I got a 2004 model 307 1.6 xt automatic vehicle with zavoli inline system lpg, it was about 1900 km lpg fitted. All maintenance of the vehicle has been done. According to my calculations, the city consumes 13.56 liters of lpg per 100 km. air conditioning & nbsp; closed. in quiet use and in places without heavy traffic. Is this consumption normal ... If not normal, what kind of turbine solution would you suggest?

according to the vehicle's factory settings. : It consumes 7,9 lt gasoline ...
