[ElijahFitz]

Passat this car consumes a large amount of fuel, the solution is to clean the engine regularly. The methods to address high fuel consumption in Passat are as follows: 1. Engine carbon deposits: Engine carbon deposits are one of the very important reasons, caused by using unsuitable engine oil. 2. Oxygen sensor: The oxygen sensor, as an internal control unit of the car, mainly monitors the air-fuel ratio of the engine. Once damaged, it will cause an imbalance in the engine's air-fuel ratio, leading to a sudden increase in fuel consumption. 3. Regular replacement of the three filters: During the use of the vehicle, it is necessary to regularly replace the oil filter, air filter, and fuel filter. If not replaced for a long time, they will become dirty, affect performance, and send wrong information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits.
