What are the reasons for the excessive fuel consumption of Wuling Hongguang?

Here are the specific reasons for the excessive fuel consumption of Wuling Hongguang: 1. Affected by temperature: causing fluctuations in fuel consumption. In winter, the low temperature leads to increased fuel consumption. 2. The vehicle has not been maintained for a long time: dirty engine oil and air filters can also lead to increased fuel consumption. Dirty engine oil causes poor lubrication, increasing the resistance of various moving parts of the engine, requiring more energy to overcome the resistance, thus increasing fuel consumption. 3. Excessive carbon deposits in the vehicle: carbon deposits can accumulate in the throttle, fuel injectors, intake ducts, and piston tops. Excessive carbon deposits in any of these areas can lead to incomplete combustion, resulting in increased fuel consumption.
Last time I drove my Wuling Hongguang for delivery on the highway, I noticed the fuel gauge dropped unusually fast. The main issues stem from two aspects: First, the engine system—for example, a clogged air filter restricts airflow, causing the ECU to compensate by injecting more fuel; worn spark plugs with weak ignition lead to incomplete combustion, wasting fuel. A faulty oxygen sensor can also make the engine inject fuel blindly. Second, driving habits—frequent hard acceleration, sudden braking, or crawling in city traffic can increase fuel consumption by 20-30%. A fully loaded trunk, roof racks increasing drag, or underinflated tires (like dragging the tires) all contribute to fuel waste. I recommend first replacing the air filter, checking the ECU for trouble codes, and maintaining a steady speed while driving to save fuel.
