The Oddities of the Fuel Bladder

I have grown used to the oddities of the bladder (not mine, though now over 50..well).

Anyway, the last tank, I was in a normal 55-56 for the tank.. I filled up, unusual for me, after a day of driving on one of the hottest days of the year (about 100f). I usurally fill up in the AM. Though it just went to 1 bar blinking, it took 11.55 gallons!!

Again, I realize that with the bladder & conditions, it can cause you to be way off on a single tank, but this was waaaay off. Now, on this new tank, I was at over 200 miles before the 1st bar even disappeared..

Over a few tanks, I will be my summer avg of 55 - 56 I am sure... but the two things were more out of line than I have seen yet.
