    Z-ROD Review
    By  ERIC,  a  Verified Buyer  from  O'Fallon IL  on  December 15, 2021

    Describe the issue

    Z-ROD is exactly what I need to keep my original 1966 V8 going strong. It spends a lot of time in storage and Z-ROD is exactly what I need to fight moisture/rust and fire it up when bringing it out to drive. The Zinc additive is the best part and protects my old engine components. Wouldn't buy any other oil!
    Bottom Line
    Yes, I would recommend this to a friend.

    Really great in my Supercharged Viper
    By  STEVE,  a  Verified Buyer  on  November 17, 2021

    Describe the issue

    I changed the Viper from Mobil 1 and immediately saw a difference. The car has both engine coolant temp and oil temp gauges. With Mobile 1, they were always within a couple degrees of the same. With the Amsoil, the engine oil dropped 6 to 10 degrees. The engine makes about 825 HP. The Mobile 1 was always discolored upon oil change. The Amsoil is still red when I change it, at twice the miles.
    Bottom Line
    Yes, I would recommend this to a friend.
