    Great Protection
    By  Michael,  a  Verified Buyer  from  Slidell, Louisiana  on  March 18, 2024
    I've used this Synthetic Motor Oil 0W-40 since I purchased my 2016 Ram Power Wagon. After 157,000 miles and several oil changes, I can tell that I am getting the best protection for my truck in the main lubricant that my truck uses. During oil changes, I monitor the outgoing fluid and sometimes take apart the oil filter just to check for normal wear and tear. I have never been disappointed with what I have found and will continue to use Amsoil products.
    Bottom Line
    Yes, I would recommend this to a friend.

    Best Oil Second to None
    By  CRS,  a  Verified Buyer  from  Las Vegas  on  March 17, 2024
    Have used most top of the line OEM oils. After watching the true tests on youtube this oil is above OEM oil performance. When I started using Amsoil I can tell on every oil change the difference. Holds up better than the ones Ive used in over 20 years. Second to none!
    Bottom Line
    Yes, I would recommend this to a friend.

    A life saver for Direct Injection Turbo KIA motors!
    By  JOHN,  a  Verified Buyer  from  Free America AZ  on  March 14, 2024
    This is the only oil I found that met all the specs for my turbo D.I. KIA AND is guaranteed to prevent the silent knock that takes most of them out way before their time. I never need a drop between changes and I change the oil at 3.5 K miles just because I can.$75 bux for peace of mind. Love this stuff!
    Bottom Line
    Yes, I would recommend this to a friend.
