I learned a similar lesson with a race bike. I learned to keep the tank full when parked between race weekends.

On the other hand, filling your gas tank is a complete waste of time, so I prefer to do it as rarely as possible. That means almost never filling up with a range of more than 20 miles showing.

I've let the range drop to 0 twice on my 991.2 and based on the amount of fuel added and the listed tank volume, there was still about two-thirds of a gallon in the tank.

Anyone know of potential issues for running the tank dry? I know on some other makes the fuel moving through the pump keeps it cool, and running dry risks overheating.

I know that running your tank dry can cause the pump to suck up any dirt/debris at the bottom of the tank and clog the fuel filter.

Prob won't happen in newer cars as there shouldnt be too much build up but I've def seen it happen before in older bikes.

Thanks for this. I've got 800 miles on the odo on my 991.2 GTS, but got in the habit of running to empty and beyond on my f82 m4. I definitely would have run out of gas.

My car doesn't show single digits remaining, once I get down past 10 miles remaining I get "--".

I keep the tank pretty full, and fill up often. But, there are a few drives that I do, that the fuel warning light turns on (50 miles remaining). This happens to me because on some of my drives (Wisconsin farm towns and country roads) there is not 93 octane available, only 91. So I need to push the car further till I get into the next larger town. Yes, I know 91 is OK, but given the choice, I'd rather have the 93 in there.

The upside, if I elect to take on the 91 octane, it's usually available in that area without ethanol.

Perhaps the severe downhill stance was the cause? The low bit of remaining fuel was at the front of the tank and not near the pickup?
