The invention discloses
lubricant oil which is composed of, by weight, 100-150 parts of basic oil, 10-20 parts of an anti-wear agent, 5-10 parts of an anti-wear
enhancer, and 3-10 parts of an anti-
rust agent. Compared with the prior art, the
lubricant oil has the following advantages: 1) a mixture composed of
ferrocene, 3-(2-
thiophene)propionic acid and ethyl 2-chloro-6-fluorophenylacetate, in special ratio, is employed as the anti-wear
enhancer, so that the performance of anti-wear agents in the prior art is greatly improved, and the
lubricant oil is excellent in anti-abrasion performance; 2)by means of the basic oil in
specific weight ratio, namely, a mixture comprising
mineral oil of which the ISO-VG
viscosity grade is 100,
castor oil and poly-alpha-olefin PAO15 according to
mass ratioof 10:2:1, the lubricant oil is high in
fuel oil saving rate; and 3) the anti-
rust agent is a mixture of
petroleum sodium sulfonate,
triethanolamine borate and
amide according to the
mass ratio of 5:3:1, so that the lubricant oil has excellent anti-
rust performance.
