****, IDIs are probably the only trucks you could run on DEF, these things run on anything
DEF will crystallize when mixed with diesel. That is one of the main reasons the repair is really expensive on vehicles that have been mixed. Also, FYI, it is just under $12,000 to have a 6.7L Ford fixed when you do that. That consists of all new inector lines, injectors, high pressure pump, IPR, low pressure pump, pretty much everything except the fuel tank and the main fuel feed and return lines. And it all has to be done to maintain any engine warranty.
