DEF Blue Adding
Just wondered whether a person might "top off" the DEF tank instead of waiting for the warning stuff to light up and mess with my comfort level? Does it hurt anything to do this?

Just be sure you have a system in place to ensure you don't overfill and leak down the side of the truck. Or clean it quick.
I just filled my Ford using the Ford spout on a TerraCair DEF bottle. It took 2 of the 2.5 gallons, then stops. Leave the spout in, drop the bottle below the spout, excess fluid goes back into the jug, when done, remove the spout. Easy, peasy.
I've overfilled mine and not worried about wiping off the side of the truck. It dried a kind of white flakey film that very easily washed off at my next car wash two weeks later. Why do caution about quickly cleaning it?
