I agree Leg but I like the idea of Jester (it would make a nice game scenario). For fuel substitute you'll have several among the most simple types. The one which are readily available.

I don't know for Australia but in France, the only thing that prevent their wide use is state regulation. Not because of security but simply because of taxes. If you don't want to use regular fuel and replace, for exemple, 70% of the fuel by the filtered oil in which you have cooked your french fries, you can do it (as long as you have a diesel and as long as you don't mind the smell). However, you'll have trouble with the cops (fine, of course, but they might even be allow to take you vehicle away) who would have too investigate too far (except if they are sneezing of course:D ).
Nevertheless, despite that, when the gas price came up, the number of people replacing diesel by diesel mixed with oil or by domestic fuel, rose subsequently.

Svo
 

is NOT a new technology-its what the inventor of the diesel engine actually envisioned it running on .Not mineral diesel.

Older diesels will run on it and some newerr ones - with a little modifications - but not a lot of work .

Some mineral fuel should be added at intervals I understand..

So SVO - could well be the thing ,its been in trials in both world wars and many a resource full motor owner will have dabbled in it .

It could be possible -but the downside is you have to grow it and that it diverts land from food crops.

You are right about the downside but again, that will depend on where you are. It's in wide production around the world and you can find some natural sources almost everywhere.

All around the Mediterraean you'll find a fair number of olive trees that can be used for that purpose. In Mainland Europe, a number of crop is used to produce oil and it wouldn't be a problem to keep at least a part of this production. In Africa, you'll find palm oil. In other countries you'll be able to get oil from nuts. In all wine regions, you'll still be able to produce some kind of oil from the grapes without even lowering the food or wine output (you produce it from pip). In northern region, I wouldn't be surprised to see people using annimal grease (would it be possible from fish?).

Nowadays, that would be more difficult but in T2K, with the drop in vehicle number, it shouldn't be that much of a problem. The only things you need to produce that kind of oil are a tank, a flat stone, a wheel stone and something to roll the wheel (yourself, your wife, a donkey or some slaves).

For a historical viewpoint, try watching "The Grapes of Wrath" for the Okies vs. Locals interactions.

Resurrecting a 7 year old thread. That's got to be close to a record :D

Gotta agree, still interesting...
