    By  Adan,  a  Verified Buyer  from  CA  on  October 16, 2023

    An excellent motor oil
    By  ROBERT ,  a  Verified Buyer  from  Sauk Rapids, MN  on  October 15, 2023
    This is a great performing oil. Enables my car to start in sub zero temperatures. I feel I have great protection too and get slightly better mpg. Only reason for four stars instead of five is the cost. It's getting expensive. I have used Amsoil products since 1998 and have been very satisfied.
    Bottom Line
    Yes, I would recommend this to a friend.

    Hands down the best
    By  ANTHONY,  a  Verified Buyer  on  October 12, 2023
    This oil is amazing, my car runs so much better with this. It is a little pricey but worth it. Since it is expensive I decided to switch from it to the dealership brand oil in my Corolla since it was a few dollars a quart cheaper. I figured since it was Toyota brand it’s gotta be good right? I could tell the difference immediately with the Toyota brand oil. The RPMs ran higher at idle and the engine made a clattering noise when I would accelerate. I switched back to Signature series in 1,000 miles. Everything quieted down immediately. When I pull up to stop lights you can’t hear the engine at all, no more clattering when I accelerate. I’m thoroughly convinced that this oil is the best there is.
    Bottom Line
    Yes, I would recommend this to a friend.

    I will never use any other product(s) in my vehicles!
    By  ERIC,  a  Verified Buyer  from  Michigan  on  October 11, 2023
    My vehicle engines (2011 F-250 6.2 gasser & 2008 Harley Ultra Classic) run smoother, cooler and quieter using Amsoil products. I will never use any other lubricants other than Amsoil in any of my vehicles. And when I do oil changes, I get every drop back!
    Bottom Line
    Yes, I would recommend this to a friend.

    Mustang GT 2020
    By  JUAN,  a  Verified Buyer  from  Austin  on  October 11, 2023
    Best oil in the market hands down. Worth every penny due to the benefits of this oil. I used to use Mobil 1 on my car and it just didn't feel right. Then I gave amsoil a try and never looked back. My cars engine feels so much better than before.
    Bottom Line
    Yes, I would recommend this to a friend.

    Expensive but Very Good
    By  LARRY,  a  Verified Buyer  from  Millington, TN  on  October 11, 2023
    Been using Amsoil oil in my vehicles for years. I had to replace the timing chain and related components on a 75,0 00 mile Honda Accord Sport, which required the timing and valve covers removal. I was shocked at how clean the engine internals were. No sludge or residue anywhere. Looked like a new engine. That sold me on Amsoil Signature motor oil. Started using the Amsoil 0-20W Signature oil because it was the highest rated oil for a direct injection engine that I could find, and it sure paid off.
    Bottom Line
    Yes, I would recommend this to a friend.
