I have been driving this chic car since November 2002.However, I don’t get under 8litres of fuel consumption at 100 kilometres, no matter how I drive.Indicated is it in the list with 6.8 litres of super.The dealer says he can’t change it,as long as the exhaust gas values are correct-they’re ok.What could it be????????Maybe someone like the average values of consumption are determined-especially at what speed?
