I reset the trip quadrant values at start. As of now they read:

Miles: 255

Distance to empty: 153

Avg fuel (over the 255 miles) 37.5 mpg

This is telling me, if I understand correctly, that at 37.5 mpg I can figure on 408 miles for a 12.4 gallon tank.

Except there is a discrepancy:

37.5 mpg for 12.4 gallon tank = 465 miles. Now I did notice the total miles available (miles traveled + miles remaining) increase as my average fuel economy increased. So perhaps over the next 153 supposed miles to empty, I would actually get (465 calculated - 408 displayed = 57 miles) 207 miles (153 + 57). Assumption being that the vehicle stays at 37.5 mpg.

Likewise, something that looks approximately correct:

153 miles remaining at 37.5 mpg = 4.08 gallons remaining. The fuel gauge

*appears*to be approximately 1/3 scale, but yes, that's really a guess. (4.08 remaining / 12.4 total) = 0.329 which is close to 1/3 tank remaining.

What are my Mk3 colleagues experiences with the calculated miles to empty values? Close? Way off? Conservative (i.e. 150 miles to empty, but really 180 'to be safe')? Aggressive? (i.e. says 150 miles to empty, you better not push past say 100)?
