Overview

YIDUN API SN 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 advanced multi-functional additives including detergent, anti-wear and antioxidant agents through advanced blending technology. API SN premium grade gasoline engine oil quickly forms a tough and stable lubricating film on engine metal friction surfaces to handle severe working conditions such as frequent start-stop, long-distance high-speed driving and alternating high & low temperatures. The 4L large-capacity pail is the standard volume for vehicle maintenance, ideal for bulk export orders of auto repair shops and fleets, suitable for various gasoline-powered machines.

Key Features

✅ Long-lasting Engine Protection & Wear Reduction Advanced anti-wear formula creates high-strength oil film on pistons, crankshafts, camshafts and other components. It isolates metal contact, greatly reduces cold-start wear and extends engine service life for long-time medium & heavy load operation.

✅ Superior High-Temperature Oxidation Resistance & Deposit Control Excellent 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 to keep engine internals clean and oil passages unobstructed.

✅ Reduced Friction, Boosted Power & Improved Fuel Economy Optimized friction coefficient cuts internal power loss of the engine, delivering smooth and strong power with sensitive throttle response. It reduces engine energy consumption and saves fuel cost over long-term use.

✅ Excellent 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.
