ive noticed this too im not sure it's true of all vehicles as i pretty much refuse to drive anything thats not a yota (other than my sami) but first half of the tank seems to be more like 3/4 than a half milage wisefunny thing is i was trying to figure something strange out yesterday dealing with this..... i can get about 175miles town 190 highway on the first half tank. After the needle reaches halfway mark, the second half of the tank seems to go much quicker.
