Port Dover (ON) to Charlotte (NC) 1,200 km
Started off on snow covered highways until close to Buffalo, then cold and wet until heading south away from the lake. Rain and fog through WV and then temps didn't ride until over the Blue Ridge Mountains. Windy the entire drive.
6.2 L/100 with the roof box, cruise set at 115 kph (once away from the snow/ice) and multiple bursts to 130 kph not to clog up the passing lane. Many transport trucks were going 120-130 kph, same with most other cars/trucks.
