What does the SJ oil grade mean?
1 Answers
Oil grade SJ refers to mineral oil. Below is the classification method for oil grades: 1. AB series: Gasoline and light-duty diesel engine oils. 2. C series: Catalyst-compatible engine oils. 3. E series: Heavy-duty diesel engine oils. Here is extended information about the functions of automotive engine oil: 1. Reduces wear: Separates the surfaces of relatively sliding components to minimize wear. 2. Cools the engine: Carries heat back to the oil pan and dissipates it into the air, assisting the radiator in cooling the engine. 3. Flushes contaminants: Circulates carbon deposits, sludge, and wear particles from engine components back to the oil pan, using the flow of lubricating oil to flush away dirt generated on the working surfaces of the parts.
