    Best lubrication available
    By  MARK,  a  Verified Buyer  from  Winnipeg  on  May 24, 2026
    Obviously not a sports or muscle car, but I simply want the best lubrication and filtration available for my 2018 Honda Civic LX 1.5L Turbo and long engine life. The known fuel dilution issue with this engine is another reason for my choice of AMSOIL Signature Series 0W20 for my vehicle. I have also settled on WIX XP as my oil filter of choice.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  RICHARD,  a  Verified Buyer  from  Lake Havasu, Arizona   on  May 23, 2026
    I'm trying this oil after some research and switching from vavoline restore and protect. Not that it was a bad oil ,I cleaned my engine with it and then went with amsoil for the superior protection and extended oil change intervals. So far got 700 miles and still clean .I'm going to change at 7500.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  JEREMIAH,  a  Verified Buyer  on  May 22, 2026

    Best kept secret
    By  DogFace,  a  Verified Buyer  from  AR  on  May 22, 2026
    This oil has been without a doubt the best Ive ever used in a motor. My 2025 Wrangler 2.0L Turbo was very noisy from the factory. After an oil change using Amsoil my motor has never run smoother and quieter than it does now.
    Bottom Line
    Yes, I would recommend this to a friend.

    Happy GM 5.3 V8
    By  BRADLEY,  a  Verified Buyer  from  Cocoa Florida   on  May 21, 2026
    Amsoil is the best motor oil you can put in your car or truck. I have never had issues with this motor oil and even when I do go 5000 miles between changes the oil looks almost like it’s brand new. A motor oil may cost a little more, but believe me in the end your engine will thank you.
    Bottom Line
    Yes, I would recommend this to a friend.

    Made the change
    By  JOSE,  a  Verified Buyer  from  High Sierra, California   on  May 20, 2026
    Made the change 2 years ago and haven't used any other brand of oil since. My truck seems to like Amsoil and the performance is excellent. I can wholeheartedly say I will only use Amsoil in the future, as long as they keep the quality and care in their products. Their oil change kit is so convenient and considerate, they send you literally everything you need to do the job. And it's little things like that, that shows the care and pride that they have in their products. And that is something that I appreciate and respect. Every product I've tried or used from Amsoil is top tier. Definitely a company I can stand beside.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best oil
    By  Eddie,  a  Verified Buyer  from  Venus  on  May 13, 2026
    I’ve been using AMSoil for so long I don’t remember when I started, but suffice to say I believe it’s the best oil on the market and when paired with the preferred customer membership it’s the the best value too.
    Bottom Line
    Yes, I would recommend this to a friend.

    5w20
    By  ROBIN,  a  Verified Buyer  from  Yorkton Sk.  on  May 11, 2026
    I just did the oil change yesterday may 10th/2026. So so far so good. It would be cool to get a oil change kit with 5w20 as well for my 2022 RAM 1500 DT with the 5.7L just like the 0W20 oil Change kit. Because my mechanic says that the 5W20 is better for towing. Plus having a option for the 57060XP oil filter. But the oil I just started using this is my second time putting it in my RAM 1500. I heard good things so I wanted to give it a try plus it is so cool seeing how they take great pride in the manufacturing of there oil. I would recommend going with AMSOIL to everyone I know.
    Bottom Line
    Yes, I would recommend this to a friend.

    I definitely like it.
    By  BRANDON,  a  Verified Buyer  from  Farmville, NC  on  May 11, 2026
    I would definitely recommend the oil. Been running for over three years now. No problem at all. I normally buy the oil change kit that includes the funnel, gloves, filter, and oil. They did not have the filter in stock and I was not able to order the kit. Little disappointed but maybe it will be in stock next time.
    Bottom Line
    Yes, I would recommend this to a friend.
