How is Defu Jinba Engine Oil?
1 Answers
Defu Jinba engine oil is quite good. Synthetic products are developed through carefully controlled chemical reactions involving pressure, temperature, and the proportion of constituent elements. This process yields pure compounds that enhance lubrication properties, thereby promoting energy efficiency, improving equipment protection, enhancing equipment reliability, and extending the oil's service life. Therefore, the oil used should possess the anti-sintering performance of gear oil, the low-temperature fluidity of hydraulic oil, the detergency and dispersancy of engine oil, as well as excellent oxidation stability, anti-foaming properties, rust prevention, and rubber compatibility for sealing. 1. High-temperature grades for summer use include 20, 30, 40, and 50. The larger the number, the higher the viscosity, and the higher the maximum applicable temperature. 2. Low-temperature grades for winter use include 0W, 5W, 10W, 15W, 20W, and 25W. The letter 'W' stands for Winter, and the smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the minimum applicable temperature.
