When I filled up last week, my DTE was 544 according to the dash. I drove 540 miles and it was at 15 miles to empty when I fueled up today. I would call that very accurate, time will tell if it was a coincidence or if its just that accurate.
That is pretty accurate. Ah I see DTE, my car calls it range, same difference although it tends to go blank when it reaches about 80 miles so the last bit is guesswork. Yea I'm trying for an 800 mile tank, 773 is my best so far, it's a good range for a small car with an 11 UK gallon tank.
