There is no trash/water/debris etc on the bottom of the tank that the fuel system will pick up when the tank gets low. I know this for a fact because I have actually seen inside the tank on many cars, including my G37 just 4 days ago. Nothing in there but gas. Running the car low on gas does not "burn up your fuel pump". The pump is inside the tank itself and is in the gasoline. Which is always cold no matter the temperate outside. There's always cold gas running through it to cool it, as well as floating in the cold gas. If you run out completely, the car will shut off from not having fuel long before any damage to your fuel pump occurs. If everything is functioning properly, you won't run out of gas just because the DTE hits zero. As you discovered, when the cluster gauge and the DTE computer tell you the car is completely empty, there is still anywhere between 2 to 3 gallons of gas in the tank. The most miles I've personally driven is 66 after it hit zero. Our gauge and DTE algorithm is very conservative. Even if you do run out of gas completely, it wont harm your car. Just don't repeatedly try to start it with no gas in the system. Put some back in the tank and it will start up and run like normal, no harm done.

I speak from personal experience. I have been in the tank of the G37 several times. My car is over 7 years old. I've had to go in the tank to service the fuel level sending units twice to get the gauge to read correctly.

Not having enough fuel in your vehicle in an emergency is very important in case of unexpected power outages and hurricanes.

Here in NJ we have had sudden road closures for hours after serious accidents. Even being a few miles from home with an empty gas tank can have severe consequences during very cold weather and a road closure from an accident.
Running out of gas is not an experience I've ever had.

This is a lesson that many learned here in NJ during Hurricane Sandy.

With severe weather predicted for later today I filled up my tank this morning even though the needle was slightly above the quarter mark

I'm new to the thread and also a new 2010 G37 6mt owner. I'm having the type of issue as Erik and I think I'll try the reset the battery but I just want to be clear. When the dealer filled up my car, the range meter said I had 189 miles to E. I know it's not right but I want an accurate reading. Is resetting the ecu what I need to do?

Thanks guys and loving my car
