Synthetic Formula 4-Stroke 10W30/SAE30 for Commercial Grade - One Quart
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.
