There are a number of causes of excessvie fuel consumption but I doubt your car would run with the fuel to air ratio required to consume 24 litres in a 100km. Your consumption is not excessive so much as abnormal. Therefore, are you sure your consumption callculations are correct? Has someone been siphoning your fuel tank? Do you have a fuel leak? The stuff stinkls so you should easily determine a fuel leak by sniffing around the engine bay, the fuel tank area and looking under the car for driips or puddles.
Even if your calculations are incorrect, you are still obviously concerend that your car is using way too much fuel. Excessive fuel consumption can be attributed to a number of causes including but not limited to, incorrect timing, clogged air filter, bad spark plugs, bad sensor or other faulty component in the emmision control system, dragging brakes, under inflated tires, bad driving habits, towing heavy or flat fronted trailers, very hilly driving, poor aerodynamic conditions eg, driving with items on roof rack, or with all windows open. More than one of these conditions may exist at the same time which will increase fuel consumption still further.
You probably need to give more information about the way you use the vehicle. Is the vehicle heavily laden with passengers and baggage most of the time or do you tow trailers regularly. Perhaps you do both at the same time? Do you have any pre-existing problems with the vehicle that you know about. For example, do you have a check engine light illuminating on the dash?
