What Causes Fluctuations in Average Fuel Consumption?

1 Answers
SanJanelle
07/30/25 10:23am
Average fuel consumption fluctuates for the following reasons: Vehicle age: Newer cars generally have lower fuel consumption. As a vehicle ages, especially after 5-10 years of use, its fuel consumption gradually increases. Maintenance condition: Carbon buildup in the engine can lead to incomplete combustion. Proper engine maintenance and carbon deposit removal can prevent fuel consumption fluctuations caused by poor or insufficient maintenance. Road conditions: Fuel consumption is also affected by driving conditions. Rough roads or frequent traffic congestion typically result in higher fuel consumption.
