What are the reasons for a sudden severe increase in car fuel consumption?
2 Answers
Vehicle suddenly consuming excessive fuel is due to prolonged warm-up time. Below are relevant explanations regarding car fuel consumption: 1. Reasons: Persistently idling until the engine speed drops to normal or the water temperature rises to normal is essentially throwing money away. If the car's travel distance is too short each time, the engine's computer will instruct the fuel injector to spray more fuel when the water temperature is too low, ultimately leading to higher fuel consumption. Increased driving pressure also results in higher car fuel consumption. 2. Solution: You can shift into gear and start driving after about half a minute of starting the vehicle, then drive in 1st gear for a short distance before proceeding normally.
My car's fuel consumption has suddenly spiked recently, which has me quite worried. Thinking about possible factors, insufficient tire pressure increases rolling resistance, making the engine work harder; worn-out spark plugs can't ignite properly, leading to incomplete fuel combustion and waste; a clogged air filter reduces airflow and increases fuel consumption; and blasting the AC, especially in summer, makes the compressor guzzle more fuel. Also, a faulty oxygen sensor can mess with the engine computer's control, causing an imbalance in the air-fuel mixture. I remember last year when I kept flooring the accelerator for quick acceleration, fuel consumption also skyrocketed. In short, if you notice this issue, don't delay—get a full checkup at the repair shop ASAP. Otherwise, it's both a safety hazard and a waste of money.
