The present invention relates to an engine lubricant composite for methanol gasoline, which is prepared with 1.0 percent to 5.0 percent of metal detergent, 2.0 percent to 6.0 percent of ashless dispersant, 1.0 percent to 2.0 percent of oxidation and corrosion inhibitor, 0.1 percent to 1.0 percent of auxiliary antioxidant, 0.05 percent to 1.0 percent of glycol ester, 0.0005 percent to 0.001 percent of methyl-silicone oil, 45 percent to 80 percent of base oil and 15 percent to 40 percent of remnant oil. A comparison test, a comparative road test and a comparative engine pedestal test are conducted for the lubricant and the 15W/40SG gasoline engine lubricant, and the results show that the performance of the lubricant is better than the performance of the 15W/40SG gasoline engine lubricant, having the advantages of oxidation resistance, nitrification resistance, good alkali-conserving property, etc., and can reduce the carbon deposition of an engine. An engine pedestal test shows the following results: the external characteristic power is increased, and the effective fuel consumption rate is reduced by 2.3 percent on average; in terms of load characteristic, the effective fuel consumption rate is reduced by 2.7 percent on average; under the working conditions of both high idle speed and idle speed, CO is not detected, and the emission of HC is equal.
