Any lower and you may cavitate the fuel pump if it is an in tank type. Since the fuel also acts as coolant for the pump running it to empty can cause premature fuel pump failure.
Just my personal experience: '94 F150, bought new, dual tanks, both with electric fuel pumps.

More often than not, I run a tank until she starts to buck from fuel starvation, then switch tanks.

2012 - 1994 = 18 years of doing that with no fuel system issues whatsoever.

To OP: Run it down to under 1/4 tank before filling up, and halve the number of fuel and time wasting trips to the gas station vs. piddling around with partial tank fills.

Run them as close to empty as you dare once and a while, best way to avoid water build up, is to not let it get started.

I used to do that too with my '95, never had any problems. I really loved that truck, I thought 18mpg city was pretty decent.

Was yours the 300 i6?

I run until empty and neutral coast to the nearest gas station.

Otherwise, I let it run down to the last 1 to 2 gallons (14 gallon tank) and then fill completely.

Suuuuure ya do.

While I have done it, I don't make a habit of it.

One time a bunch of us were out motorcycling and one guy's bike sputtered out of fuel. While still rolling down the road, I told him to put his passenger footpeg down. I pulled alongside and pushed his bike that way until the next gas station- thankfully, it was real close. My right leg felt like it was about twice the size of my left for a while after that.

One of the nice things about getting accurate consumption numbers and knowing exactly how far you can make it on a given amount of fuel lets one run down pretty low and still be comfortable with the quantity left in the tank.

That said the civic has a hesitation right after bump starting when the tank gets quite low. Once that happens it is time to refuel.
