How to Deal with High Fuel Consumption in Peugeot 307?

[SanBryce]

Peugeot 307 high fuel consumption solutions: 1. Engine carbon deposits: Excessive carbon buildup leads to incomplete combustion of the air-fuel mixture, increasing fuel consumption. Regular cleaning of engine carbon deposits is necessary, including intake tract, throttle valve, fuel injectors, and cylinder deposits. Solution: Clean carbon deposits promptly. 2. Vehicle weight: Carrying excessively heavy loads can increase fuel consumption by about 2% compared to normal driving. Solution: Reduce unnecessary cargo to lighten the vehicle weight. 3. Clogged air filter: Restricted airflow causes an overly rich mixture or blocked exhaust pipe. Solution: Replace the air filter in time. 4. Worn spark plugs: Excessive gap wear in spark plug electrodes results in insufficient ignition, causing incomplete combustion and higher fuel consumption. Solution: Replace spark plugs promptly. 5. Low cylinder pressure: Tests show that cylinder pressure below specified values increases fuel consumption by 20%-25%. Solution: Conduct timely cylinder pressure inspections.
