The invention discloses a hydraulic oil combination special for a loading machine. The hydraulic oil combination special for the loading machine is composed of, by weight percentage, 1.1%-1.3% of hydraulic oil complexing agent, 0.6%-0.8% of pour point reducer, 0.01%-0.025% of anti-foaming agent, 0.01%-0.025% of demulsifier, and 97.85%-98.28% of base oil, wherein the hydraulic oil complexing agentis composed of, by weight percentage, 45%-50% of zinc dialkyl dithiophosphate, 0.5%-5% of fluorine-containing antioxidant antiwear agent, 10%-20% of dioctyl diphenylamine antioxygen, 1%-5% of sodium sebacate antirust agent, 2%-15% of dispersing agent, and 0-37% of mineral oil. The hydraulic oil combination special for the loading machine is high in antioxidant and antiwear performance, and being tested through a Denison T6H20C double-pump bench, achieves a service life longer than 3000 hours and is good in compatibility with gear oil.
