What are the reasons for the high fuel consumption of the Passat B5?

[Lorraine]

Passat B5 has high fuel consumption for the following reasons: Low fuel quality: When the fuel quality added to the car is too low, the fuel and mixed gas cannot fully burn in the engine, resulting in partial fuel waste and increased fuel consumption. Adding high-quality fuel can reduce fuel consumption to a certain extent. Aggressive driving: When the driver drives too aggressively, the engine speed tends to be relatively high, which can easily cause the car engine to operate under overload, leading to high fuel consumption. It is necessary to change driving habits, drive gently, learn to brake in advance, and start slowly. Severe engine carbon deposits: When engine carbon deposits are too severe, fuel cannot be transported normally, and the car will experience increased fuel consumption and weakened power. It is necessary to clean the engine carbon deposits in time. Excessive vehicle weight: When the car's weight is too high, it increases the burden on the engine, leading to high fuel consumption. It is necessary to reduce the car's weight.
