How many k's to a full gas tank

[locodave]

Hi Guys,

Thinkin of converting my vx to gas. Just wondering how many k's you get out of a full gas tank? And roughly how much is it to fil it up.

I did a search but couldnt find it! But i did read on some of the consequences!!

Thanks

im not sure what sort of milage my father gets in his VSIII when running lpg but he wouldn't go back even though he only has a smallish tank that was put where the spare wheel used to go
