Long-distance treks and frequent loading/unloading in short- and medium-distance transportation present two distinct challenges. For vehicles, a “one-size-fits-all” maintenance approach is insufficient. Only by developing differentiated maintenance plans based on actual vehicle condition and mileage can your car maintain its powerful performance for a long time. Today, we’ll explain the maintenance of key components, from “energy replenishment” to “system purification.”

Power System
(1) Long-Distance Transportation
Continuous high-intensity operation puts a significant strain on the engine, increasing the risk of incomplete fuel combustion. Therefore, it is essential to use compliant, high-quality engine oil and consistently use a functional automotive urea solution. This effectively prevents urea crystallization from clogging the nozzles, avoiding “indigestion” in the power system and ensuring combustion efficiency.
(2) Short- and Medium-Distance Transportation
Frequent start-stop cycles place higher demands on the lubrication system. It is recommended to use engine oil with excellent low-temperature fluidity to significantly reduce cold-start wear. Meanwhile, functional diesel additives can be added regularly. These act like “cleaners,” effectively removing carbon deposits from the combustion chamber, improving diesel combustion efficiency, and making the vehicle start faster and more powerful.

Chassis Components
(1) Long-Distance Transportation
Like an “endurance marathon,” prolonged high-speed driving can easily lead to tire overheating. Installing a tire pressure monitoring system for real-time monitoring is crucial, and it is recommended to stop and check the wheel hub temperature every 4 hours of driving. Regular checks of brake pad wear and suspension bushing condition are also necessary to ensure a solid foundation for driving safety.
(2) Medium- and Short-Distance Transportation
Frequent loading and unloading pose a challenge to chassis resilience. Maintenance focuses on strengthening rust prevention and lubrication of key connection points such as frame welds and leaf springs (keeping “joints flexible”) to enhance the overall fatigue resistance of the chassis.

Vehicle Cabin
(1) Long-Distance Transportation
After each transportation mission, the vehicle urgently needs a thorough “rest and recharge.” Parking in a flat area allows the long-term stressed suspension system to fully relax. Strictly adhere to the maintenance mileage cycle for changing key fluids such as engine oil and gear oil, preventing “operation with defects” and avoiding vehicle “functional malfunctions.”
(2) Short- and Medium-Distance Transportation
Daily “rest maintenance” is essential. Clean the cab interior daily after parking to create a comfortable environment. Replace the air conditioning filter quarterly to ensure air circulation and prevent dust accumulation that could obstruct the air conditioning system’s breathing, affecting the health of passengers.
-
Aftertreatment System
The aftertreatment system acts as the vehicle’s “purification engine,” requiring regular maintenance to maintain its efficient “metabolic detoxification” capabilities.
(1) SCR System
Regardless of the transportation scenario, continuous use of high-quality functional automotive urea solution is fundamental. Inferior urea easily leads to crystallization and blockage in the nozzles and mixing chamber, causing fault codes and power limitations (torque and speed limits), ultimately resulting in soaring fuel consumption and increased maintenance costs.
(2) DPF Regeneration Management
Long-distance driving: Higher exhaust temperatures facilitate passive regeneration (automatically completed by the system), resulting in a relatively low risk of blockage and generally requiring no additional intervention.
Short to medium distance driving: Due to frequent start-stop or low-speed operation, exhaust temperature is often insufficient, leading to a high reliance on active regeneration. It is recommended to monitor DPF carbon load monthly and avoid prolonged low-load operation.
Using a functional DPF regeneration accelerator can significantly accelerate soot oxidation and rapidly reduce carbon load, thereby extending the regeneration cycle and reducing the number of regeneration cycles, achieving auxiliary fuel-saving and consumption-reducing effects.
Whether it’s a long journey or commuting between cities, mastering scientific maintenance is essential to keeping your car in good condition and driving smoothly on your road to success.
