    The best oil
    By  JAMES M,  a  Verified Buyer  from  63130  on  April 30, 2023
    Been using Amsoil for the last 20 years and every car I have used it in never burned oil and and never leaked. And I keep my cars for a long time most of them have 200,000 miles. Will always use Amsoil no matter how the manufacturers try to bad mouth it or try to get me to use their oil. Had a few cars where the manufacturer had recalls on oil burning and none of my cars burned oil using Amsoil. Maybe the car manufacturers should start recommending Amsoil lol.
    Bottom Line
    Yes, I would recommend this to a friend.

    Stand Alone the Best
    By  DAVID,  a  Verified Buyer  from  Oklahoma  on  April 29, 2023
    Have a 2009 Volvo and have used Amsoil for the last 120,000 miles. Currently I have 211,000 miles on my vehicle and runs as smooth as a new car! I have used Mobile 1 in past before I switched to Amsoil. There definitely a difference in how smooth and quiet my engine runs. Mobile 1 is good but Amsoil is definitely a step above and worth the extra $ u pay to have your engine run at peak performance
    Bottom Line
    Yes, I would recommend this to a friend.

    Amsoil is Great
    By  SCOTT,  a  Verified Buyer  from  Ohio  on  April 29, 2023
    I have been using amsoil for 20 years. My engines out last the rest of the car literally! All vehicles had over 250k+ miles. Love this stuff with up to a year between oil changes and you can also add a couple MPG beyond what the MFG states, which was my experience.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best I've used
    By  jjocky,  a  Verified Buyer  from  FL  on  April 27, 2023
    I chose this oil because the manufacturer required an oil with an SN+ rating. This one has it and is at the 0W-30 the manufacture recommends. In the purchase deal I received one free oil change. I took it in at the 10,000 mi interval they recommended. I had already done 2 oil changes up to that point using Amsoil. The dealer put in their branded oil. Before I had to change oil again, I needed to add oil. With Amsoil I never need to add oil between oil changes. It's much better oil in my opinion.
    Bottom Line
    Yes, I would recommend this to a friend.

    Not a fan
    By  BRADLEY,  a  Verified Buyer  from  Peoria, AZ  on  April 24, 2023
    I wanted to possibly upgrade oil from royal purple to Amsoil and I tried to however I went with a Amsoil oil filter for my Jeep JKU and the filter did not fit as Mopar filters do. I lost faith in the idea of upgrading from RP to Amsoil. I ended up replacing the Amsoil filter and oil after 3 days as I didnt like how the filter went in. I am a avid fan of changing engine oil sooner than later.
    Bottom Line
    No, I would not recommend this to a friend.
