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
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,” multigrade 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
protection.

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.

Superior Protection
AMSOIL Formula 4-Stroke® Small Engine Oil is formulated with high levels of premium anti-wear
and detergent additive technology. It provides severe service protection of pistons, bearings and
gears and effectively neutralizes acids from combustion by-products prone to small engines. Anti-
rust additives further protect equipment during storage or infrequent use.

Mixing AMSOIL
AMSOIL Formula 4-Stroke® Small Engine Oil is compatible with conventional and synthetic motor
oils. 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.
