How close to being totally out of fuel have you been?

I've had a Mun lander run out of RCS fuel within 10m of the orbital station. Bob just collected all the science and abandoned ship, completing the rendezvous by jetpack. I eventually retrieved the lander with a resupply ship. I'm no stranger to sending the crew to get out and push too.

Not counting times when I've had to get out and push (which has happened more times than I'd like to admit, including once when Jeb's jetpack needed refueling 7 or 8 times before I got my periapsis low enough), I once did a rescue mission without RCS, and by the time the rescuee climbed aboard, I had just enough fuel to lower my periapsis to about 65km.

Gotten out and pushed way to many times. Also why waste fuel by letting them go splate into Kerbin. Little thing called part count and most of the time never enough to use chutes to get a softish landing. I know I have gotten very low before. Just nt sure how low. I know I have had to use mono to lower my orbit enough to get back to Kerbin when out of fuel.

I dunno the dV, but I have finished the mid-course with a fraction of a unit of oxidizer left when returning from Duna once.

The original plan was to not have to use the ERV (this was a mission I actually brought an emergency return vehicle on for some unfathomable reason) but I underestimated the return costs and did not refuel the transfer stage fully (thinking I could actually make it) so I ran outa gas on the ejection burn. I had to decouple the ERV and make the remaining transfer burn. I guess that ERV was not as good of an ERV as I thought. :P

0.11 units of RCS fuel after an Eeloo (or somewhere in the outer solar system at least) return.

Or this one: I realized that I did not have enough fuel to return a Kerbal from Moho, so I aimed for Eve. I had exactly enough fuel to get into an Eve orbit before running out. A second launch brought the Kerbal back.

My first rover lander on the Mun had its engines cut off when running out of fuel while landing, however it was perfect because it was during the final stage of landing where it was only about two feet off the ground and it should have engine cutoff anyway. The lander had a re-orbit stage though with just enough fuel to get into orbit, so I don't know if it qualifies.

I had once where I had to wait for two hours while my ship slowly got decelerated with an AP half way to the Mun, and a starting PE of ~60 km. Increase time warp, see it slow down on atmos reentry, turn on phys timewarp, turn it off once out of atmosphere, increase time warp.

Once I had 12 m/s left when I docked to Jool Station (50000 km orbit). It is nearest I can remember. I had some monopropellant also.

Couple of times I have used all monopropellant just before docking.

My favorite all time was an rover probe I was landing on Tylo, it run out of fuel a couple of meters over the surface this disintegrated the laning rockets leaving the rover ready to roll.

Design was one rocket on each side of the rover extending below it with landing legs, below the rover it was a drop tank who was dropped during decent, this was also where the rover was mounted to the transfer stage.

has had some SSTO rockets running out of fuel during the landing back at spaceport and running out of fuel during the braking but still able to land safely.

One spaceplane run out of fuel during deorbit burn, I was able to land on the plain west of the spaceport so it was not an full recovery but still.

I've had a couple of trips back from Moho to Kerbin in my Supership where I've been about as close as it's possible to get to the line.

1. Ran out of rocket fuel, switched to rover RCS.

2. Ran out of RCS, switched to satellite ion engines.

3. Nearly ran the xenon tanks dry, finally got an intercept with Kerbin.

Phew!

On a visual survey of Kerbin mission my aircraft ran out of fuel heading towards the last target and I did a dead stick landing and just managed to roll into the final zone. Other than that I've had plenty of get out and push moments and done a Mun return mission with a Kerbal X that was a little tight on fuel.
