All4One, the US gas price is 84c/ltr, less 8c taxes = 76c. (only 3.8 litres in a US gallon).
Take our petrol price of 1.32, (local BP yesterday) deduct GST of 12c, = 1.20, less duty, 38c, = 82c/ltr - fairly comparable seeing most of ours is imported rather than produced locally and our volumes are a lot less.
