Engineered for fleets and commercial vehicles, this oil is the go-to solution for operators who demand reliability from their heavy-duty truck engine oil.

Advanced Protection for Long-Lasting Engines

Powered by a high-performance synthetic formula, API CI-4 Engine Oil reduces friction by 25% compared to mineral oils, forming a robust protective layer that minimizes wear on critical components like camshafts and bearings. This extends engine life by up to 20% and cuts maintenance costs, ideal for heavy-duty trucks logging thousands of kilometers. Its shear-stable viscosity ensures consistent lubrication in extreme temperatures (-30°C to +150°C), delivering dependable performance whether hauling heavy loads or navigating harsh climates.

Emission Compliance & Durability

CHENYANG’s formula supports modern emission systems like SCR and EGR, helping engines meet China National V/IV and API CI-4 standards by reducing NOx and PM emissions. The low-ash, high-detergency blend prevents soot and sludge buildup, protecting aftertreatment devices and maintaining engine cleanliness for optimal performance. High-temperature stability resists oxidation, ensuring viscosity and film strength under prolonged stress, while anti-wear additives like ZDDP reduce load-related wear by 30%, making it a durable choice for demanding operations.
