Have people put DEF in their diesel fuel tanks accidently? I've been wondering what would happen if that mishap occurs?
It's been a real problem in aviation as some jets have experienced engine failures after def got into the jet fuel, which is similar to diesel fuel.

I work for a truck OEM, and after seeing the complexity of the systems in place today for emissions I have no desire to own a diesel vehicle. What a shame as pre 2010 it seemed like diesel was the only way to go.
I suppose if you don't keep vehicles long you can be like luxury car owners who buy cars like BMWs, just trade it in for a new one before the warranty runs our and then their high cost of maintenance isn't an issue for you!
