    By  ROY,  a  Verified Buyer  from  Sapulpa Ok  on  April 28, 2024
    Used this oil for the hydraulics in my SCAG riding lawnmower. The higher zinc is better for that application. I only use ANSOIL in all my applications.

    Z-ROD 20w-50 the Best!
    By  MONTE,  a  Verified Buyer  from  California  on  January 14, 2024
    Using this oil in my vintage English car. Wanted a high zinc oil to help mitigate wear on start-up since the car sits for a week or two between trips. The combination of extra zinc with a fully synthetic base is great. The start-up and running protection of this oil are fantastic.
    Bottom Line
    Yes, I would recommend this to a friend.
