    Really awesome stuff
    By  KEITH,  a  Verified Buyer  from  Ohio  on  November 26, 2024
    Listened to a deep dive factory tour with the truck show podcast, sounded amazing and American made for sure. Bought an oil change kit for my brand new 2024 Silverado 2500HD and it’s not like it was going to change anything being a new truck but I have noticed increased mpg and smoother operations already.
    Bottom Line
    Yes, I would recommend this to a friend.

    La meilleure!
    By  MICHAEL,  a  Verified Buyer  from  Quebec Canada  on  November 25, 2024
    Mon moteur roule beaucoup plus doux malgré ses 200 000km. Il ne sent plus l'huile brûlée lorsque je remorque et en bonis la consommation d'huile entre les vidanges a chutée de moitié!

    Best oil hands down
    By  GARY,  a  Verified Buyer  from  New Jersey   on  November 24, 2024
    This oil definitely is everything they claim. I started using Amsoil in my Motorcycle ( Harley Davidson). In air cooled bikes oil is everything. And now use in everything I own. Never a concern with upper valve train quiet operation and increased free rpm. In my 5.7 liter hemi very noticable the difference in valve train quietness just like the Harley and Indian motors. Again you can't go wrong.
    Bottom Line
    Yes, I would recommend this to a friend.

    all engine oils
    By  DANNY,  a  Verified Buyer  from  Georgia  on  November 24, 2024
    I started using AMZOIL about 2 years ago, and I use 3 different types depending on which vehicle. I am a carrier technician and I am in my 50th year. I'm a believer in proper service and use this on all my vehicles. I started that after watching Gail Banks videos. Keep up the good work. Danny

    Signature oil
    By  JOHN,  a  Verified Buyer  from  Alpena mi  on  November 23, 2024
    My wife and I have owned an auto repair shop for 38 yrs. We have always been about quality. Now that we are retired, we want to give our vehicles the best we can. We are high mileage drivers. We use Amsoil products only. Of course nothing is an absolute guarantee. But knowing our vehicles are getting the best we can give is a real piece of mind. Thank you Amsoil for giving us your very best. Very very satisfied customer.

    Excellent oil
    By  OSCAR,  a  Verified Buyer  from  Maryland  on  November 21, 2024
    What do you say about an engine oil, I’m not a petroleum chemist? I only use Amsoil engine oil in all my mobile equipment. After putting hundreds of thousands of miles on my cars and seeing the condition of the valve train, or cylinders when I have an oil pan dropped to change a rear main seal, for over 30 years it’s no contest. I don’t care what viscosity is required, if it’s Signature Series I’m confident in the protection. I don’t believe there’s any better.
    Bottom Line
    Yes, I would recommend this to a friend.

    Fantastic oil
    By  IAN,  a  Verified Buyer  from  Edmonton, AB  on  November 21, 2024
    I have been using Amsoil on my Ford Edge since the first oil change & I won't use any other oil. I love the pour point for this oil, the OEM oil had difficulty starting at -12C after sitting in a detached garage overnight. With the Amsoil it never had any problems starting even without being plugged in. Even with temperatures dropping to -38 outside.
    Bottom Line
    Yes, I would recommend this to a friend.
