'Bout the same. I'd allow for 25 miles. I've done over 30 once or twice, but that's really pushing it...
Plus, y'know, it's not really a good thing to use the very last drop of fuel in your tank; it increases the risk of crud (or water) from the bottom of the tank getting into your rinjectors.
The less the better!!! I just keep pouring it in. It's the main vice in my life. If the worlds oil is going to run out , i want to die knowing i had my fair share.
Once upon a time, in the darkest, deep night in torrential rain in the middle of nowhere in France on the way to the Bol, I managed 47 miles on my 748SP with the fuel warning light on. I can tell you I was worried and doubly relieved to when I came across an open fuel station on the autoroute.
