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+...

My truck burns DEF at the rate of a gallon per 750 miles driven. If I drove less than 5,000 miles in total during the summer months with 100 degree temperatures I would avoid refilling the DEF tank until the fall.
DEF deteriorates from heat and sunlight so in hot weather it is best to buy what you need at the pumps at truck stops and Shell gas stations with diesel and not buy the 2.5 gallon containers - you also pay less that way.
