I will have to play with the setting to be sure. According to total usage I used 7.3 gal for around a 30 mile trip +-. I know w/ my old Merc, I would have used at least twice that much. I don't have a 6 gallon tank, I guess I will have to keep watching, obviously much better than before. I am fairly sure it is set for US gallons. I tried to make sense of the manual and it is difficult for me to understand what they are saying/doing. Thanks for the heads up.
