Mobil Oil Company was founded in 1870, and its headquarters is in Texas. Rockefeller, the founder, entered the oil industry as early as 65438+ 1960 to establish an oil refinery, and it took six years to build the largest oil refinery in the United States.
The base oil of synthetic oil is divided into five categories, the first two are petroleum refining, and the third is VHVI base oil, which is a patented technology of Shell's isomerization by high hydrocracking or paraffin catalytic hydrogenation. PAO (poly-α-olefin), whose chemical name is "poly-α-olefin", is made into poly-α-olefin, that is, the fourth base oil, by separating ethylene and ice washing with gas or natural gas, and then through complicated processes such as polymerization and catalysis.
Characteristics of engine oil
Mobil lubricants include Mobil vehicle lubricants and industrial lubricants. With its strong technical strength, Mobil has promoted the overall progress of the lubricant industry. Mobil has mastered the synthesis technology and patents of the fourth synthetic lubricant base oil, poly (α-olefin) (PAO). PAO synthetic lubricating oil represents the advanced level of lubricating oil.
The biggest wear and tear of the engine is cold start. PAO synthetic oil contains no paraffin and has good fluidity at low temperature. At the moment when the engine starts, the engine oil reaches the lubricating points everywhere, and a protective film is quickly formed on the surface of the engine parts. The viscosity index of mineral base oil is 85~ 100, that of the third synthetic oil is about 120, and that of PAO synthetic oil is above 140.
