What are the reasons for the high fuel consumption of Dongfeng Tianlong 420?

[Brody]

Dongfeng Tianlong 420 has the following reasons for high fuel consumption: 1. Mechanical factors: Car malfunctions can lead to decreased efficiency, and the engine may be worn out or outdated. 2. Insufficient tire pressure: Regularly check the condition of the tires and maintain proper tire pressure, which not only saves fuel but also extends the lifespan of the tires. 3. Excessive warm-up time: After starting the engine, wait for about 30 seconds until all warning lights go off before driving. Rapid acceleration and sudden braking not only consume more fuel but also cause mechanical wear. Leaving the engine running with the air conditioning on for long periods while sleeping or waiting can lead to increased fuel consumption and engine carbon buildup. 4. Traffic factors: Short-distance usage. The engine does not reach its optimal operating temperature before reaching the destination, resulting in lower efficiency and unavoidable fuel consumption. This type of driving also makes the engine more prone to carbon buildup.
