Interesting. my truck just turned 26K miles, as with you about 10K was towing, but only 18K combined. so far I've used somewhere between 20 and 25 gallons of DEF. about because the first 4 tank fills were on the dealer, and they were refilled with the free oil change. twice I had to add 1 gallon before the oil change, but each case I'm estimating the dealer added about 4 gallons. and I just added 3 gallons this week.
