How Many Kilometers Should a Heavy Truck Go Before Changing Engine Oil?

1 Answers
OChristian
07/30/25 7:46am
Heavy trucks generally require an engine oil change every 5,000 kilometers. Below is relevant information about automotive engine oil: 1. Importance: Engine oil is extremely crucial for the engine. Inside the engine, it not only serves as a lubricant but also performs functions such as cleaning, sealing, buffering, rust prevention, and heat dissipation. 2. Working Principle: When the engine is running, the oil forms a thin film on the surfaces of various components within the engine, preventing direct contact and friction between these parts. 3. Regular Replacement Needed: The performance of engine oil degrades over time with use, necessitating regular replacement. Prolonged intervals between oil changes can accelerate engine wear.

The country has relevant regulations regarding vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle does not include side mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. In other words, in the national standard, the significance of vehicle width data is to ensure enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, the national regulation stipulates that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of public roads.
