil there is. Project farm (on YouTube) did multiple tests against all the top brands and Amsoil came out on top. Also it's the easiest bottle to pour.. I run it in my Harley, Cadillac, and all 4 of my heavy duty diesel work trucks.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great Product
    By  ROBERT,  a  Verified Buyer  from  Delavan  on  May 13, 2024
    The one and only issue I have with this product is the oil filter. I wish for a design that a traditional filter wrench is not required. On the Harley Touring bikes it’s a pain to get filter off. Hate to say it but many will use the K&N filter due to the hex requiring a socket. So much easier
    Bottom Line
    Yes, I would recommend this to a friend.

    Compared to other oils, not a lot of discoloration due to thermal breakdown. Reduces engine noise.
    Bottom Line
    Yes, I would recommend this to a friend.
