▎ 摘　　要

NOVELTY - Good viscosity performance fully synthetic gasoline engine oil comprises 25-30 pts. wt. gas to liquids base oil, 35-45 pts. wt. poly alpha-olefin, 5-8 pts. wt. adipate diester, 9-15 pts. wt. gasoline engine oil complexing agent, 5-9 pts. wt. viscosity index improver, 5-7 pts. wt. polyester, 1-2 pts. wt. high performance reinforcing agent and 0.3-0.8 pts. wt. pour point depressant. USE - Used as good viscosity performance fully synthetic gasoline engine oil. ADVANTAGE - The fully synthetic gasoline engine oil: has excellent viscosity-temperature performance and shear stability, excellent oxidation stability, hydrolysis stability and low temperature fluidity and adsorption capacity, high-temperature cleansing and dispersibility, thermal stability and conductivity and heat dissipation performance; forms a frictional adsorption oil film which can reduce the friction coefficient and wear of the friction surface of the engine; improves the load-bearing and anti-wear performance of engine oil; and reduces the formation of deposits in engine oil at high and low temperatures. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing good viscosity performance fully synthetic gasoline engine oil, comprising (i) adding gas to liquids base oil, poly-alpha-olefin and adipate diester into the reaction kettle, stirring and heating to 55-65℃; and (ii) adding in the viscosity index improver, high-performance reinforcing agent, polyester, gasoline engine oil compounding agent and pour point depressant and stirring at 55-65℃ for 3 hours until the mixture is evenly mixed to obtain a fully synthetic gasoline engine oil.
