Why does the gas guage plummet after the 1/2 mark?
Yet another quirk among the f-body generations. The main reason for this is that the gas tank is sort of shaped like a ‘V’. Because GM was to cheap to make an accurate mesaure, the guage just takes the depth of gas in the tank. As gas gets lower down in the tank, it’s used faster than at the top of the tank due to the smaller volume. Thus gas is used quicker. The half way mark is actaully only 1/3 full. So when the needle starts going towards the ‘E’, find the next gas station because ‘E’ is means EMPTY.
