    Good product
    By  JOSEPH,  a  Verified Buyer  from  Kearny,NJ  on  October 18, 2024
    I like the oil. I always try to get the filter to go with it. I don’t extend my change intervals. I have noticed that the filter is heavy. I guess it is catching something. My truck runs good. I am a little afraid to cut the filter to see what’s inside. Could this be the oil sludge? I like the gloves that came with the oil. The cardboard funnel. I have yet to find a use for it. I have a skid plate and tried to use it to direct the oil away from the inside of the skid plate, but it was too small. Overall good oil. It would be nice if it was not so expensive.
    Bottom Line
    Yes, I would recommend this to a friend.

    Hybrid cars need really good oil
    By  ROBERT J,  a  Verified Buyer  from  Central Minnesota  on  October 17, 2024
    Amsoil Signature Series 0W-16 installed in my 2024 Kia Niro hybrid for its first oil change (1,900 miles). With the on / off operation of the gas engine, I wanted the best oil for it. Also like the low pour point for cold winter starting. I like the great additive package too. I have been using Amsoil since 1998 with great results and no issues.
    Bottom Line
    Yes, I would recommend this to a friend.

    The Best Insurance Policy
    By  RICHARD,  a  Verified Buyer  from  Rockwell, NC  on  October 17, 2024
    I run this in all our vehicles including my daughters. The girls typically travel less than 20,000 miles per year so I change their oil once per year. In my turbo charged vehicles, I change at less than 10,000 miles. I typically see a 10% fuel consumption savings which, I feel, is a testament to the reduced friction.
    Bottom Line
    Yes, I would recommend this to a friend.

    New engine
    By  THOMAS,  a  Verified Buyer  from  WV   on  October 15, 2024
    Buddy of mine owns a Ford F150 had to replace the engine so he wanted to give Amsoil a try after I had given him my thoughts on how good Amsoil is. The new engine is still in the "breaking in stage" update will come later.
    Bottom Line
    Yes, I would recommend this to a friend.

Highly recommend AMSOIL.

    None better
    By  RALPH,  a  Verified Buyer  from  Tennessee  on  October 14, 2024
    Well pleased with the product. The testing and results seem to prove that protection for the long term is guaranteed. The Q & A regarding the oils are quite informative and have caused me to rethink many of the (incorrect) assumptions I have made over the years. Currently, I'm driving a Durango SRT and am well pleased with the smoothness and performance of the hemi since changing to the Signature series oil recommended. It's always good to research potential issues with an engine/power train and see how a specific action will help to mitigate a given problem. In the case of the Dodge hemi, premature cam and lifter wear seems to be an issue with engines left to idle for extended periods and/or run for extended oil change intervals. The Amsoil Signature series oil is well suited to mitigate the problem. Time will tell, but currently 70,000+ miles have not changed the 'as new' performance or noise levels in a great engine.
    Bottom Line
    Yes, I would recommend this to a friend.

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

    Only Oil I use in my CT5 Blackwing
    By  TONY,  a  Verified Buyer  from  Jacksonville FL  on  October 13, 2024
    When I was a kid, I would help my dad change the oil in his work truck and he used AMSOIL and taught me at a young age that changing your motor every 3000 miles will make your vehicle last. Now it is easier because oil last to 10000 miles. Thank you AMSOIL!
