DEF is consumed at a rate of about 2-3% relative to the amount of fuel you are using. This means between 1.2 and 2.0 gallons of DEF will be required for a vehicle with a 65-gallon gas tank. If you have a five-gallon DEF tank, DEF should be replaced every third or fourth time you fill up.

What happens if you over fill DEF?
If it is “capped off” by overfilling, the DEF within the tube crystalizes. Crystalized DEF prevents air from entering the tank. This means the pump can’t move the fluid out of the tank and do its job of breaking down the NOx. Habitual capping off chokes engine performance.
