Before I moved, I had about a 25 minute commute to the train station each way (about 24ks) and averaged 8.5l/100. I found that most of the fuel burn was actually during the cold start program. If I went on longer journeys on the highway, I would easily see 7.5/100 and even as low as 7.2 on a really long trip (i.e. > 2hrs) (and no - I don't drive it at granny speeds, and I don't believe my speedo at 100 is actually 100 - if you get the drift). And on a trip to western QLD, i saw 6.9l/100... (I set tyre's before leaving). Now I have moved into BNE and we hardly use the car. When we do, it's to run up the road and is pretty well always running cold-start. We're now seeing about 12.5L/100... But I only fill it once every two months so I can't complain! I will tell you what got us by surprise was how we took .5 of a litre off our commute (and some may b sceptical, but we proved it twice - i know - not a good sample but good enough for me). We almost never wash our car (we sit inside it - not outside). I know - I've probably upset most of the forum members by saying that. So, needless to say, it got absolutely filthy and covered in dust/grime/oil/bugs e.t.c all over. We spent a day cleaning it and waxed it, and immediately noticed a drop in fuel consumption on our commute. Again, over a period of about three months, this slowly crept back up, and we cleaned/waxed it again... Fuel efficiency gain of .5 again! In fact, I it was closer to .7 for the first week, but that could have been a number of factors that gained the extra .2 on the first week. There is something to be said for keeping your car clean!
