306 GTI FUEL

Hello, I am thinking of buying 306 gti right now, but when I get lpg, how much fuel will it burn? Can anyone help if they have knowledge? and if there is any other problem or something, I would be happy if I am given information about the problems.

You can solve the fuel issue with LPG, but you will find a clean 306 gti hard, my brother Heleki is not used in Istanbul.
