    My truck stays on full for 30 miles then suddenly drops to 3/4 before your eyes.

    On my truck:

    At 21 and 20 gallons in the tank, the needle is above the full line.
    At 19 gallons, the needle is on the full line.
    At 18 gallons, the needle is 1/4 down in the space to the 3/4 line.
    At 17 gallons, the needle is 2/3 down towards the 3/4 line.
    At 16 gallons, the needle is on the 3/4 line.

    In terms of miles... at my 17 mpg:

    0-17 (and under ~30 miles), above full line.
    34 miles, on full line.
    51 miles, 1/4 down the space to the 3/4 line.
    68 miles, 2/3 down towards the 3/4 line.
    85 miles, on the 3/4 line.

    Forever sideways and smiling :D
    I'm fairly close to these numbers also. The farthest I've pushed the tank was just over 19.1gal, 344mi @ 18mpg.

    It is nice when we get 17 or more MPG, isn't it!?

    Here are my entire gauge scale findings:

    FULL: 21 Gallons
    F LINE: 19 Gallons (down 2)
    3/4 Line: 16 Gallons (down 5)
    1/2 Line: 12 Gallons (down 9)
    1/4 Line: 8 Gallons (down 13)
    LIGHT ON: 4 Gallons (down 17)
    E LINE: 3 Gallons (down 18)

    The above figures have been consistant, within 1/2 gallon +/-.
