preferably, the composition comprises the following components in percentage by weight: a base oil and an additive, the additive being added in an amount of 7.653% of the base oil, the base oil comprising at least three components: 69% of hydroisomerized base oil, 25% of alkyl naphthalene and 6% of poly-alpha-olefin, wherein the additive at least comprises ten components: 0.5 percent of octyl/butyl liquid diphenylamine, 0.3 percent of methacrylate pour point depressant, 0.5 percent of 2, 6-p-di-tert-butyl-p-cresol, 0.05 percent of benzotriazole fatty amine salt, 1 percent of molybdenum dialkyl dithiosulfate, 0.8 percent of tricresyl phosphate, 0.003 percent of composite anti-foaming agent, 0.3 percent of metal deactivator, 1.2 percent of fatty acid ester and 3 percent of sulfurized isobutylene;
preferably, the hydroisomerized base oil is 500N;
preferably, the alkyl naphthalene is AN 30;
preferably, the polyalphaolefin is PAO 600;
the method for preparing the special oil for the long-life clean vehicle gear comprises the following steps:
(1) adding the hydroisomerized base oil, alkyl naphthalene and poly-alpha-olefin into the reaction kettle, heating to 60-70 ℃, and stirring for 10-30 minutes;
