10W-30 SAE 30 PRODUCT DESCRIPTION

Using a high-quality small-engine oil has a direct effect on efficiency and profitability. Over time, wear and deposits rob small engines of power, reducing productivity. High heat can cause oils not formulated for severe service to boil off, leading to increased oil consumption, forcing the work crew to continually top-off the oil. AMSOIL Synthetic Small-Engine Oil is a tough formulation designed to preserve engine power while fighting oil consumption, helping professionals work more efficiently and save money on maintenance.

Fights Power Loss

Continuous severe-service operation accelerates wear and leads to harmful deposits that can stick rings and valves, robbing the engine of power. Power loss means less productivity and more maintenance. Synthetic Small-Engine Oil is a tough synthetic oil chemically engineered with anti-wear additives and heat-resistant anti-oxidants that protect pistons and bearings. After 500 hours of severe-service lab testing, AMSOIL 10W-30 Synthetic Small-Engine Oil virtually eliminated wear and deposits, helping preserve engine power and ensure productivity (see image).

Reduces Oil Consumption

Commercial-grade small engines run hot, with oil temperatures reaching 250ºF and higher. High heat causes standard-service oils to vaporize and exit the crankcase vent, leading to increased oil consumption. Heat also breaks down oil and forms deposits that lead to piston-ring sticking. Stuck rings fail to seal the combustion chamber and keep oil from entering and burning. As a result, workers must diligently check and top-off the oil to ensure the engine is protected, wasting time and money. AMSOIL Synthetic Small-Engine Oil’s heat-stable synthetic base oils withstand extreme heat better than other oils. In lab testing 10W-30 Synthetic Small-Engine Oil reduced oil consumption 61 percent compared to three leading 10W-30/SAE 30 motor oils**. It keeps engines clean for peak efficiency and reduced maintenance.

Long Service Life

On busy job sites, equipment maintenance can easily be delayed or overlooked completely. If using standard-service motor oils, high rates of oil consumption can leave the engine unprotected for extended periods, and it’s only a matter of time before catastrophic wear sets in. AMSOIL 10W-30 Synthetic Small-Engine Oil lasts longer than conventional oil, providBobcats run hot, expensive to maintain. AMSOIL offers the new ASE as the solution.ing peace of mind that engines are protected, even when maintenance is delayed.

  • Preserves engine power
  • Helps cut maintenance costs
  • Fights heat and deposits

Applications and Recommendations

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, 5W-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. Mixing AMSOIL motor oils with other oils, however, will shorten the oil’s life expectancy and reduce the performance benefits.

Aftermarket oil additives are not recommended for use with AMSOIL motor oils.

SERVICE LIFE

 

Primary application is garden and lawn tractors.

AMSOIL Synthetic Small-Engine Oil is a long-life formulation that can last longer than conventional petroleum oils. It provides an extra measure of protection when equipment typically goes longer between oil changes than is recommended by the equipment manufacturer. Due to wide variances in operating conditions and maintenance practices, AMSOIL recommends extending drain intervals when monitored by oil analysis or following the equipment manufacturer-established drain intervals.

How can a multi-viscosity work as a mono-viscosity?

Please see the Technical Service Bullitin Titled: Viscosity of Monograde and Multigrade Oils on this very subject why our 10W30/SAE-30 is the best for your specific needs calling for the old streight weight.

Tecumseh 150 hour endurance test

Tecumseh 150 hour endurance test. How well does your oil hold up at a constant 290 degrees?

Developed within the compact engine industry, the Tecumseh 150-hour endurance test measures a lubricant’s ability to function in continuous operation applications and severe operating conditions common to engines in the field. Operating speed is maintained at a constant 3,200 RPMs, while average oil temperature is 283 degrees F, average intake air temperature is 103.5 degrees F, average cylinder head temperature is 570.9 degrees F and average exhaust temperature is 1256.4 degrees F.

LETTERS TO THE EDITOR

Small-Engine Drain Intervals

With the performance and expectations of AMSOIL products, there seems to be something missing in the small engine interval recommendation. Why only the OE drain interval? I have numerous small engine customers who put who put many hours a year on their air compressors, water pumps, generators, welders, etc. With my personal experience and testing over the years, I am convinced it would be possible to go three to five times the OE drain interval in these applications. We have vehicles going up to eight times the OE drain interval, so why not more on small engines? Hopefully, this is possible in certain applications. Thanks for all the great products.

Orlie Yoder

AMSOIL: Because small engines are often air-cooled and power a wide variety of applications with different operating conditions and sump sizes, it is impossible to recommend an extended drain interval. Instead, recommendations are made for the lowest common denominator or worse case scenario. Many applications you mentioned can go beyond OEM drain interval recommendations based on oil analysis, but they must be controlled and monitored.
