DEF isn't needed in older diesels, it's a new green energy requirement to reduce the amound of soot that comes out of diesel exhaust.

I don't know if you can run a modern diesel without it (I would think so, just more polution).

This is another self imposed shortage due to the green agenda.

More shortages caused by the green energy movement, of course!

So there is a workaround that could be implemented quickly.

The Biden admin will never allow it, they want the shortages and damage to the economy to continue.

But too my point..
