This may be your take on things.

But it is hardly the responsible thing to do environmentally and as time goes - legally.

It also shows a misunderstanding of how effective diesel particulate filters (DPF) can be. A properly sized and operating DPF will trap over 85% of particulate matter and reduce efficiency far less than your proposed "several miles per gallon". The problem has been the first applications have been less than stellar.
