Most Miles/Tank? - here's my best
 

531 Miles
325 miles to 1/2 tank fuel gauge (was a big miles # for me)
466 miles to low fuel light flickering (475 was on solidly)
16.0 gal to fill up (at same pump as before; tank cap. = 17gal by book)

I now estimate 'reserve fuel capacity,' after the fuel light, has 3 gallons, but easily enough for 60 miles ... and a 'lil bit left still (?)

1992 Accord EX, 5 spd tranny, 203,000 miles. A new car to me.
first 430 miles was on trip, easy high speed 2-lane roads, 60 and 65 mph speed limits.


Post up your longest tank range

98 accord coupe 5spd 4cyl: I havent actually filled the tank since ive owned it but i usually get 358 that is when the tank if filled a little above the half tank mark. ive only had this car for about 2 months.

On my 95 accord, EX, 2.2L, manual transmission:

496 miles until the low fuel light turned on. The trip was all interstate. It had about 180K miles at the time.

Typically fill up my 2000EX 5mt around 400 miles. Usually takes 13 gallons. I did drive >500 miles once, but I can't remember how much I put in.
