Free 4WD to good home !!!

Hi All, How would you like a Free 4x4 no strings attached ??????, now I have your attention, I thought of "Free Sex" as a topic but thought this would get more hits ??? I new I wouldn't get your attention if I asked about Fuel figures for a 80 series LC on petrol/gas !!!!!!!!!! My brother inlaw is new to 4x4'n and has just bought a 80 series LC on petrol/gas, next week we are planning a trip to the high country, (Before rain/snow sets in ??) nothing too serious to start off with. As I have only ever owned Diesels and have now idea about the fuel consumption of petrol/gas LC, I was wondering if someone could give me an idea how many KLM's we could expect to get 4x4'n on petrol / gas, has standard fuel tank 95ltr and gas tank mounted in spare wheel well underbody not sure on capacity but I would imagine it would be a standard set up.
Your fuel figures will assist in planning where we can go. As I have long range tanks in my truck I tend to forget about distances on shorter trips.As stated I wouldn't know what sort of fuel figures petrol/gas return would hate to take him on his first trip and run out of fuel ???
All suggestions greatly appreciated
