Synthetic Technology

RECOMMENDED APPLICATIONS

High-Ash & High-Viscosity Formula | Ideal for Heavy-Duty Operation
Its high ash content and viscosity form an auxiliary protective film on cylinder walls, compensating for degraded sealing and enlarged clearances in aged engines to cut blow-by and oil consumption. It delivers comprehensive protection for traditional turbocharged heavy-duty diesel engines.
Anti-Wear, Deposit Control & Anti-Corrosion
Superior anti-wear performance reduces component wear and extends engine service life. Excellent detergency, dispersancy and soot control prevent sludge and carbon buildup to keep the engine clean. Effective acid neutralization protects against acid corrosion.
Stable Oil Pressure for Heavy Loads
Compton 2nd-Gen Pressure Balancing Technology maintains steady oil pressure and consistent powerful output. Premium additives slow oil aging and abnormal viscosity changes.
Application
Suitable for traditional turbocharged diesel engines requiring API CF-4 or lower grade lubricants.
15W-40: Great viscosity-temperature performance for wide-ranging climates.
20W-50: High viscosity, perfect for heavy-duty engines with large clearances or running under high temperatures.

CHINA VI EMISSION STANDARD

Suitable for traditional engines requiring CF-4 and below grade diesel engine oil.
