    Engine Runs Cooler w/ Better Oil Pressure
    By  THOMAS,  a  Verified Buyer  from  Brier Washington  on  May 13, 2022
    AMSOIL Z-Rod 20W-50 allows my 406 blown engine to run smoother, cooler and with better oil pressure. I will now only use this oil in this engine. This engine is used a 41 Willys street rod. The engine now idles better and I feel is a more healthier oil to use in this performance engine.
    Bottom Line
    Yes, I would recommend this to a friend.
