Abstract: The hydraulic equipment operating stably and safely for a long term was influenced directly and seriously by the performance of hydraulic oil. There were many kinds of index for evaluation performance of hydraulic oil, and the simple comparison of single index was general method to appraise and get the best product, which could not be comprehensive, objective and reasonable. In this paper, taking appli-cation hydraulic oil for injection molding machines for example, the analytic hierarchy process was used to comparing of the performance index of hydraulic oil comprehensively. And then based on the AHP, the weight coefficient of each performance index was determined, and the comprehensive evaluation model was established. The result of the consistency test of the model showed than it met the requirements with the higher credibility.
