The manual says we've got 20 gallons of room so I assumed there were always three more in reserve. I was averaging like 34 mpgs over the whole tank and decided I had another 90-100 miles after it read empty. I went ahead and drove another eighty eight miles or so and filled up. That time I pumped 20.001 gallons.
When a car starts to be on "empty" there is usually a reserve, 1-2gallons. it depends on how big the tank is, for us I would guess you would have a good 2gal of gas left or maybe 3. It's so that you can try n make sure you can get more gas before going dry

!! my car does it as well lol, a never-ending thirst till she dies
