    FIRST RATE!
    By  CARL,  a  Verified Buyer  from  Willowick Ohio  on  May 20, 2025
    I've been using this small engine oil for years. Cost's a little more but it's a lot cheaper than a engine cylinder rebuild. Consistency holds up like no other. You get what you pay for folks and Amsoil is #1 in my book.
    Bottom Line
    Yes, I would recommend this to a friend.
