My car is consuming a lot of fuel

• Faulty Oxygen Sensors
• Dirty or Clogged Air Filter
• Dirty or Faulty Fuel Injectors
• Faulty Mass Air Flow Sensor
• Fuel System issues
• Worn Spark Plugs
• Exhaust System Problems
• Engine Overheating

Many things can cause high fuel consumption, it’s generally not a quick and easy diagnosis. Anything from low tire pressure or worn out tires to your air/fuel mixture running too rich (too much fuel) or lean (too much air). It can be caused by improper alignment, dirty sensors, exhaust or intake leaks, engine misfires, and improper brakes. Further, operating conditions can cause low MPG as well; frequently accelerating very quickly, riding the brake, incorrect fuel type for the application or it can be caused by your cars computer in certain (unlikely) situations. There are other things that can cause it as well but you get the idea. If you fill in a little more info about when this started happening, the circumstances concerning your car at that time, environmental factors and any other pertinent data you can think of, I will try to help you narrow it down a bit
