    Best oil I’ve used. Worth it
    By  CHRIS,  a  Verified Buyer  from  New York  on  June 28, 2022
    Been using this oil in my ‘18 Chevy Malibu since 15k miles and the car now has over 95k and the engine still runs like new. Definitely cheap and worthwhile insurance for anyone looking to maintain their engine for a long time.

    110k and driving
    By  Richard,  a  Verified Buyer  from  Illinois  on  June 28, 2022
    When I bought My 2011 300 3.6 Penstar I immediately switched to Amsoil now with 110k miles she runs like new. I swapped my rocker arms and lifters because of a slight ticking not associated with the fuel injectors, The inside of the motor was clean as a whistle and the one rocker had the slightest of damage barely noticeable. the remaining valvetrain was imaculent. I would recommend this product for your Penstar engines
    Bottom Line
    Yes, I would recommend this to a friend.

    Impressed with the longevity and quality of all AMZOIL oils
    By  BERNIE,  a  Verified Buyer  from  Seattle  on  June 26, 2022
    I have used AMZOIL filters/oil/and bypass systems in all my trucks, and most my cars/motorcycles. My '86 Jeep Comanche is going on 320K, my 2008 is going on 210K, I just converted my 2019 Alfa to AMZOIL and got a slightly longer filter to supersede the original/add extra oil capacity since a bypass won't fit. I hope to get long, trouble-free life out the Alfa as I have my other vehicles.

    Bad sales tactics
    By  WESLEY,  a  Verified Buyer  on  June 26, 2022
    Good product bad sales tactics. Amsoil always sends me the promotional codes after I have placed an order. When I try to use the promotional codes on later orders it tells me those promotions have expired. Pretty shady if you ask me.
    Bottom Line
    Yes, I would recommend this to a friend.

    Signature 5-20 Synthetic oil, Never Use Anything Else
    By  GENE S.,  a  Verified Buyer  from  Lancaster, CA  on  June 25, 2022
    The only oil I've used in my 2015 Jeep Wrangler. I've checked and I have the same cyclinder compression and fuel mileage I did when our Jeep was new. Mainly city and short trip driving and 56K miles. High heat in summer 115 degrees plus and never a whimper whether idling or working hard.
