Why does the Mazda 6 have high fuel consumption?

[LeilaniDella]

Mazda 6 has high fuel consumption for the following reasons: 1. The quality of the fuel added is too low: When the fuel quality added to the car is too low, the fuel and mixed gas cannot fully burn in the engine, resulting in some fuel waste, which leads to an increase in the car's fuel consumption. 2. The driver drives too aggressively: When the driver drives too aggressively, the engine speed tends to be relatively high, making it easy for the car engine to overload, thus increasing fuel consumption. 3. Severe engine carbon buildup: When the engine carbon buildup is too severe, the fuel cannot be transported normally, so the car will show symptoms of increased fuel consumption and weakened power. 4. The car's self-weight is too large: When the car's self-weight is too large, it increases the burden on the engine, leading to higher fuel consumption.
