Yeah the big truck guys will give me crap all the time and tell me these lanes are only for big trucks, well they aren't, I have my cdl, and both the def nozzle and all big truck nozzles for diesel fit in our receptacle,
Ive always filled up at the flying j or pilot since new. I always run into the red, then go top all the way off.
Funny thing is I deliver 55 gallon drums of adblue def to the dealerships and it comes out .50c higher per gallon even in bulk. and the 2.5 gallon jugs are $15.00 higher per gallon at the dealerships.
I did find a new def at Walmart for $8.00 per 2.5gal made by supertech, compared to $11.00 for the adblue at walmart
