Problems solved by technology

[0005] However, the existing public ACEA-2010 version A5 / B5 products cannot meet the performance requirements of this test, and have the disadvantage of being worse than the reference oil in the comparison process with the reference oil
[0006] The prior art discloses technical schemes using molybdenum-containing compounds as friction reducers, such as binary molybdenum and organic friction reducers. Friction reducer does not significantly change the energy-saving effect, and still cannot solve the above technical problems

Abstract

The invention discloses energy-saving light-load engine oil. The energy-saving light-load engine oil is prepared from the following ingredients in percentage by weight: 99.4-99.7% of lubricating oil and 0.3-0.6% of phosphorus-free molybdenum salt anti-friction agent. According to the energy-saving light-load engine oil, the phosphorus-free molybdenum salt anti-friction agent and the A5 / B5 lubricating oil are blended, and the technical problem that products cannot meet energy-saving technical requirements of an OEM is technically solved through adding a small amount of reinforcing agent into the existing lubricating oil. The added energy-saving reinforcing agent does not violate the technical principle of small formula change and does not affect the technical features of the original formula; the added reinforcing agent is moderate in viscosity and good in solubility and can be directly blended, thereby having high operability; the amount of the added reinforcing agent is small, so that the influence on the overall cost of the product is not high; proven by simulated tests and bench tests, the effect of used technologies is obvious; and the scope of technical application is wide, and the energy-saving light-load engine oil can be popularized and applied to other light-load engine oil products with requirements on energy-saving performance.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a light-load engine lubricating oil with reinforcing and energy-saving properties. Background technique [0002] A domestic car production and operation company requires its engine loading oil and service oil not only to meet the ACEA-2010 version A5 / B5 specification requirements, but also to meet its specific energy-saving performance and strict technical requirements. The engine must pass the requirements in Table 1. Bench evaluation test. [0003] Table 1 Engine Energy Saving Bench Requirements [0004] [0005] However, the existing public ACEA-2010 version A5 / B5 product cannot meet this test performance requirement, and has the disadvantage of being worse than the reference oil in the comparison process with the reference oil. [0006] The prior art discloses technical schemes using molybdenum-containing compounds as friction reducers, such as binary molybdenum and organic friction ...
