The invention discloses a lubrication wear reducing additive for aviation biofuel. The lubrication wear reducing additive comprises a lubricant, a wear reducing agent and an organic solvent. A mass ratio of the lubricant to the wear reducing agent is 1-5: 1. A mass ratio of the organic solvent to a mixture of the lubricant and the wear reducing agent is 0-0.5: 1. The lubricant is a carboxylate or an amide compound. The wear reducing agent is a borate, a phosphate or an organic molybdenum compound. The lubrication wear reducing additive solves the problem that aviation biofuel has poor lubricity in use so that engine oil pump and related flow control element wear is caused easily.
