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.

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 5ystems
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.

Applications and Recommendations
AMSOIL Formula 4-Stroke® Small Engine Oil is recommended for use wherever SAE 10W-30 or SAE 30 oil is specified in gasoline or diesel engines, transmissions, hydraulics and chain cases that require the following:

  • API SL, SJ, SH, SG...(Gasoline)
  • API CF, CD (Diesel)
  • JASO MA (Motorcycle Wet Clutch)

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.
