During long-distance transportation, vehicle maintenance is extremely important, especially for large trucks. Grease is an indispensable lubricant in many vehicle maintenance procedures. It is applied to wheel hub bearings to reduce the risk of wear.
The frequency of greasing is not fixed; it depends on the vehicle's load condition and driving environment. In addition to wheel hub bearings, other key parts of large trucks also require regular greasing to ensure smooth operation and extend service life. Therefore, arranging a reasonable maintenance cycle is crucial.
How many kilometers should a truck run before an oil change?
When maintaining a vehicle, the oil change interval should be adjusted according to the vehicle's specific conditions and the type of engine oil used. Generally speaking, mineral oil is recommended to be changed approximately every 5,000 kilometers; semi-synthetic oil every 7,500 kilometers; and fully synthetic oil can last up to 10,000 kilometers before replacement.
However, the oil change cycle is also affected by driving environments, personal driving habits and vehicle operating conditions. For example, frequent traffic congestion, sandy and dusty areas, or extreme temperatures may require an earlier oil change to ensure normal engine operation. Here is a brief introduction to the three types of engine oil:
Mineral Oil: Refined from crude oil, it is mainly composed of refined liquid hydrocarbons mixed with fuel oil, lubricating oil, cooling oil and other components. It undergoes a series of refining processes such as vacuum distillation and hydrotreating.
Semi-synthetic Oil: Based on Group III base oil, it is further purified through hydrocracking technology. It combines partial features of mineral oil and advantages of fully synthetic oil with a mixing ratio of 4:6.
Fully Synthetic Oil: A high-end grade of engine oil. It is made through complex chemical reactions using olefins extracted from gas and natural gas derived from crude oil. It delivers superior performance and a longer service life.
How often should a truck be greased?
Grease is essential in the maintenance of large trucks. Normally, regreasing is required approximately every 10,000 kilometers.
The actual interval varies according to the load weight and road conditions. Proper maintenance of wheel hub bearings is vital, as improper upkeep may lead to premature wear. Greasing is not a simple task and usually needs to be done by professional repair shops to ensure correct operation. Regular maintenance is critical to vehicle performance and service life. Neglecting maintenance may cause potential damage to the vehicle’s condition and normal operation.
The core function of grease lies in its lubricating properties. Due to structural design, grease cannot be easily injected into some spring pin parts, which is usually caused by the position of the oil outlet holes and contact with the bushing.
Lubricants protect components by blocking moisture, air, acidic substances and harmful gases. They also provide cushioning under impact loads and keep internal engine parts operating properly.
In summary, greasing is a key part of large truck maintenance. Regular and correct greasing helps keep the vehicle in good working condition.
