Forgive me if the answer is obvious but I'm curious. My 2012 hybrid's tank capacity is listed as 13.2 gallons which I think is the same for all 2012 models. My low fuel indicator kicks in when the remaining "range" on my car display says that has just under 25 miles left. I always fill up the tank within this 25 mile timeframe and I notice that I only fill around 10 gallons each time. Where is the mystery three gallons? I get that some of it is in the fuel lines and some is in the tank but does that all add up to three gallons? Is the range actually displaying a very conservative number so that when it says 25 miles left, it really is a bit more? Please educate me here.
