Dumb question guys.... I have only used DEF from jugs. When buying DEF at the pump how do you know when the tank is full before it overflows? Is there a handle on it like a fuel pump that automatically stops?
It's just a mini me of a regular pump handle. It clicks off the same. I have now filled at Loves and Pilot and both nozzles were clean LOOKING.
Just a FYI towing at 75mph in head cross winds 32,500# combined I got 225 or so miles per gallon use of DEF.
After being concerned about using DEF at the pumps I have no issues with doing so now. Saves me from walking into Walmart!
