Abstract

The invention discloses energy-saving emission-reducing type gasoline engine oil and a preparation method thereof. The gasoline engine oil (API SN SAE 5W/40 specification requirements) is prepared from the following components in percentage by weight: 20-25% of 100N, 45-55% of 150N, 8-12% of PAO-4, 6.0-12.0% of a viscosity index improver SCR-261, 7-10% of a gasoline engine oil composite additive H9089, 0.001-0.01% of a defoaming agent T901, and 0.3-3% of a nano friction improver TND001. A nano functional material in the gasoline engine oil disclosed by the invention can be kept in a stable and uniform state for a long time without generating any layer chromatography and failure phenomenon. The product disclosed by the invention can be used for a gasoline engine of a high-class car, and the like, fuel oil can be reduced by 4-15%, pollutants can be reduced by 10-40%, power is increased by more than 6%, and cold-starting abrasion of the engine is avoided.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to gasoline engine oil for gasoline engines and a preparation method thereof. Background technique [0002] Studies have shown that 90% of car problems are caused by engine wear. It can be said that wear and tear is the root of all disasters. The research of General Motors Corporation of the United States shows that when the automobile engine stops for 4 hours, all the lubricating oil on the friction interface will return to the lubricating oil tank. At this time, when the engine is started, since the oil pump is too late to pump the lubricating oil to the lubricating parts, dry friction with periodic lubrication loss will occur in a short period of time, resulting in severe and abnormally strong wear of the engine. This kind of strong wear cannot be solved by lubricating oil at all. (Another relevant data study points out that this strong wear accounts for more than 70% ...
