| Great information! I do have one question though, many sources I checked indicate the solubility of urea (the main ingredient in DEF) in water as high and experience I've had with cleaning out crystallized injectors seem to support this. That said, of the DEF is already saturated, which could happen if the water evaporates off, that would prevent any crystals from dissolving. Just curious as to what experience you've ran into to experience it not wanting to crystallize. | |
