Is the fuel consumption of A6L 2.8 high?

[LaRebecca]

A6L 2.8's fuel consumption is not too high. The reasons for high car fuel consumption include: Excessive carbon buildup in the vehicle: Carbon deposits in the throttle body, fuel injectors, intake manifold, or piston top can lead to incomplete combustion, thereby increasing fuel consumption. Faulty car sensors: This is also a major cause of increased car fuel consumption. Long time without oil change: Prolonged use of engine oil and oil filters reduces their ability to clean impurities, leading to excessive impurities in the oil. Relevant information about fuel consumption is as follows: Constant-speed fuel consumption: This refers to the fuel economy indicator when the car is driving at a constant speed on a good road. Road cycle fuel consumption: This is the fuel economy indicator measured when the car is driven in repeated cycles according to specified speeds and time norms on the road, also known as multi-condition road cycle fuel consumption.
