Introduction: On September 6, 1866, American John Ellis founded the Continuous-Oil-Refining company. While studying the possible therapeutic effects of crude oil, Dr. Ellis was disappointed to find no real medicinal value, but became very interested in its potential lubricating properties. He eventually abandoned medical practice and devoted himself to developing all-petroleum, high-viscosity lubricants for steam engines - using inefficient combinations of petroleum and animal and vegetable fats. He made a breakthrough in developing a petroleum that worked effectively at high temperatures, solving problems such as valve sticking, cylinder corrosion, and seal leakage. 2. Grade classification: Engine oil grades are divided into gasoline, diesel and gasoline-diesel universal types: Those beginning with the letter "S" represent gasoline engine oils, with specifications including: API, SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN; Those beginning with the letter "C" represent diesel engine oils, with specifications including: API CA, CB, CC, CD, CE, CF, CF-2, CF-4, CG-4, CH-4, CI-4. If both are present, such as SM/CF, it means the oil is a gasoline-diesel universal type.
