Abstract

The present invention provides a long-life gasoline engine oil composition, which contains a hydrogenated styrene-diene compound, zinc alkyldithiophosphate, monoalkyl molybdenum dithiocarbamate, polyol ester, a hindered phenol antioxidant, and a base oil. With this composition, vehicle fuel efficiency can be improved, oxidation stability can be increased, and the life span of engine oil can be extended.

Description

technical field [0001] The present invention relates to a long-life gasoline engine oil composition that can extend the interval between oil changes. Background technique [0002] Performance degradation due to oxidation, sludge formation due to friction and wear, and deterioration of the oil itself all affect the life of the oil. Since the oil is used under high pressure and low pressure for a long time, sludge formation due to oxidation, thermal decomposition, thermal polymerization, etc. will reduce the life of the oil. Therefore, use appropriate antioxidants to improve the oxidation stability of the oil. [0003] When friction and wear occur at high temperatures and in boundary lubrication, excessive heat is generated, increasing the viscosity and total acid value of the oil and the amount of generated sludge, thereby shortening the life of the oil. Therefore, despite the use of anti-wear additives to prevent friction and wear, when the oil is used under severe conditi...
