Abstract

The invention relates to engine oil suitable for multiple fuels, and belongs to the field of engine oil for an automobile. The engine oil comprises the following raw materials in mass portion: 33 to 36 portions of base oil 150SN, 22 to 24 portions of base oil VHVI H350 (type III), 15 to 17 portions of poly alpha-alkene, 2 to 4 portions of ester oil of C8 to C10, 11 to 13 portions of ethylene-propylene copolymer the molecular weight of which is between 63,000 and 108,000 as viscosity index improver, 0.4 to 1.2 portions of zinc dialkyl dithiophosphate as additive for resisting oxidation and corrosion as well as abrasion, 1.1 to 4.8 portions of alkyl phenol calcium and 1.9 to 2.5 portions of calcium sulfonate as detergent, 3.8 to 5.0 portions of polyisobutene succimide as dispersant, and 0.001 to 0.003 portion of methyl silicone oil as antifoaming agent. The engine oil meets performance requirements of automobile and engine manufacturers at home and abroad on gasoline engine oil and sedan diesel engine oil.

Description

technical field [0001] The invention belongs to the field of engine oil for automobiles. Background technique [0002] As we all know, automobile engine oil is mainly divided into two categories, namely gasoline engine oil and diesel engine oil. Automotive engine oil suitable for gasoline fuel is called gasoline engine oil, and automotive engine oil suitable for diesel fuel is called diesel engine oil. Due to the different engine fuels, gasoline and diesel engine oils have certain differences in performance, mainly in terms of low-temperature deposition resistance and high-temperature detergency. [0003] Engine oil is the liquid part of the engine, which plays the roles of lubrication, cooling, sealing, vibration damping, anti-corrosion and anti-rust in the engine. The quality of engine oil affects engine performance, emissions and reliability. With the improvement of automobile technology, the requirements for the performance of engine oil are also getting higher and hi...
