Locomotive oil compound agent

MK-3425 Railway fourth generation locomotive oil compound agent

MK-3425 is a high-performance fourth-generation railway locomotive oil compound. It has excellent thermal oxidation stability and clean dispersion, which can effectively prevent the formation of deposits and maintain the high cleanliness of the engine for a long time. Excellent wear resistance and oil film protection extend the service life of the machine parts. The higher alkali value and excellent alkali value retention ability can effectively neutralize the combustion products of sulfur-containing fuels and prolong the oil change period.

Locomotive oil compound agent Dosage reference

The dosage in the oil is 14.7 %.
