DEF question
Hey I am still in my learning phase of about diesels to see if I want one for my next truck let alone need one. I am here in SLC I currently drive a company vehicle. I see where DEF goes bad in 100+...

Test Data on Thermal Stability of DEF from my DEF Technical Library:
This test data correlates well with the Arrhenius equation for the rate of DEF hydrolysis.
Note that in the vehicle's SCR system, the water in DEF rapidly evaporates in the exhaust stream resulting in fine urea particles which then decompose to ammonia which reacts in the vehicle's catalyst to convert oxides of Nitrogen to Nitrogen, water, and CO2.
