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 Small Engine Oil 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 Small Engine Oil 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 Small Engine Oil 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.
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 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
for use with AMSOIL motor oils.
AMSOIL Formula 4-Stroke 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
