I currently have 3.0 gallons in the DEF tank according to Torque Pro. Once I see the DEF is "less than half full" in the message center, I fill it up at a truck island when it's convenient, it usually takes 2.5-3 gallons. I always wait until it's less than half never sooner. Also during winter weather I try to fill the tank just prior to freezing weather but not so full if fills the tube.

Army Ret, I don't want to drag this thread down a rat hole, but have to comment, I am the correct age. Tricky Dick saved my life, they did the lottery in 1972 for the class of '73, my number was 4. While I vehemently opposed the south east asia police action and protested hard against it, I always advocated for the folks that had to deal with that BS. A number of my friends gave the ultimate sacrifice. For those that don't know, people would sacrifice their kids, they would strap explosives to their body, have them walk up to a platoon of American soldiers with their hands in the air, when the kid got close enough they would explode the the kid. Like 7 year olds, it was an awful awful situation and those that were there should be honored to the highest extent.

I have not and don't have any desire to do so. Last thing I want is a confused DEF system puting my truck into limp mode.

It's not a pop-up message, you have to go into the information menu>system chech to see the DEF status. I always record engine and idle hours at the time of fuel up and exhaust fluid status is right above it.

Thanks, I figured that. I'm gonna have to start and maybe do that. It sucks to be this **** but it is what it is. Another great tip thanks dirt. I use Trip A to record miles since last fillup, check to see how close truck mpg is to calculated and also gallons used. Trip B just keeps ticking up since I bought it.

If you get to the 500 miles till limp mode you will get a message in the info center. I had the 500 mile till limp mode. I filled the tank and the message wouldn't go away. I tried everything even unhooking the batteries for a hour. to no avail. I had no choice but to hook up my 5th wheel and hit the road. 150 miles till limp mode the message went away. I was in Michigan on a trip with my wife. We live in Ca. so long way from home. Never had a problem again. now I know what to do. Just fill the tank and drive it and it will go away

Yep I'm well aware of the draft. I remember signing up for possible service when I was in high school... Class of 84. My hat's off to you guys.
