EXCELLENT WEAR PROTECTION

  • Shear-stable, high-film-strength formulation fortified with a heavy dose of zinc anti-wear additives.

FORMULATED FOR POWER

  • Prevents ring and valve sticking while helping eliminate carbon deposits.

    All lawn equipment
    By  ANTHONY J.,  a  Verified Buyer  from  Florida   on  November 08, 2024
    We have been using this oil in all our outdoor equipment right after 6 hour break in. We generally change it every 100 hours because of Florida heat and sandy conditions I can honestly say everything runs quieter and more smoothly. We just purchased a champion 12,000 watt generator after 5 hours we put this oil in it and after the hurricanes we have over 90 hours on it and we didn’t need to add any the plus side we noticed the generator was a little more quiet
    Bottom Line
    Yes, I would recommend this to a friend.

    A Dependable Oil.
    By  DAVID,  a  Verified Buyer  from  Indiana  on  June 18, 2024
    I run this oil in my Hustler Raptor SD with a Kawasaki V-twin engine. This is my 10th season mowing with it. Last season it started smoking a little at start up. I had always ran Kawasaki oil in it. This season I decided to run AMSOIL in it. The smoking at start up stopped, and the mower seems to be running smoother and quieter then it was in the past, so far it's been a great oil.
    Bottom Line
    Yes, I would recommend this to a friend.
