    Best oil on the market..
    By  JEFFREY,  a  Verified Buyer  from  Silver Point TN  on  May 25, 2026
    I’ve used Amsoil products for 15 years in all my vehicles, side by sides, motorcycles and machines. Every one still running strong without issues. I love the fact that all can be purchased as complete kits through Amsoil.

    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.

    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.

    Best product on the market
    By  MICHELE,  a  Verified Buyer  from  Durham, Maine  on  May 22, 2026
    My husband was an Amsoil user for many products before his death and was totally convinced that Amsoil was the best product to use. He used their oil in all his equipment, truck, car, yard tractor and snowblower. He would always recommend it to everyone he knew. Since he has been gone, I have picked up on his recommendations and I would never use anything but Amsoil oil.
    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.

    Can't go wrong!
    By  WOODY,  a  Verified Buyer  from  TX  on  May 15, 2026
    Been using this oil ever since 2020, and have used it on other cars as well. It has served me well, as I send my oil in for analysis, and it always comes back positive! I use this oil in the winter here, so it warms up quicker, but in the hot summers I use a little a thicker oil...same brand!
    Bottom Line
    Yes, I would recommend this to a friend.

    Great product
    By  Bama68 ,  a  Verified Buyer  from  North Carolina  on  May 13, 2026
    Have always been impressed with Amsoil products. Ran Amsoil products through my Late model Dirt car. I got to the protection first hand. After that I put in my personal vehicles. Do the math and you actually save money protecting your vehicles with Amsoil products
    Bottom Line
    Yes, I would recommend this to a friend.
