Does regen happen when low fuel light on?

Just curious if the regen goes on when the low fuel light is on? Was driving last night and the low fuel light turned on but I was no where near a gas station. As I was getting closer I knew I was in range according to the reading but was close and thought, if the truck went into regen and used up the fuel, I'd be screwed and not make it to the gas station. Anyways, made it to the gas station with 9kms left on the reading. So, does the truck actually go into regen when low on fuel or is the computer smart enough to know not to do that? Also, anyone go past 0kms/miles on the reading and not run out of fuel?

Thanks in advance.

There was a thread, on going past the miles to empty a year or so back. There were people who did it by 20 miles or so. I think at the end, it was agreed it was not a good idea because of the damage to the injectors if you run out of fuel. I don't know about the regen after the light.

lol, I was in the exact same position 2 days ago. I was looking for diesel and I had 14 miles to empty. I thought, hopefully I don't start to regen. I always set my trip B to monitor my mileage between regens and I was right at the usual mileage. Sure enough! Regen started... I found diesel a few minutes later.

That is a big reason why I no longer let my truck get below 1/4 a tank. When I first got my truck, I learned on a road trip that it will regen when you are low and what was thought to be a normal situation turned into near panic as I drove to the next diesel stop.

Its never fun to put in 30 gallons of diesel into a truck that has a tank that holds 30 gallons.

Good thing is I'll never have to do that again. My dpf fell off in my garage a while back.

I can tell you from experience it will regen with the fuel light on and you will run out of fuel a hurry. I have done it twice, but fortunately made it to the fuel pump with the truck sputtering. Not god on the injectors,but what can you do when it says 30 miles til empty goes into regen and 10 miles later the truck is sputtering. Un like my 08 my 2010 is dead on with the fuel gauge. My 08 gave me a little cushion, not my 2010.

Great contribution.

To the op, I've ran mine to 2miles to empty but no further. I'm sure it would still regen tho, and then you'd be in trouble. Like dimsum says, don't let it go below 1/4 if you can help it.

Or, get a Titan Fuel tank and not worry about it. I'm getting a titan tank for mine to extend my range beyond 275-300 miles before a DPF delete because of warranty worries. Keeping it bone stock until 100k miles. Then, by that time, I'll have enough saved up to probably get A LOT of stuff done to my truck such as studs, EGR delete, etc. all at once.

At least, that's the plan if I don't trade for a new F-150, lol.

I literally watched my miles to empty count down a mile every 10 seconds or so. I thought I might have had a computer glitch until I realized it was in regen mode. Now I never go below 1/4 tank.
