    Best high zinc motor oil
    By  Russ,  a  Verified Buyer  from  CA  on  September 09, 2023
    Amsoil ZRod is the best, high zinc content motor oil that I've found. I used Amsoil Break-In Oil first, and now I'm using ZRod in my freshly rebuilt 1937 Oldsmobile straight 8.
    Bottom Line
    Yes, I would recommend this to a friend.

    High quality stuff
    By  JOEL,  a  Verified Buyer  from  BC Canada  on  June 15, 2023
    I like the fact it has just the right amount of ZDDP so I don't have to mix anything and I know my new flat tappets are protected. This is the best quality stuff out there and only the best goes into my car.

    Z-Rod recommendation
    By  Arnold,  a  Verified Buyer  from  MI  on  January 23, 2023
    I have been using the Z-ROD 10w-30 oil in my 1969 Mustang/351Windsor for several years and it keeps the engine very clean and gets good oil pressure in excessive heat at highway speeds. I am switching to the 10W-40 this spring because I'm doing more extended traveling miles and tend to run over 100 miles at 65+ mph before I give it a break.
    Bottom Line
    Yes, I would recommend this to a friend.
