A Extra 4 Gallons
When I fill up my 2006 Honda Odyssey at the pump I usually put in about 16 to 17 gallons. I was curious one day and tried to add extra gas after the gas pump stopped. I was able to add an extra four gallons. WOW!! This gave me an extra 110 miles.
If the gas foams in the tank it will fill up like champagne... try not using the auto trip and holding the spout up with your hand so that the tip touches the wall of the tank... works like tilting the glass...
When u over fill the tank over flows and u actually waste gas. U are supposed to stop St the diedy click to avoid waste .
4 gallons when the light comes on. Know what you get... the one who said 60 might be right BUT Do you really want to run it on that end of the gas tank... I don't.
