Fuel consumption

Guys, I just registered in the forum, so I may be wrong. I am sorry already. 15 days ago I bought 2006 model gasoline + 307 sw with LPG 1.6 1.6 on the road computer, writes 9.4 in fuel consumption. I don't know if you enlighten me on this subject

When the tube is fitted with a gasoline vehicle, the vehicle burns 20% more than the amount of fuel it consumes while operating at LPG. Your savings save the difference between the liter price of gasoline and gas.
I'm not sure, but I think it's the fuel consumption that appears on the road computer.

first of all welcome furkan wishing you to use your vehicle without accident or honey. instant fuel consumption you see. if you set it to 100 km average fuel consumption on the trip computer, it's ok
