so i pull into get gas and i am at the top 1/3 of the red zone on my fuel gauge I go in and pay $20.00 for gas at 1.83 a gallon for 87. That should have been about 11 gallons. Well i get in and start the car and the fuel gauge just keeps going and pegs itself all the way out. So how many gallons are factored in for the red zone? Am I to believe 5+ gallons or so and thats guessing the red was actually like 2 gallons. Anyone know?
