Hybrid automobile engine lubricating oil composition and preparation method thereof

The invention provides a hybrid automobile engine lubricating oil composition and a preparation method thereof. The hybrid automobile engine lubricating oil composition comprises the following components: (A) an organic sulfur-phosphorus compound; (B) alkylated diphenylamine; (C) a polyisobutylene succinimide ashless dispersant and/or a boronized polyisobutylene succinimide dispersant; (D) a detergent; (E) zinc dialkyl dithiophosphate; (F) a composite friction modifier; (G) a metal corrosion inhibitor; (H) a major amount of a lubricating base oil; wherein the structure of the organic sulfur-phosphorus compound is shown as a formula (I): # imgabs0 #, and the definition of each group is shown in the specification. The hybrid vehicle engine lubricating oil composition has excellent high-temperature cleaning performance, oxidation resistance and wear resistance, and can meet specification requirements of SP/GF-6, ACEA C6 and GLV-1 and harsh requirements of hybrid vehicle engine lubricating oil. 本发明提出了一种混动汽车发动机润滑油
