I have an AU on duel fuel and the most I've ever gotten in city driving is max 350km ~ 58 litres, if I am REAL lucky (68 litre tank? Tickford Gas, read they use more fuel, but car is heavier too). With the price of gas now, that's around $30 a tank, and I do close to 400-450kms a week, so pushing $45-50 a week, don't know if petrol is better seeing it's averaging $0.85.
