I have a 2012 6.7 and don't care for the gauge at all. Above or under in a 5 gallon tank leaves some leeway and as mentioned you don't want to overfill as I don't put many kilometers on come September and with our climate here the def freezing could cause tank fracture. I know the heater works but not much help on my short commute.
I think the ram has an actual gauge measuring full to empty???
Love the truck but this is only complaint. Minor.
If you purchase DEF from a container I would recommend purchasing the Ford brand spout. It doesn't allow you to over fill and it also snaps into the fill port which holds it in place which is nice. Once completed rinse the spout with clean water, air dry and store it in the large zip lock bag that it came in for the next refill. It works like a champ.

Mine never says anything until the 400 mile warning. I put in 2.5 gallons at that point.

yes we all know that the shelf life is reduced with elevated temperatures

EXAMPLE: In 2009 the two hottest months in Phoenix Arizona were July and August. The average temperature for both months was 95F (35C), according to the data from the National Weather Service. The average daily temperatures for these months ranged from 104F (40C) to 85F (29C), while for
some days daily highs reached 115F (46C). For areas that see these average temperatures DEF shelf life would be 6 months.

I don't drive it enough to use it up all that fast sometimes. DEF that has gone bad in the tank pretty much means a tow truck to the dealer. Not a warranty item either.
I'm glad my Ford doesn't have the DEF Poor Quality problems. :W
And you should also know that DEF that has degraded will no longer do the job for which it is intended right?
So degraded DEF in ANY brands tank will cause problems..... The Fed simply won't allow a DEF system that is not functioning properly to let the truck run and pollute.... Even in your beloved Ford.
Hate to break it to ya.:B
Nothing earthshattering here...
I simply fill my DEF using the Motorcraft spout at every oil change. It's that simple... Oh, and no DEF poor quality messages either... Sorry wrong brand that's a GM thing. :W
Troy, you just refuse to get it.
I can and did used to fill my tank at oil change time. Then I found out how high temps GREATLY reduce the life of DEF.. And since I am in Phoenix AZ, where high temps are a fact of life, and I don't put that many miles on the truck, I decided it would be prudent to just put in 2.5 gallons whenever the warning message popped up. This will keep the DEF pretty fresh and avoid it going bad in the tank... It would go bad in a Ford tank too under the same conditions... I was surprised to find by reading here, that the Ford system won't allow for this. The tank MUST be filled all the way to clear the message.... That could be a problem for me and others like me.
And if your DEF should go bad in the tank, the truck will not run for long.. And it is NOT just a GM, Ford, or Dodge thing. It is the EPA regulations. Sorry, your precious Ford is not exempt..

Dog,
Yes we all know that DEF has a shelf life and yes we all know that the shelf life is reduced with elevated temperatures. Having said that, my point is the GM trucks are prone to DEF contamination problems and it's a pretty common discussion. Your environment is not unique and it appears the Fords and RAM's are not as sensitive to the DEF contamination like your GM truck so I simply fill and don't worry about it like you have too. :B
I suppose if I owned a GM truck I would partial fill to keep it fresh and avoid filling DEF from a truck stop like the plague.
