    Top of the line delivered quickly
    By  NICK A.,  a  Verified Buyer  from  Intl Falls MN  on  November 27, 2021
    In my opinion this is the highest quality oil you can run in any vehicle or machine. While it is a little more expensive than some others, it is engineered for enhanced wear protection over a greater time frame. Also it was delivered within 3 days which is always nice.
    Bottom Line
    Yes, I would recommend this to a friend.

    Buick Cascade
    By  PORTER,  a  Verified Buyer  from  Military Base Korea  on  November 26, 2021
    I only run Amsoil products mostly. After the change from OEM Dextrose to Amsoil 5w-30. I noticed again that things are a little more quiet. Valves and little ticking sounds in the motors always seem to go away.
    Bottom Line
    Yes, I would recommend this to a friend.

    Solid oil
    By  JAY,  a  Verified Buyer  from  Arizona  on  November 25, 2021
    I use amsoil in all my trucks. I've never had issues with it and it's still in pretty good shape after each oil change. It's worth the money if you like your car. Some people are fine with whatever they get at jiffy lube, but I am a little more picky with my oil. And this stuff has been proven good and it's got the reputation to match.
    Bottom Line
    Yes, I would recommend this to a friend.

    Bottom Line
    Yes, I would recommend this to a friend.

    The best oil I've ever used
    By  ROBERT,  a  Verified Buyer  from  Centreville, VA  on  November 24, 2021
    Signature Series got me to 282,000 miles on my 2015 Chevy Cruze in 3 years driving Uber. I probably would have gotten a 100,000 more miles but I only started using Signature Series at 110,00 mile mark. It's the best. Anyone that really knows motor oil already knows this. My next new car will have all the fluids replaced with Amsoil products before the first 10,000 miles.
    Bottom Line
    Yes, I would recommend this to a friend.

    one of the best
    By  ANDREW,  a  Verified Buyer  on  November 22, 2021
    It's engine oil. There's not much more I can say about it. It's one of the best out there. I noticed more of a performance difference from this oil than when I used Royal purple hmx so it's a thumbs up from me
    Bottom Line
    Yes, I would recommend this to a friend.

    Very good product
    By  Derrick,  a  Verified Buyer  from  Kansas  on  November 21, 2021
    Been using this oil for a while. Always looks good still even after a 10,000 mile routine oil change. Now I know I could go longer between oil changes but I personally don't like to. I run this oil in my Ram 1500 and my Dodge Grand Caravan. Love love love this oil!
    Bottom Line
    Yes, I would recommend this to a friend.

    Only oil I will run in my 06 Jeep srt
    By  JOSE,  a  Verified Buyer  from  Longmont   on  November 21, 2021
    I will only run this oil because other oils burn too fast in my engine. Amsoil on the other hand burns much slower and only have to add a quart after a long night at Mexico.
    Bottom Line
    Yes, I would recommend this to a friend.
