My Smiths gauge goes really, really slow from full to the half way mark, then stays there for a while, then drops really, really fast to the empty mark. It's better than nothing, but I rely on my odometer. Basically what I do is try and fill it up when the odometer hits 100 and under no circumstances go past 150 miles. Although in theory I could go 200 miles on a full tank of gas.
