Delivers commercial-grade protection and outperforms conventional oils. Tough formulation protects against wear, heat and carbon deposits. Helps maintain power and promotes long engine life. Specifically designed for maximum equipment dependability. Service life up to 200 hours.
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.
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.
Been using this for years and have not had any issues
Bottom Line
Yes, I would recommend this to a friend.

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.
I have a 1999 Suzuki Carry, 660cc motor in the little fella, we use this all the time. Also use it in the log splitter, pressure washer, ATV, etc etc.
No problems yet. Like that it comes in xxW-40, small engines always run hot, in the hottest of conditions.
Bottom Line
Yes, I would recommend this to a friend.
