10W-30 Synthetic Small Engine Oil



Engine dependability is vital to running a profitable business, yet most small-engine oils we've tested are nothing more than re-labeled automotive oils, which are formulated with fuel economy in mind, not durability. That won't cut it. Compared to liquid-cooled automotive engines, small engines run hotter; operate under constant load; generate more oil-damaging contaminants; suffer from neglected maintenance and are exposed to dirt, rain, snow and other extremes. Simply put, they're far tougher on oil that most people think.

AMSOIL Synthetic Small Engine Oil isn't merely a re-badged automotive oil. Instead, we designed it from the ground up specifically for small-engine dependability. You can rest assured your engines are protected even during periods of extended use when there's no time for scheduled maintenance. It's built to solve the problems that plague small engines, including wear, power loss, oil consumption, stuck rings and valves, and harmful carbon deposits. It helps landscapers, contractors and other professionals get more work done and save money.

Excellent Wear Protection
AMSOIL Synthetic Small-Engine Oil is a shear-stable, high-film-strength formulation fortified with a heavy dose of zinc anti-wear additives. It does not thin out due to mechanical shear, ensuring a thick lubricating film. Its zinc chemistry forms a durable barrier that protects against metal-to-metal contact.

Piston and rings

Reduces Oil Consumption
In lab testing 10W-30 Synthetic Small-Engine Oil reduced oil consumption 61 percent compared to three leading 10W-30/SAE 30 motor oils**. Its heat-resistant synthetic base oils provide low volatility, excellent viscosity stability and strong oxidation resistance. Engines run longer between top-offs, providing peace of mind that they won't fail due to oil starvation and will run dependably in the harshest conditions.

Formulated for Power
Engine wear, carbon deposits, valve sticking and piston-ring sticking reduce engine power. Synthetic Small-Engine Oil prevents ring and valve sticking while helping eliminate carbon deposits from forming. As a result, engines produce maximum power throughout their service lives, helping you get more work done.

Extreme-Temperature Performance
Synthetic Small-Engine Oil's saturated molecular structure offers outstanding extreme-heat resistance. In addition, we've fortified the oil with potent anti-oxidant additives that provide further resistance to damaging heat. Its powerful detergent additives fight carbon, varnish and sludge to maximize engine life. In extreme cold, the oil's naturally high viscosity index and lack of paraffins (waxes) ensure it remains fluid and flows quickly, providing easier cold-weather starts and fast startup lubrication for reduced wear.

  • Extended drain intervals
  • Helps extend engine life
  • Rust-inhibited

Applications and Recommendations
AMSOIL Synthetic Small-Engine Oil is multifunctional and can be used in gasoline engines, off-road diesel engines and certain transmissions. It doesn't contain friction modifiers and meets JASO wet-clutch standards. It increases convenience and helps prevent misapplication.

Use the appropriate viscosity of Synthetic Small-Engine Oil in applications that require any of the following specifications:

  • API SL, SJ, SH, SG...(Gasoline)
  • API CD, CF (Diesel)
  • JASO MA/MA2, (Wet Clutch)

Use 10W-30 Synthetic Small-Engine Oil in small engines found in (not limited to) mowers (zero-turn, riding, stand-on, push), generators, power washers and other equipment that requires SAE 30 or 10W-30 motor oil, including those made by Briggs & Stratton*, Honda*, Kubota*, Kawasaki*, Kohler*, Tecumseh*, Robin*, Onan*, Wisconsin*, Powertrain*, Yanmar*, Linamar* and Vanguard.

Equipment types include maintenance equipment, tractors, lawn and garden equipment, compactors, pumps, light towers, log splitters, welders, cement mixers and trowels, skid-steers, excavators, rototillers and compressors.

COMPATIBILITY
AMSOIL Synthetic Small-Engine Oil is compatible with other conventional and synthetic motor oils. Adding other oils, however, will shorten the oil’s life expectancy of AMSOIL motor oils and reduce their performance benefits.

AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL Synthetic Small-Engine Oil.

SERVICE LIFE
AMSOIL Synthetic Small-Engine Oil is a long-life formulation that has repeatedly demonstrated its ability to safely exceed OEM drain intervals in the toughest conditions. Extensive severe-service testing proves its ability to provide service life of up to 200 hours/ one year, whichever comes first. It provides an extra measure of protection when equipment goes longer between oil changes than is recommended by the OEM.

    Great Oil
    By  Richard,  a  Verified Buyer  on  September 24, 2019
    I use this oil in all my 4stroke small engines. When I was introduce to this oil I was having a stuck oil ring problem with a riding lawn mower. Using this oil the problem went away saving me a teardown. I ran this mower 26 years before it went to the bone yard.

    Exceptional Product
    By  James,  a  Verified Buyer  on  September 23, 2019
    This small engine oil is exceptional! I maintain two gas lawn mowers and they both have new life due to this super oil! One for my home and the other on a lake property. The lake property is large and quite dusty ??

    I use Amsoil in every motor I have.
    By  Marc,  a  Verified Buyer  on  September 09, 2019
    I am using this in a riding mower and a push mower. After an oil change, the motors have run smoother and quitter then on the oil that was previously in it. The engines run a little cooler as well. The noise level has reduced and the motors have smoothed out. I am also running Amsoil in my Can Am and find the same results in that motor as well. Even my wife can hear the difference in the motors.

    I use this in every small engine I have.
    By  Dean,  a  Verified Buyer  on  September 03, 2019
    From weed eaters to mowers to generators, this is the only oil I use. These engines sit for days then get run hard for hours. AMSOIL protects the internals during both.
