• Medium & High Ash All-Round Formula | Optimized for High-Pressure Common Rail + EGR

• Formulated with imported medium & high ash additives to tackle high soot, temperature and pressure of China V/Euro V engines with high-pressure common rail and EGR systems, delivering full protection for engines and EGR components. Designed for China V/Euro V engines and compatible with China IV and older models.

• Note: Use CK-4 low-ash engine oil for vehicles fitted with DPF.

• Comprehensive Protection | Longer Engine Service Life

• High-performance composite dispersants encapsulate and disperse soot rapidly, preventing sludge, blocked oil passages and abrasive deposits. Its oxidation resistance is 72% higher* than API CI-4 standard, resisting high operating temperature and abnormal viscosity change to extend oil service life. Specially formulated sulfur-phosphorus anti-wear agents form robust oil films on precision parts to reduce wear under extreme working conditions.

• Stable Oil Pressure | Reliable for Heavy Loads

• Compton 2nd-Gen Pressure Balancing Technology ensures steady oil pressure and consistent power output. Premium imported additives slow oil aging and viscosity degradation. US-made viscosity index improvers effectively prevent oil pressure drop caused by temperature variation and viscosity loss.

• Cost Efficiency | Lower Total Operating Costs

• Premium base oils and imported additives reduce oil top-up frequency and consumption. Outstanding soot resistance mitigates component wear. Optimized formula improves fuel economy (15W-40 grade).
