What type of engine oil does the BJ40 use?
1 Answers
The BJ40 series is equipped with turbocharged engines, so it is recommended to use fully synthetic engine oil with a viscosity of 40. Turbocharged engines have higher requirements for engine oil. More details are as follows: 1. Engine oil is known as the lifeblood of the engine. Inside the engine, it not only lubricates but also cleans, seals, buffers, dissipates heat, and prevents rust. Without engine oil, the engine cannot operate normally. During operation, the oil forms a thin film on the surfaces of various engine components, preventing direct contact and friction between them. 2. When selecting engine oil viscosity, it is essential to choose the appropriate viscosity based on your engine's technical characteristics. The viscosity of the oil should neither be too high nor too low. If the viscosity is too low, the oil cannot form a stable film inside the engine. If the viscosity is too high, it will increase the resistance during engine operation, affecting power output and fuel economy. Generally, a viscosity of 40 is suitable for turbocharged engines. 3. Over time, the performance of engine oil degrades, so it needs to be replaced regularly. It is advisable to change the oil on schedule during regular vehicle use and replace the oil filter with every oil change. When purchasing an oil filter, always opt for genuine products from reputable brands.
