EXCELLENT WEAR PROTECTION

  • Shear-stable, high-film-strength formulation fortified with a heavy dose of zinc anti-wear additives.
  • Does not thin out due to mechanical shear, ensuring a thick lubricating film for maximum wear protection.
  • Zinc chemistry forms a durable barrier that protects against metal-to-metal contact.

REDUCES OIL CONSUMPTION

  • Reduced oil consumption 61% in lab testing compared to three leading 10W-30/SAE 30 motor oils.1
  • Heat-resistant synthetic base oils provide low volatility, excellent viscosity stability and strong oxidation resistance.
  • Helps engines run longer between top-offs, providing peace of mind they won’t fail due to oil starvation and will run dependably in the harshest conditions.

FORMULATED FOR POWER

  • Prevents ring and valve sticking while helping eliminate carbon deposits.
  • Reduces piston-ring and cylinder wear for maximum engine compression.
  • Helps produce maximum power throughout their service lives, helping you get more work done.

See the product data sheet for full details.

¹Based on 125-hour lab tests of small engines using AMSOIL 10W-30 Synthetic Small-Engine Oil and three leading 10W-30/SAE 30 motor oils.

    Commercial use
    By  SCOTT,  a  Verified Buyer  from  Alabama  on  September 22, 2022
    I use this in my commercial mowers. Hundreds of ours so far. I personally would not go over 100 hours on any oil unless you have a separate oil resuvuir. All in all, this oil takes a beating and has I think made up the difference in price from cheaper oils.
    Bottom Line
    Yes, I would recommend this to a friend.

    Small Engine SAE 10-40
    By  REX,  a  Verified Buyer  on  June 24, 2022
    I've been using Amsoil products for years and have not been disappointed with their performance. My JD 318 and now Kubota Z422 use Small Engine Oil. I think this oil has permitted the JD 318 to operate without a mechanical issue, even under some hard use. Since the Kubota is new it should last for years to come.
    Bottom Line
    Yes, I would recommend this to a friend.
