European engine manufacturers would like us to use MTBE and ETBE in our fuel as it's a great octane enhancer, it adds oxygen into the fuel, increases the flame front temp and is generally good for the engine performance and exhaust emissions. It's banned in Qld and WA because it can cause (and in Europe has caused) some serious ground water contamination, so because our fuel is shipped nationally it's effectively banned nationwide. Our fuels are clean, they just don't have some of the herbs and spices allowed elsewhere, and that's probably a good thing.
