    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.

    Bottom Line
    Yes, I would recommend this to a friend.

    20W-50 ZROD
    By  ALEX,  a  Verified Buyer  on  September 07, 2021

    Describe the issue

    First time using this oil and I'm glad I discovered this AMSOIL product. My Range Rover has a Rover V8 that really needs the Zinc additive to prevent excess wear. This seems to be doing the trick. I pulled the dipstick 1500 miles in and the oil still looks fresh and clear with only a slight darkening. I believe this is going to be my go to oil from now on!
    Bottom Line
    Yes, I would recommend this to a friend.
