The DEF pump nozzle at Seven Feathers RV lane in Oregon was so crusted up with white crud that I just hung it back up and stopped up the road at the next Wally World and got a Peak Blue box, just like the other 3 or 4 that I have used in 12K.
Same here, I've only filled up once at the pump and I had to wipe the nozzle off first. For no more than I buy I'll continue to buy it in a jug.
