Why is the fuel consumption of Trumpchi GS4 increasing?

[GrahamFitz]

Here are the reasons why the fuel consumption of Trumpchi GS4 is increasing: 1. Tire Pressure: Tire pressure does affect the vehicle's fuel consumption. Lower tire pressure causes the tires to flatten, increasing rolling resistance, which in turn leads to higher fuel consumption. 2. Dirty Engine Oil and Transmission Fluid: Engine oil and transmission fluid play a lubricating role in the engine and transmission, respectively. Over time, they inevitably become dirty. Dirty oil and transmission fluid reduce lubrication, causing the engine and transmission to consume more energy during operation, thus increasing fuel consumption. 3. Carbon Deposits: Carbon deposits can be considered the 'root of all evil,' as many engine faults are caused by them. Carbon deposits in the engine lead to a decrease in engine power, which correspondingly increases fuel consumption. Additionally, phenomena such as shaking, noise, detonation, and knocking are all related to carbon deposits.
