High-efficiency engine detergent specifically engineered for EGR systems, significantly enhancing cleaning capability to keep the engine internals as clean as new.

Specifically controls carbon deposits on the piston crown and in piston ring grooves, ensuring cylinder sealing and preventing gas leakage.

Effectively enhances lubrication and protection for the piston ring-cylinder liner and valve-camshaft interfaces, making it particularly suitable for high-power diesel engines.

Selected base oil with high temperature and oxidation resistance, significantly extending oil drain intervals.

Sustained Total Base Number (TBN) retention capability, providing long-term protection against acid corrosion caused by high-sulfur diesel combustion.
