AMSOIL 100% Synthetic Small-Engine Oil

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.

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 automo- tive 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, harmful carbon deposits and stuck rings and valves. It helps landscapers, con- tractors and other professionals get more work done and save mone

Excellent Wear Protection

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

Reduces Oil Consumption

In lab testing, AMSOIL 10W-30 Synthetic Small-Engine Oil reduced oil consumption 61 percent compared to three leading 10W-30/SAE 30 motor oils.¹ Its heat-resistant syn- thetic base oils provide low volatility, excellent viscosity stability and strong oxidation resistance. 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

Engine wear, carbon deposits, valve sticking and piston-ring sticking reduce engine power. AMSOIL Synthetic Small-Engine Oil prevents ring and valve sticking while help- ing 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

AMSOIL Synthetic Small-Engine Oil’s saturated molecular structure offers outstand- ing extreme-heat resistance. In addition, we’ve fortified the oil with potent antioxidant 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.

APPLICATIONS

Use the appropriate viscosity of AMSOIL 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 5W-30 Synthetic Small-Engine Oil in small engines found in (not limited to) snowblowers, generators, power washers and other equipment that requires SAE 30 or 5W-30 motor oil, including those made by Briggs & Stratton,* Honda,* Kohler,* Champion,* Generac,* Toro,* Ariens,* Troy Bilt,* John Deere,* MTD* and Husqvarna.*

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.*

Use 10W-40 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 10W-40 or 15W-40 motor oil, including those made by Kubota, Kawasaki, Robin, Onan, Linamar and Vanguard.

Use 15W-50 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 50, 10W-50 or 15W-50 motor oil.

COMPATIBILITY

AMSOIL Synthetic Small-Engine Oil is compatible with other synthetic and conventional motor oils. Adding other oils, however, will shorten the 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 or 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.

GUARANTEED PERFORMANCE

Like our products, the AMSOIL Limited Warranty is built with an extra measure of protection. While some other oil companies guarantee their products only until you reach a specified mileage, we don't place restrictions on our warranty coverage based on total vehicle miles.

Plus, AMSOIL products are Warranty Secure, keeping your factory warranty intact. They are high-performance replacements for vehicle/equipment manufacturer-branded products.
