You can, we have had trucks towed in from people doing it. A local municipality put DEF in the diesel and diesel in the DEF, the truck had a service body on it and somehow they made the mistake. We have had a customer who has put 5 gallons of DEF in the diesel tank twice and proceeded to drive the truck. Both were very expensive repairs not covered under warranty.
