What are the reasons for the sudden increase in fuel consumption of the Corolla Hybrid?

[StMichael]

The reasons for the increased fuel consumption of the Corolla Hybrid include: 1. Tire pressure: Insufficient tire pressure and tire wear. Low or insufficient tire pressure increases friction between the tires and the ground, leading to greater resistance and higher fuel consumption. Severe tire wear can cause frequent slipping, which also increases fuel consumption. 2. Carbon deposits: Pay attention to fuel quality and clean carbon deposits regularly. Poor-quality gasoline can lead to more carbon deposits. Excessive carbon deposits roughen the intake pipe walls, affecting air intake efficiency and mixture quality, causing a sharp rise in fuel consumption. Therefore, fuel quality cannot be ignored, and cleaning carbon deposits every six months is essential. 3. Driving habits: Everyone has different driving habits. Poor driving habits can also lead to higher fuel consumption, so good driving habits are a crucial factor in preventing increased fuel consumption.
