How to Reduce Increased Fuel Consumption?

[Herbert]

To address increased fuel consumption, you can clean engine carbon deposits and inspect the oxygen sensor. Here are more relevant details: 1. Regularly replace the three filters: During vehicle use, the oil filter, air filter, and fuel filter must be replaced periodically. If not replaced for a long time, they can become dirty and clogged, affecting performance and sending incorrect information to the engine control unit, leading to incomplete fuel combustion and increased engine carbon deposits. 2. Inspect the electronic control unit: Although the engine's electronic control unit is highly reliable, older vehicles may experience various issues, such as damaged integrated circuits, loose bolts, soldering joint failures, or malfunctioning resistors and capacitors. Problems with the engine control unit can directly cause difficulties in starting, increased fuel consumption, poor power performance, and thick black exhaust emissions.
