Overview

YIDUN API SL fully synthetic gasoline engine oil is developed and manufactured by Baoding Muhai Lubricating Oil Import & Export Co., Ltd. Formulated with premium synthetic base stocks and high-performance multi-functional additives including detergent, anti-wear and antioxidant agents through advanced blending technology. API SL is high-performance grade for gasoline engine oil. It quickly forms a tough and stable lubricating film on engine metal friction surfaces to protect equipment under frequent start-stop, long continuous operation and variable temperature working conditions. The 4L large-capacity pail is ideal for regular vehicle maintenance and bulk export procurement, widely used for all kinds of gasoline-powered equipment.

Key Features

✅ Long-lasting Engine Protection & Wear Reduction High-performance anti-wear formula creates high-strength oil film on pistons, crankshafts, camshafts and other components. It isolates metal contact, reduces wear during cold starts and extends overall engine service life, supporting long-time operation under medium and heavy loads.

✅ Excellent High-Temperature Oxidation Resistance & Deposit Control Superior thermal stability and oxidation resistance. It resists thickening and performance degradation under high temperature. Detergent-dispersant additives capture combustion residues, reducing carbon deposits, sludge and varnish buildup, keeping engine internals clean and oil passages unobstructed.

✅ Reduced Friction, Improved Power & Fuel Economy Optimized friction coefficient cuts internal power loss of the engine, delivering strong and smooth power with sensitive throttle response. It reduces engine energy consumption and optimizes fuel consumption to save long-term operating costs.

✅ Great Seal Compatibility to Prevent Oil Leakage The formula is well compatible with engine rubber seals. It slows aging and hardening of gaskets, lowers the risk of oil leakage and maintains stable oil pressure.

✅ Multiple Viscosity Grades for Various Climates & Conditions Available in 0W-30/40, 5W-30/40, 10W-40, 15W-40, 20W-50. Suitable for cold, temperate and hot tropical working environments.

✅ 4L Large Capacity Pail with Handle Equipped with ergonomic handle for easy pouring. Standard volume for vehicle maintenance, perfect for bulk orders of auto repair shops and fleets.
