Drain DEF tank after delete?

[powerstroke43]

What are you guys with deletes doing to the DEF that is still in the tank? I heard it expires so do you have to drain it or what?

I have been wondering this also. I think I'm just going to leave it. Might make going back to stock easier

I had that concern as well. Someone will chime in.

Mine has been deleted for about 6 months and I just left it in there. The low fluid light was on before I deleted it so I dont think there is much in there. I dont think it can go bad though.

I wonder if you could drain the DEF tank and use it for Water Meth injection kits?

It does go bad. Once exposed to air the Urea begins to crystallize and your left with a crusty tank with mostly water in it.

I've heard of this being done once, a while back.
