◆In accordance with German API CF-4 and European ACEA B3-98 quality grade standards,imported hydrogenated base oil is used to minimize wear and effectively extend the service life of the engine. ◆The superior high temperature cleaning property prevents piston ring adhesion and cylinder sleeve polishing due to direct fuel injection technology and maintains high engine cleanliness. ◆The oxidation stability and thermal stability of turpentine are excellent,and the viscosity increase and the formation of piston sediments are controlled effectively. ◆The innovative and rational formulation system for energy conservation and friction reduction effectively reduces the consumption of industrial fuel and engine oil and prolongs the oil changing cycle.
