How accurate is 'miles remaining'?
I'm curious what the record for 'mileage remaining' is.
I.e. What's the most number of gallons you ever put in your tank at once during a fill up, and how many 'Miles remaining' on your tank was at the time.
Is zero actually empty? Or is there buffer room?
It seems like if I calculate MPG * gallons remaining, it seems like there is buffer room.

once the light comes on, your pretty much at around ~4 gallons remaining. Thats like 30-35miles remaining on the dash. with that information, i assume that once you hit "---" it will be about 2 to 3 gallons remaining.. but i wouldn't take it so close to empty.

your car holds 20 gallons of gas, and should average approx. 20 mpg, reset your trip meter when you fill up, and see. Mine has been erratic as hell, and not at all reliable. My car is currently, and has been for the last 5 days, at the dealer for this very problem, along with the gas guage not working correctly. If they are able to fix it, I'll post up. This is my 4th trip for this problem.

We all do it and I would think each individual car is a little tiny bit different, but one thing is for sure, running on E all the time, your fuel filter will be full of all the rust and crap that lives at the bottom of your gas tank.

For the OP, I have experimented and the reserve is approximately 3 to 3.75 gallons left in your tank after distance to empty is "------". How far you can go depends on your driving. The distance to empty isn't voodoo, it's a mathematical function of how much fuel the sensors read in your tank x the current MPG the computer has determined your car to be getting. To test it do this: drive aggressively on a city driving cycle so your MPG is 16 or so on a tank. Then fill the car up completely. Your DTE will be low - maybe 264 or so (16 MPG x 16.5 gallons). Fill up after driving all highway miles at a reasonable speed when your MPG is 25 or so. Your DTE may be over 400. Yes I have tried this.
I have driven over 57 highway miles after the DTE was "----" without running out of fuel though I believe I may have been seriously pushing my luck.

I drove 55+ miles (maybe 65) on "---" and still had .5 gallons left on the highway. I was actually testing the limit that day. I got a bit scared halfway because I didn't see any gas stations around!

That is simply 100% false. It's not even close to being true on a modern automobile. Unless someone has intentionally introduced foreign objects, there is no rust and crap in the bottom of your tank. I have dropped lots of gas tanks from a number of cars and it's just not there.
