Empty Light Comes On Way Too Early!
I've never really pushed my luck in my 2009 Camry SE 4 cyl but I've determined that the tank empty light comes on WAY too early. My light comes on consistently at about an eighth of a tank of gas and I usually put in about another 65 miles before the needle is actually on "E". Once there I usually fill up but I usually wind up being able to put in at most 15 gallons no matter how I baby the gas nozzle or how many extra clicks I give it. Whenever I'm on "E", I always have a minimum of 3.5 gallons of fuel left in my tank. Now, assuming I could actually get every drop out and burn it until I run out of fuel, I should be able to go another 163 miles after my empty light comes on or another 98 miles after the needle hits "E". Driving conditions apply heavily here though and since I got my Camry broke in I've been averaging 28.5 miles per gallon across a whole tank of gas and I have a fairly heavy foot (though I'm trying to work on that).
So you have a heavy foot. It could be that when you are lying to everyone about how great you imported car is you defecate in you pants. This unspeakable stuff slowly slides down your leg and arrives in your shoe. This will explain why you have a heavy foot. Get some help fast, before you turn into a homo.
The light doesn't mean much. If my car is empty and I put in $10, the light doesn't always go off. Or it will come right back on after I drive a couple of miles. But if the indicator drops enough to show space below the empty line, it has coughed going around corners. I figure it must be time to get gas. I have also been using my trip odometer instead of the gauge as much, of course that changes with the price of gas. You other 2 people are idiots(above comments).
