if its rural, then thats considered highway driving

i get 450kmz from 38L of 98 octane

generally thrashed driving, 80% in a fair bit of traffic, and tons of traffic lights


secondary back roads are a lot different to highway. some time in the next few mths i am planning a trip to sydney & i will then report what highway consumption is. it will definately be under 6l/100k.....but how far under is the question. but a round trip of 4000km will give a very accurate reading.
