The fuel tank of my 2004 model Peugeot automatic gasoline 1.4 vehicle is 40 liters. I do the full tank for 360 TL, I drive 250 km. This is urban consumption. Gasoline is 9 TL. It burns 1.25 TL. I don't think it's normal at all. The spark plugs were changed, the exhaust was changed, the engine oil was changed, the solenoid valve was changed, but the fuel did not drop again.. Any suggestions?
