What are the reasons for the high fuel consumption of the Toyota Yaris?

[Juan]

Here are the specific reasons for the high fuel consumption of the Toyota Yaris: Affected by temperature: Fuel consumption fluctuates due to temperature changes. In winter, the lower temperatures lead to increased fuel consumption. Long-term lack of maintenance: Dirty engine oil and air filters can also cause increased fuel consumption. Dirty engine oil leads to poor lubrication, increasing resistance in the engine's moving parts, which requires more energy to overcome, resulting in higher fuel consumption. Insufficient tire pressure: Insufficient tire pressure increases the contact area between the tires and the ground, leading to greater friction and driving resistance, which in turn raises fuel consumption. The normal fuel consumption for the Toyota Yaris is 6L per 100 km for the 1.3L automatic version and 7L per 100 km for the 1.6L automatic version.
