Anybody able to chime in with real world example of how many miles past 0 DTE the x5 can actually drive?

I plan to drive my just fixed x5 down to zero (with can of gas in the trunk of course), then open the tank and see how much is in the surge tank.
I've driven my E53 down to the point of lean misfire several times, just over 20 miles after the DTE displays "0".

I'm still on the OE pump (over 200k miles), even running the DTE below 10 miles before almost every fill up (almost 25 gals).

I think the 10 oz of Lucas UCL/fuel system conditioner added at every fill up has helped pump life.
