    Z-Rod 20w50
    By  JIM,  a  Verified Buyer  from  Mississippi  on  August 06, 2021
    Use in my Street Rod, ZZ-4 increased oil pressure at idle some 15 lbs. Have previously used in a Corvette that I road raced, great product. After engine tear down and really beating on the car engine 4000-5500RPM's for some 15 races no bearing wear what so ever dont wasted your $$ on other products, firm believer in AMSOIL
    Bottom Line
    Yes, I would recommend this to a friend.
