DEF - Usage
Just on my maiden voyage with my 2014 Ram 3500 Diesel pulling 13,500lb 2009 Cardinal 34'. Pulls like a dream very nice to drive however after 1,000 miles I have gone through 1/2 tank of def, 2.5 gals...

Diesel Exhaust Fluid is 32.5% high purity urea (you may recognize the faint scent) and 67.5% deionized water. The cheapest stuff at Walmart for $7.88 per 2.5 gallons is just fine, particularly since it has the American Petroleum Institute (API) stamp right on the front of the container.
Here is a link to a Q&A document on DEF put out by Cummins. It has answers to many of the questions posted in this discussion. Note that it is really written for big rigs, not our pickups.
