    Top quality in my mind!
    By  DALE,  a  Verified Buyer  from  Beamsville Ontario Canada   on  April 05, 2024
    I understand the importance of quality oil, it’s dirt cheap in my mind for the protection it offers. I’m extremely fussy and do all my own service. Worked as a mechanic in a Ford Dealer then moved to the Collision industry as a Painter/Prepper/Trainer with DuPont.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  STEVEN,  a  Verified Buyer  from  Florida  on  April 05, 2024
    My 2018 Chrysler Pacifica with 51,000 miles calls for 0W-20 oil but a technician at a Chrysler dealership told me if I switched to Amsoil 5W-20 Synthetic oil my engine would not only preform better but the cold start rattle in the mornings would be gone. He was right. This is an excellent product and I highly recommend it
    Bottom Line
    Yes, I would recommend this to a friend.

    Ayuda a silenciar y proteger
    By  JOSE,  a  Verified Buyer  from  Austin, TX  on  April 04, 2024
    Excelente producto. Aplique 1 quart de este producto junto al signature de 0w-20 en el corolla 2017 de mi mama con 110k millas y esta super contenta, me dice que acelera mas rico y esta mas callado. Muy contento con estos resultados. El motor 1.8L de Corollas requiere 4.4 Quarts para el verano aplicare 2 quarts de este 0w-30 con 2.4 quarts de 0w-20.
    Bottom Line
    Yes, I would recommend this to a friend.

    Betrayal
    By  KEVIN,  a  Verified Buyer  on  April 03, 2024
    Amsoil has betrayed its marketing strategy by going to advertising; I can't hardly watch a you tube video without an Amsoil ad at the beginning - even worse the ad doesn't tout the benefits of its products. The cost of advertising has raised the price of Amsoil products significantly!
    Bottom Line
    Yes, I would recommend this to a friend.

    Makes a 2019 Ridgeline even better
    By  JEFF,  a  Verified Buyer  from  Pennsylvania   on  April 03, 2024
    I just bought a 2019 Honda Ridgeline with 67000 miles. I did the transmission within a week to discover that it hadn't been done yet. I have a thousand miles on it now, and I'm going to change it again when there is a dry weekend to rotate the older oil out further. I look forward to this truck lasting as long as I will ever need it. Shifting is smoother, and Shifting RPMs have dropped. Amsoil is awesome as ever!
    Bottom Line
    Yes, I would recommend this to a friend.

    Nothing Better I bet ya!!!
    By  MICHAEL,  a  Verified Buyer  from  Kentucky   on  April 01, 2024
    I've not found a better product flat out! If you are a DIY person you will easily be able to tell the difference just by feel alone. I run this in both of my Vehicles and I've had ABSOLUTELY NO PROBLEMS, Motors are happy, they run cooler & more freely. I bought once and I'm a lifetime customer. If tests are what you like to watch on YouTube watch Project Farm and he tests this oil compared to other leading brands there is no comparison Amsoil currently is the best on the market. I'm not paid or compensated in any way for this review.
    Bottom Line
    Yes, I would recommend this to a friend.
