On my canoe trip this weekend, we went to Algonquin park (access point 17), we took my friends 2006 Honda Accord (4 cylinder), we had the cruise set to 120km/h on the major highways, and were speeding through the gravel roads, A/C on fan speed 2. Managed to get 850km on the tank, 6.8L/100km. Trunk was loaded with 3 large backpacks, and the other half of the back seat was loaded as well. Damn Accord with those seats that don't fold. I wanted to take one of the vans, but he felt like taking the car...
