    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.

    By  Joel,  a  Verified Buyer  from  Alabama  on  September 27, 2021

    Describe the issue

    I started running Amsoil when I purchased my first Chevy 2500 with the Duramax engine in 2007, I became a Preferred Customer and when I need oil, Amsoil is what I buy, run the racing oil in my 2 camaro Hot Rods, run the Signature Series oil in my Honda Accord work car, purchased a new 2020 GMC Denali 2500 with the Duramax and at 2500 miles changed it to Amsoil Diesel Oil, also run the racing Transmission Fluid in my 2 hot rods and my old Duramax and will be changing the transmission fluid in my new truck in a few more miles, also run the Amsoil gear oil my hot rods and want to change my truck gear oil to Amsoil soon, have had no problems and hope that the Amsoil is going to make everything last longer, also run Amsoil filters on everything

    Z-Rod, Great product
    By  Werner,  a  Verified Buyer  from  Chateauguay Qc.  on  September 15, 2021

    Describe the issue

    I started using Z-Rod motor oil in my 68 Charger last year. I have tried many other motor oils in my 440 engine. These big block engines create a lot of heat and are pretty tough on oil. With the Z-Rod oil, I find my engine runs cooler and just seems to run so much better. It's not uncommon for big block Chrysler engines to be topped up with oil every so often but with this oil, my engine doesn't require a top up nearly as often. This is my second case I've ordered and will run nothing else in my classic car.
    Bottom Line
    Yes, I would recommend this to a friend.
