PRODUCT DESCRIPTION

AMSOIL Formula 4-Stroke® Small Engine Oil (ASE) is a robust formulation designed for hot temperature, severe service operation of small engines where routine maintenance is often difficult or infrequent. It is formulated with premium synthetic base oils that exceed both 10W-30 multi-grade and SAE 30 straight-grade viscosity requirements. Unlike conventional SAE 30 motor oils, AMSOIL ASE has a naturally high viscosity index and does not contain paraffin (wax). It has a -38°F pour point and qualifies for SAE 10W, making it an "all season," multi-grade lubricant with a wide operating temperature range. As an SAE 30 weight motor oil, AMSOIL ASE provides outstanding protection for hot operating engines. Formula 4-Stroke® Small Engine Oil is a commercial grade lubricant that helps improve productivity and reduce maintenance costs through superior engine protection.

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.

Bobcats run hot, expensive to maintain. AMSOIL offers the new ASE as the solution.Resists Heat and Reduces Oil Consumption
AMSOIL engineered Formula 4-Stroke® Small Engine Oil to withstand the high temperatures of hard working engines. It effectively resists oxidation and oil vaporization to control oil thickening and reduce oil consumption. AMSOIL ASE lasts longer in service than conventional oils and keeps engines clean for peak operating efficiency.

Excellent For Transmission Systems
AMSOIL Formula 4-Stroke® Small Engine Oil is a shear stable formulation that contains no friction modifiers. It will not break down during rigorous mechanical activity, making it ideal for hydraulic or hydrostatic systems and chain cases. It is wet clutch compatible and designed to prevent clutch slippage in commercial or recreational transmissions. AMSOIL Formula 4-Stroke® Small Engine Oil protects gears and bearings during high-demand, commercial duty service.

Primary application is garden and lawn tractors.Superior Protection
Motor oil temperatures in automotive applications typically run around 210 degrees F, while oil temperatures in continually operating compact engines can easily top 300 degrees F. These elevated operating temperatures promote oil consumption and oil thickening and can significantly reduce the life of the oil. The combination of elevated oil consumption and infrequent maintenance can lead to low oil levels, placing further stress on the remaining oil, while reducing engine performance and increasing the chances for engine failure. Infrequent operation of these engines can be just as damaging. Acids generated during operation and water from condensation can build up in the oil during inactivity, promoting corrosion and rusting of internal engine components.

Recognizing the stress severe operating conditions place on small engine lubricants, many engine manufacturers are beginning to recommend synthetic oils for use over a broad range of ambient conditions. As a commercial grade lubricant, it meets the demands of homeowner, commercial and industrial applications, improving productivity and reducing maintenance costs through superior engine protection.

* “Air cooled engines run hotter than automotive engines.  The use of non-synthetic multi-viscosity oils (5W-30, 10W-30, etc.) in temperatures above 40*F (4*C) will result in higher than normal oil consumption.” -

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.

Mixing AMSOIL motor oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. Aftermarket oil additives are not recommended for use with AMSOIL motor oils.

Service Life
Follow the equipment manufacturer’s recommended drain intervals.

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.
