my 5th gen burns through the first quarter tank real slow. i usually get around 120 miles before the needle hits the 3/4 mark. the second quarter is quicker. i'm lucky if i reach 200 miles before i hit the 1/2 mark. the third quarter is about the same. the needle usually reaches it at about 260-275 miles. then the last quarter tank on the gauge is pretty slow, and i'll get about 80-100 miles on it. i typically get about 350-370 miles on 13-14.x gallons, and rarely let the gas light turn on.
so to recap....
1st quarter: 120 miles
2nd quarter: 80 miles
3rd quarter: 60-75 miles
4th quarter: 80-100 miles
pretty screwy..
