You have a lot of good points pocket I agree with you. I guess I'm just a little worried that I'll get stuck on the side of the road if the system starts to run low and start a count down when I'm hundreds of miles from any practical help. It just seems whether it's incredibly cold or too hot you can't really haul the stuff with you due to the fact it will degrade how much so I really don't know? thanks for the information I'll try to let one tank run low and see what happens take care

I just got a propane injection setup that I'm gonna install soon that will make my truck run at 100% efficiency which will make it so I barely use any DEF. The trade off is I have to fill up the propane tank(s). But, it also gives it a good safe boost in power and a big boost in fuel mileage.

If the new Flash reduces the Regen to 5 - 8 minutes, and only takes 1 mpg off when its doing it, that seems better than the old scheme which went off every 500 miles or less, took 20 - 25 minutes, and knocked 5 mpg off during.
Be interesting to hear from others that have gotten the flash: what do your regens look like now?

When I had my Nox sensor replaced the Ford tech reflashed my PCM back about a year ago. This flash I believe was the one that changed the regen strategy from utilizing the drivers side bank to all cylinders. I also noticed that the regens went from ~10 miles to ~12 miles to complete.

Not even kidding. You can't burn a gallon of DEF per tank. That's going through more DEF than any manufacturer states per cycle, no matter how much you tow. It's off the charts and something only trolls post.

There's absolutely no way anyone can burn one gallon of DEF per tank of diesel, no matter if it's Ford, GM, or Chrysler. Unless you're some master tow hauler with something wrong with your truck.

True... not even a after market tank. I guess I was giving the guy the benefit of doubt.

Well, i made the run from Ft Worth To Romney West Virginia and back as per my other post. 2015 with 20K miles, 3.31 gearing...
After a 20 hour drive, switching drivers of course, we made for a hotel in Morgantown West VA. After getting up and running out to the race track. we got back in to head for the local hotel in Romney. My exhaust fluid warning light came on showing i had 500 miles left and it began the count down. after running back and forth between the track and the hotel over the weekend, we ran down through Winchester Va and stopped at Walmart to pick up some DEF fluid.
Now, i had added fluid shortly before making the trip but did not top off. It did take the whole container but i hadn't checked the level but was concerned that i had to add. So i bought 2 jugs. I began pouring the first jug in and it overfilled with less than a gallon added??
The warning light continued to appear until we stopped and started a few times. i made the 1400 mile trek back to Ft Worth with no issue and the exhaust fluid OK shows when i do a system check. so, why did i get a warning with less than a gallon low?
Not a big deal but had me nervous that i was going to have limited speed once the count down hit zero and we planned( and did) to drive straight back. First and only problem i had with this truck. we had 2 dirt bikes and gear in the back, ran 75-78 mph and had mpg avgs from 18.1 down to 15.7 depending on wind and terrain. Overall avg was 17.2 between all tanks (calc mileage and total gallons used). the computer was accurate as well.
How much def should I be using anyway?
Sorry for the random thoughts, been a long weekend!

The difference is that I just replaced my def heater and module. ('15 F250 6.7 500K miles)
I drove the tank to the 99 miles warning so it would have less fluid (less weight) when removing the tank. After removing the tank i emptied the remaining contents and rinsed out the tank with more horse **** just to make sure it was as clean as possible.
All went well but on start up i got the dread 50 to 50 warning.
Can I clear this by having autozone read and clear, by disconnecting negative battery posts, or by starting the engine several times?

I take it you did a complete fill once you got the tank back in. If so, then give it some time. Otherwise you will have to have it reset with IDS.
Get the ford filler spouse and use that for the refills. The ford spout will not let you overfill the tank. Also won't spill.
I always run mine down the less than 200 before fill up. Mine will reset with 2 minutes of starting the truck back up. In 7 years I have never had an issue with the def system.

My 2015 has had a new heater tank installed at about 40-50000 miles as old heater element broke and counting down, prier to this I had a falls message which dealer cleared, since I have had 2 instances where display start to count down to empty but when I go to fill it won’t take 2.5G before spilling over and had to have code cleared again, I don’t top op until under the half full and always from pump at truck stops, so there are many different gremlins at play.
