it was the first real highway drive with the 335 for me since I got it, today I went to Toronto then back home, left at 5:30am and back at 4:00pm, exactly 1200km, at the destination I put 55 liter for 600km, same back home, what's funny is speed going was average 120km/h and back was 135, but average consumption was exactly the same, is it downhill back from Toronto to Montreal?
