    Zeroturn mower
    By  DOUG,  a  Verified Buyer  from  Stilwell  on  June 27, 2025
    I have a Honda engine powered Zero turn with approximately 1200 hours. It was purchased 4-26-2003. I have been using this oil for about 10 years. I use no oil between oil changes. There is no smoke on start-up or while running while mowing. I haven't sent oil sample to be tested because I don't see any kind of wear issues. The next door neighbor is now using it in their new Z-turn mower with a Kawasaki engine. I am very happy with this oil and highly recommend it!
    Bottom Line
    Yes, I would recommend this to a friend.
