Product Highlights View Full Description

Formulated to outperform passenger-car/light-truck oils, AMSOIL Synthetic Small-Engine Oil protects against wear, deposits and oil consumption in over-worked, under-maintained small engines professionals rely on to make a living.

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).

Piston and rings

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 Synthetic Small-Engine Oil lasts longer than conventional oil, providing 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
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.

Comments about 10W-30 Synthetic Small Engine Oil:

I've used Amsoil in all my equipment for about 14 years. The longevity of the engines on our mowers is incredible! The mowers wear out long before the engines. And if we are so busy that we can't service the equipment exactly as scheduled, it's not a big deal. Amsoil Synthetic Small Engine Oil just doesn't break down.

Multiple motors

By 

from Rocky Point, NC

Verified Buyer

Comments about 10W-30 Synthetic Small Engine Oil:

I use Amsoil in my:
2008 M-Benz V-6 diesel (meets the 229.51 spec.)
2017 Subaru Forester 2.5 normally aspirated 4 cylinder boxer (0W-20 Signature Series);
2013 Yamaha 90 hp outboard (Marine oil.)
1999 Honda V-2 10kw generator (10W-30 Synthetic Small Engine Oil.)
pressure washer, and lawn mower (10W-30 Synthetic Small Engine Oil.)

I change oil in all these motors once a year, along with an Amsoil filter for the Forester.
I switched from Mobil products to Amsoil after I personally compared the specs for various motor oils, including the "Subaru" oil (actually Idemitsu Oil) and found that Amsoil matched or was better in most of the parameters on all the oils, particularly the NOACK value (for volatility or "boiling off" or evaporation.) I was especially interested in the 0W-20 values, since I had a chance to choose a specific oil to use in the new Forester for its life. I found that there was a huge NOACK difference between Amsoil and the Subaru/Idemitsu oil. No doubt that is why Subaru recommends a 6,000 oil change interval, and Amsoil Signature Series is at 25,000 miles. None of the other oils matched Amsoil's NOACK value. That comparison convinced me. At 500 miles I drained the Subaru/Idemitsu oil and switched to Amsoil Signature Series, and changed it again at 6,000 miles and am now on a yearly change cycle, since I average between 10,000 and 13,000 miles a year. Cheaper and better – a no brainer.
