On a recent trip to Bunbury I checked the fuel usage, the car had 3000K on it. The majority of the road is dual carriageway and as flat as (most boring road you will ever drive), 100kph section on cruise was 7.6, 110kph was about 8.5 and when I was up in the hills it was around 12. This was behaving myself as my conscience was in the car with me. Around town it is generally 12-14
