my dash gives me an option of looking at average mpg, hours used and total fuel used.
My total fuel used is about 9000 gallons, and total hours is about 1000. How can this be? This means i use 9 gallons of fuel every hour its used? Even at 80 mph this puts my economy at about 9 mpg. But the same display says i do 17.6 mpg
anybody know whats going on?
