All i know is when i was younger I did a drive 270 miles roundtrip (cruising at 75mph) about 10 times over a 3 month period, and every single time i had 1/3 tank left like clockwork....but to clarify something, the gauge only shows 1-14 gallon mark (so if its showing dead zero , if means there is a gallon of reserve left). so for the math above, its 13/4 = 3.25 gallons.....so 65miles/3.25gal = 20mpg (not that it makes a huge difference but just being technical)
