The only thing contaiminated Def will do is maybe clog the injector that's it! No more of a concern then the fuel you buy!
The DEF is injected on the front side of the dpf not in the engine! The pumps at all stations have filters on them just like the fuel pumps do.
Man we do have a bunch of chicken littles on here.
