There’s no reason why you couldn’t bring it in and get it registered for road use. To bring it in you need an import permit from the Department of Infrastructure and Transport in Canberra. That allows you to land the car, after you need to consult your state authorities to get it approved for registration. Rules vary from state to state, but it is most likely that you would need a report from an approved engineer.

GREAT. The Escort is a fun car and great to learn about mechanics and driving. They're easy to work on, there are many parts available and they make a good little club competition car. However, it's old and won't have the modern safety features, but I would say go for it.

THERE shouldn't be any problem in running your car on ethanol-blend petrol, as long as you understand it is still an unleaded petrol and needs the same sort of valve protection it needs on unleaded. The ethanol blends we are seeing are low in ethanol and there's generally no problem with them. It's only when you get to quite high blends that you could encounter problems. In terms of increasing fuel consumption, I don't know of any additive that will increase your fuel consumption on standard unleaded petrol.
