Abstract

The invention discloses environmentally-friendly energy-saving gasoline engine oil. The environmentally-friendly energy-saving gasoline engine oil consists of poly alpha olefin, three-time-hydrogenation low-coagulation base oil, a viscosity index improver, a clearing agent, a non-ash dispersion agent, an oxidation and corrosion inhibitor and organic molybdenum. The invention also provides a preparation method of the environmentally-friendly energy-saving gasoline engine oil. The method comprises the following steps: weighing poly alpha olefin, three-time-hydrogenation low-coagulation base oil,the viscosity index improver, the clearing agent, the non-ash dispersion agent, the oxidation and corrosion inhibitor and organic molybdenum in percentages by weight; then adding poly alpha olefin ina reaction still, warming to 65 to 75 DEG C, adding three-time-hydrogenation low-coagulation base oil and the viscosity index improver in a stirring state, after stirring, and after adding the clearing agent, the non-ash dispersion agent, the oxidation and corrosion inhibitor and organic molybdenum in sequence, and then stirring to obtain the environmentally-friendly energy-saving gasoline engineoil. The environmentally-friendly energy-saving gasoline engine oil is high oxidation stability, long in service life, low in pour point and wide in operating temperature; and due to the organic molybdenum is contained in the environmentally-friendly energy-saving gasoline engine oil, so that the friction and friction heat are reduced, the consumption of fuel oil is saved, and the abrasion of anengine can be reduced.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to gasoline engine oil, in particular to an environment-friendly energy-saving gasoline engine oil and a preparation method thereof. Background technique [0002] Gasoline engine oil refers to a type of automotive lubricating oil used in automobile engines to lubricate, reduce friction, clean, cool, seal, and prevent rust and corrosion. Gasoline engines are generally used as the power of cars and light vehicles. Their operating conditions range from on-off city driving to high-speed driving on expressways between cities. Therefore, the engine oil should have good high-temperature oxidation stability and anti-wear properties. In addition, it should have excellent ability to inhibit and disperse low-temperature sludge; in addition, due to the wide working range of gasoline engine oil, the temperature in cold regions can reach -40°C or even lower. If the viscosity is too large at low t...
