Reset my trip meter on the way back from uni tonight for shits and giggles. 50kms of very smooth freeway, mostly 110/100km/h with some 80km/h roadworks. Bugger-all traffic and it was raining so driving style was very smooth conservative. Air-con on low.

Average speed of 104km/h with an average fuel of 9.1l/100km. Pretty pleased with that. If only regular highway driving was that economical :-/
