COPTON NG30
Enhanced Gas Engine Oil
Specially formulated for gas engines operating under severe conditions, meeting specifications of Weichai, Xichai, Sinotruk, Yuchai and other mainstream gas engines.
Stable Oil Pressure & Strong Power
2nd-Gen Pressure Balancing Technology ensures steady oil pressure and sustained power. Equipped with US-imported PARATONE® viscosity index improver featuring 24 SSI shear stability for long-lasting consistent viscosity.
Reliable High-Temperature Protection for Heavy-Duty Use
Reinforced oxidation and nitration resistance inhibits sludge formation and rapid oil degradation at high temperatures, maintaining stable viscosity and oil pressure.
15W/40: Excellent viscosity-temperature performance for use across a wide range of climates.
20W50: High viscosity, ideal for heavy-duty gas engines with larger clearances or running in high-temperature environments.
Superior Anti-Wear & Cleaning Protection
Proper ash content reduces valve wear, extends service life and prevents spark plug clogging. It effectively protects cylinders, crankshafts, camshafts and followers against wear, lowering breakdown risks and prolonging engine life. Outstanding detergency and dispersancy eliminate sludge and deposits to keep the engine clean.
