Embodiment 1

[0029] It is prepared by blending the following components in mass percentage:

[0030]

[0031] The preparation steps are: according to the mass percentage ratio, put the composite base oil into the blending kettle, and put the composite anti-oxidant and anti-corrosion agent, the composite metal detergent, and the composite ashless dispersant in sequence under the airtight stirring at 60°C , metal deactivator, antirust agent, antifoam agent, viscosity index improver, stir evenly until completely dissolved, and let stand for 3 hours. Just after filtering.

Embodiment 2

[0033] Blend the following components in mass percentage:

[0034]

[0035] The preparation steps are: according to the mass percentage ratio, put the composite base oil into the blending kettle, and put in the composite anti-oxidant and anti-corrosion agent, the composite metal detergent, and the composite ashless dispersant in sequence under the airtight stirring at 80°C , metal deactivator, antirust agent, antifoaming agent, viscosity index improver, stir evenly until completely dissolved, then let stand for 2 hours. Just after filtering.

Embodiment 3

[0037] Blend the following percentages by weight:

[0038]

[0039]

[0040] The sum of the above components is 100%.

[0041] Preparation steps are the same as in Example 1.

[0042] Measure through technical supervision department, the physical and chemical index of the oil product of the embodiment of the present invention 1 is:

Abstract

The invention discloses environment-friendly and energy-saving gasoline engine lubricating oil, which is composed of composite base oil, a composite oxidation and a corrosion inhibitor, a composite metal detergent, a composite ashless dispersant, a metal passivator, an antirusting agent, an antifoaming agent and a viscosity index improver, wherein the base oil is compounded from poly-alpha-olefin (PAO) and dioctyl sebacate. With the adoption of the gasoline engine lubricating oil, energy conservation, long oil change period, and reduction for waste oil, waste gas and particulate matters are realized, biodegradability is high compared with the traditional lubricating oil, the fuel economy of an engine is improved, the service life of the engine is prolonged, and the generation of oil sludge and carbon deposition in the engine can be inhibited; and the base oil technical requirements of quality grade specifications SG, SH, SJ, SL, SM and SN of gasoline engine lubricating oil, and the performance requirements of multi-grade oil with viscosity grades 0W, 5W, 10W, 15W, 20W and the like can be met.

Description

technical field [0001] The invention belongs to the field of environment-friendly and energy-saving gasoline engine lubricating oil. Background technique [0002] my country's automobile industry started in the 1950s, and today China has become a major automobile production and consumption country. In the case of soaring global energy prices and negative growth in car sales in developed countries, my country's car sales still maintain strong growth, and with the growth of GDP and the decline of car sales prices, my country's auto industry will still maintain stable growth in the next few years According to forecasts, my country's car ownership will reach 130 million in 2020, and it is expected to become the world's largest car market. [0003] In the automotive industry, tribological behavior is a major cause of mechanical failure and energy consumption in vehicles. According to the typical vehicle energy distribution measured by the US Environmental Protection Agency (EPA)...
