    WOW! UNEXPECTED RESULTS
    By  MUGENIZER,  a  Verified Buyer  from  Vancouver  on  April 11, 2024
    I was using Pennzoil Ultra Platinum 0W-20 Full Synthetic for my Honda Pilot 2016 exl with 261K km in it. Obvious crackcase noise & lifter noise. Fuel consumption of 12.9 liters per 100km. Now with using Amsoil Signature Series 0W-20 Full Synthetic...noise in the crankcase & lifters are a lot less. My fuel consumption is now 11.8 liters per 100km. The engine run smoother than it was. I wish i've used Amsoil ever since. Now, i use it in every vehicle i own. I highly recommend this product.
    Bottom Line
    Yes, I would recommend this to a friend.

    Increased fuel mileage consistently.
    By  RICHARD,  a  Verified Buyer  from  Rockwell, NC  on  April 11, 2024
    I run the Signature series Amsoil in all my family vehicles. I change my daughters vehicles every year and the Ecoboost every 7,000 miles. I consistently see a 10% increase in interstate fuel mileage when converting over to Amsoil. Protect your investment with Amsoil products, you will be glad you did. A small cost to pay for peace of mind and protection. My Tacoma and my F150 all have over 250,000 miles and neither use more than 1/2 qt oil in 7,000 miles. The daughters cars typically log around 12,000 to 16,000 miles per year and most of their cars have over 200,000 miles. Switching to Amsoil typically results in less oil consumption due to the thermal stability alone. Great product.
    Bottom Line
    Yes, I would recommend this to a friend.

    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

    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.
