The looming shortage of the diesel fuel additive AdBlue looks to severely limit the distribution of food stuffs and other commodities.
It could see our trucking industry grind to a halt
Particularly as China has banned the export of urea a main ingredient.

We just sent some to South Korea!

Some people say that diesel engines can be adjusted to run without it. Other people say that it can't. Most of us don't know. We do know that it it's addition to fuel was part of the environmental hysteria that will lead to our doom.

ttbn,
Seems that some trucks can shut the requirement down but they will require Commonwealth Government permission.

The Law of Unintended Connsequences strikes again!

Diesel is now literally indistinguishable from unleaded, a right-out pain !

AIUI AdBlue is not a fuel additive but an exhaust system additive to reduce NOx pollution. All diesel engines can run without it, though some diesel trucks may be configured to be unable to run without it.

South Korea has been severely affected by China restricting exports of it, so it's good that we're exporting it there. But Australia may need to do something to prevent a similar crisis occurring here next year.
