So as to not hijack another thread, I started this one, because the other one got me wondering.......(Not a good thing!)
Since my diesel truck and tractor are old, can someone tell me...
What happens if you run out of DEF and decide to go without it? Would it be sort of like removing a catalytic converter, and only show up at inspection time? Or will some silly little ole computer shut the machine down?
Might need some computer geek work arounds, if the latter is the case.
