it spend 20 liter for 80 km (4 km/liter = 2.5 mile / 0.264 gallon = 9.5 mpg .....!!!!!!!!!!!!!!!!)

where is the problem ...........
The posabilities are nearly endless, but I woudl start by changing plugs and wires as they are the most common culprits. Get NGK V Grove copper plugs, they run about $2 USD here in the states. Is the check engine light on? If so pulling the codes would give us much better insight into the problem.
