I can't believe I pulled this off. The best before this was just around 29MPG and that was combined city and highway with FE techniques. This was just keeping to the right lane with cruise control set to 100KM/h for 8 hours. To put this in perspective, last time I went to Florida, I drove about 80mph the whole way there and managed just over 25MPG for the trip.
