How low have you let the "range" go? How low can it go?

I always try to refill when I get to 50 miles left on the digital range estimator. I've gone as low as 30 before needing to refill. Has anyone run it down to 0 (and how far were you able to go afterwards)? During longer trips through more sparsely populated areas I find myself getting range anxiety so it would be nice to know what the LCs true range is. I drive a HE to the extent it makes a difference.
 
I've run it to zero and drove another probably 20 miles. It always takes about 20 gal to refill when the light comes on which leaves about 5 gallons of fuel left.
 
As I have an aux tank, I actually did a test to empty on the main tank once. The rang-o-meter is conservative and many of us fuel up when close or past 0 miles left, before looking for gas.

My findings support the consensus that generally there is ~4gallons left when the range-o-meter reads 0. The range available really depends on your use case and mods. Assuming 10MPG for the worst (maybe when towing), to 17MPG when hypermiling on the freeway, could mean a reserve range of 40-68 miles range left on level ground.

Note that the wild card of off-roading or grade could change the equation of whether the fuel pump can truly reach all the leftover fuel. I found that as soon as the fuel pump drew any air, it stalled immediately, assuming fuel rail pressure collapsed. So there is a level of risk when there's relatively less fuel remaining, to handle conditions.

Jerry cans can be useful. Not because one would regularly use it, but it adds margin and insurance to comfortably use more of the main tank capacity.
 
I've run it down well past 0 before. Happened the one time I decided to leave my jerry cans at home. Thank God I was on the downhill side of the mountains to the nearest fuel station. I've had a couple close calls but seriously thought I was gonna be walking the last few miles on that one. I don't leave the jerry cans at home anymore.
 
I don't run my vehicle empty. I have a LRA and just picked up a jerrycan. HE or not makes no difference.
 
My best fill up to date has been 22 gallons.

To answer OP, usually fill up when at or before range goes to zero.

Zero range usually leaves me roughly 5 gallons left in the tank.
 
I fill up at the quarter tank mark.
Yes, this is too often, but I’m sick of those bux-pucker moments when driving through the west and that next town you have been aiming for doesn’t even have a gas station.

And even with this strategy, I’ve still taken it down to 0 and then gone about 20 more anxiety filled miles when gas stations were closed or something.

(I do now mostly carry a rotopax and am working on getting a second gas tank).

Generally what I do as well. I’ve been considering an LRA forever but reading about all of the issues that people have with them regarding fumes and whatnot has me on the fence. The jerry cans have been fine
 
Regarding the fuel remaining in the tank at 0 miles, is it correct that the remaining fuel is designed to cool the fuel pump?

If so, are there any real world failures based on repeatedly running the fuel at a too low level and a failure resulting?

The LRA is a game changer for certain, but like most things it has a challenges to work around. I think through trial and error they may be a very good, if not near perfect modification for remedies for those that have had issues.
 
Atypical but I've run the tank down to 23.9 gallons. Typically the light comes on at the 19.5 gallon mark. I was well below the Empty line.

I usually run my truck 50 miles after the light comes on. I hit the button on the trip odometer to track it. Most I have ever put in my truck is 21 gallons.
The miles to empty on this truck is a design flaw. I’ve had trucks that very accurately tell you when you about to run out of gas. These trucks should come from the factory with a 30 gal tank.

Same, same, most for me is 22.5, agree, agree, agree.
 
Nice to know.

I ride to empty and it fills only 19 gallons. Never knew the LC has 22+ gallons in it. Thanks for the info fellas 🙌🏼

It’s aprox 25 gallons. Makes it even worse.
 
93 liters = 24.56 gallons US
seems 23.9 is the record so far... leaves maybe 0.66 unusable?
19.6 is when my light comes on, so approx.. 4.3 gallons usable left at that point.

NOTE The 24.5 gallons is for the 2016

Myself I like to know gallons left as I could be different conditions and mpg, towing, not towing, offroad, flat road, mountains. etc.

FWIW, the manual for my 2008 states that the tank is 25.4 gallons.

I usually fill up when it gets close to "0" and it generally takes between 19 and 20 gallons.

0 miles on the meter is about 50 miles left for me.
 
Run to zero and start looking when on the Interstate. Usually run about 20-30 more before the pucker starts....right there with everyone else at about 22.5 for fillup....oh plus 12 more gallons .....
