    Here are the results of my second tank after the fuel guage update. This time I was careful to note exactly when each bar disappeared. Obviously the results are not impressive. The last bars now take a while to disappear, however the middle ones replaced them in their swift exit.

    My conclusion is that I would not recommend this procedure to others.

    70 miles - 1st bar disappears
    120 miles - 2nd bar disappears
    152 miles - 3rd bar disappears
    181 miles - 4th bar disappears
    210 miles - 5th bar disappears
    228 miles - 6th bar disappears
    234 miles - 7th bar disappears
    242 miles - 8th bar disappears
    286 miles - 9th bar disappears
    327 miles - low fuel light appears
    381 miles - I filled up tank and put in 8.46 gallons, the pump first shut off around 7.6 gallons

    Jen,
    I'm on my 4th tank post-TSB and concur with your conclusion. Others have had good results but frankly mine have been disappointing...almost to the point I start wondering if they actually did ANYTHING.

    Current tank...first bar dropped at 94 miles, second at 109 miles! Geez. The second half of the tank DOES seem a bit more reliable--close to 50 miles/bar, but I still start blinking way too soon.

    Last tank started blinking at about 430 miles, got 57.4mpg that tank...only got in 7.8 gallons of gas despite driving 25 miles + after it started blinking.

    I think that if you have TERRIBLE problems with your guage then getting the TSB done may be worth while, but if it's just eratic a little, but consistantly erratic and you can live with it then don't bother, it is not a perfect fix/cure by any means.
