Gas tanks can be anywhere from 1 gal up to 1,000 gallons. Mine holds 17 gallons. It depends entirely on what vehicle you were talking about. You could find the information for yours in your owner's manual. Run your car until it is just below E. Fill it up full and look at the pump to find out how many gallons you put in. Round up, and add a gallon. This method is a total estimate, because fuel gauges are set to read empty with a few gallons in the tank. It also depends how much full can sit in your fuel lines or in the pump. Mine holds 14 and it reads well below E when I have over 2 gallons left. read your owners manual
