What Cars Are Suitable for 5W30 Engine Oil?
1 Answers
5W30 engine oil is suitable for Japanese and Korean cars. The 'W' stands for winter, and the number before 'W' is 5. The smaller this number, the better the oil's fluidity at low temperatures, indicating a lower applicable minimum temperature. The number after 'W' is 30, referring to the oil's viscosity at 100 degrees Celsius. The higher this number, the higher the oil's viscosity, the stronger its resistance to high temperatures, and the better its high-temperature protection performance. Engine oil is a substance enhanced with additives in base oil, mainly containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers.
