Clean engine carbon deposits, check the oxygen sensor, and regularly replace the three filters. Here is more information about fuel consumption: 1. Causes: Tire pressure: If it is too low, it should be replenished in time; Tire wear: When the wear is severe, signs of slipping will often appear, which will also increase fuel consumption; Engine carbon deposits: It is recommended to add a certain amount of cleaner when refueling; Oxygen sensor: Once damaged, it will cause an imbalance in the air-fuel ratio of the engine, and fuel consumption will suddenly increase; Failure of a certain engine control unit: Replace it as soon as possible. 2. Brief description: Fuel consumption refers to the amount of fuel consumed by a vehicle traveling 100 kilometers on the road at a certain speed.

I remember once driving an old Corolla when the fuel consumption suddenly skyrocketed, and I realized that low tire pressure really makes the wheels feel like they're dragging a heavy load. Later, I found that regularly checking tire wear and maintaining the air filter on time is crucial—those dust-clogged filter inlets force the engine to consume extra fuel. It's counterintuitive, but driving with windows down on the highway actually burns more fuel than using AC, as wind resistance tests show a 15% increase in consumption above 80km/h. After cleaning carbon deposits with fuel additives, my mileage returned to the normal 7L per 100km. Sharing these tips with fellow drivers helped many beginners—they said it worked wonders.
