After I installed my stage 1 tune from EOC, with the DEF still enabled, I started noticing heavy DEF usage. Now because of this I've always filled up my DEF tank right around the halfway mark. Sometime after that, I started noticing that when I was nearing the halfway marker on my DEF tank level, the Jeep would sometimes tell me that I needed to add DEF or I was going into limp mode within 500 mi. Now I would go add DEF and I only get about 2.4/2.5 gallons in there before it was topped off, and as we know it's a 5 gallon tank.
Now I just assumed that this was because of the tune. It started happening about the same time it definitely eats DEF like crazy now with my racing tune, they have to be hand in hand...
Or maybe not!
During my last Amazon maintenance fluid purchase spree, I saw this product from Hot Shots Secret, a DEF additive. I figured screw it, I'll order two bottles, worst case scenario they don't do nothing.
I get my DEF from Bucee's at the pump, And because of my tune and the extra usage I usually add anywhere from 1.5 to 2.4 gallons every 3 to 6 weeks depending how much I'm driving.
I think it's supposed to be 2 oz of this stuff every time you fill up the DEF tank, but I've just been indiscriminately squirting it in there and just guesstimating how much is 2 oz for about 3 months now. Today is the first time in 40,000 mi that I have been able to get my Jeeps DEF tank gauge under the halfway marker...
So at this point I'm just going to keep driving and smashing that skinny pedal, and see how I can get the gauge to go before it starts complaining about needing DEF. If I get down to a quarter of a tank, I'll probably grab a 2.5 gallon box as a safety in case it decides to go into limp mode early.
I guess there was crystallization on the sensor probably? I've added DEF additives to the tank before and I've never had this kind of response from the system... Even if you guys haven't had any issues with your DEF tank yet, I would recommend getting a bottle and using it. Do like I said, what's the worst that can happen? Cleans up some of that crystallization crap? Not a bad idea!!

I'm probably going to buy a box of 12 of these here shortly. Even if I get my stage 2 tune sometime later this year, I'm not going to install it for a minimum of 2 years from now. So I'm probably going to keep eating up DEF for quite a bit longer.
