156 V6 2.5 Consumption too high?

Good evening, I got a V6 last week. Top car no rust, Tüv new, only 116.000 km . I’m full of enthusiasm, only a small shortage there is the consumption. I’m aware that no saving mobile is, hadr before n E46 316i and he has already been quite drunk for the small engine. So now the Alfa in the city country roads mix so 13 liters is that much? I don’t heize, ride nice and cozy. It’s about an automatic the Q-Sytem must say I’m never ready for automatic The car was also standing for about half a year. With kind regards
