Low-sulfur gasoline and diesel lubricating oil

Abstract

The invention provides low-sulfur gasoline and diesel lubricating oil. The low-sulfur gasoline and diesel lubricating oil is prepared from 60-70 parts of base oil, 20-30 parts of phosphorus-containing anti-wear agent, 6-10 parts of anti-corrosion agent and 5-8 parts of detergent. According to the low-sulfur gasoline and diesel lubricating oil, by means of new components of multi-component lubricating oil, not only is the sulfur content of the lubricating oil controlled, but also stronger anti-wear property of the lubricating oil is achieved, and therefore the lubricating problem caused by low-sulfur gasoline and diesel is solved.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a low-sulfur gasoline and diesel lubricating oil. Background technique [0002] As environmental protection puts higher and higher requirements on the quality of gasoline and diesel, the sulfur content in gasoline and diesel is strictly controlled, and the lubricity problem of gasoline and diesel is gradually exposed. The experiment of gasoline and diesel lubricity evaluation shows that most low-sulfur gasoline and diesel The lubricity is very poor, and diesel fuel with a sulfur content of less than 500mg / g may cause engine wear. If according to National V, the sulfur content of gasoline and diesel is less than 50mg / g, and the World Fuel Standard IV even requires the sulfur content of gasoline and diesel to be 10ug / g, the low sulfur content of gasoline and diesel will become the development trend of gasoline and diesel, but the ensuing It is the lubrication problem of ul...
