What are the solutions for high fuel consumption in Peugeot 307?

[DanteMarie]

Here are the solutions for high fuel consumption in Peugeot 307: 1. Engine carbon deposits: Excessive carbon deposits can lead to incomplete combustion of the air-fuel mixture, increasing fuel consumption. Therefore, it is necessary to regularly clean engine carbon deposits, including those in the intake tract, throttle valve, fuel injectors, and cylinder. The solution is to clean the carbon deposits in a timely manner. 2. Vehicle weight: Carrying excessively heavy items in the vehicle can increase fuel consumption by about 2% compared to normal driving. The solution is to avoid carrying too much cargo and reduce the vehicle's weight. 3. Air filter: A clogged air filter can obstruct air intake, resulting in an overly rich air-fuel mixture or a blocked exhaust pipe. The solution is to replace the air filter promptly. 4. Spark plugs: Aging spark plugs with excessively worn electrode gaps can cause insufficient ignition, leading to incomplete combustion of the air-fuel mixture and increased fuel consumption. The solution is to replace the spark plugs in a timely manner.
