Oh, that's right. But the industry have to struggle against
German tax regulations. German vehicle taxes for passenger cars
depends on cubic capacity, kind of fuel and emissions. In this,
regular Diesels, compared with gasolines same power, have near
doubled taxes. But the Diesel fuel is lower in taxes. You
have to drive at minimum 18 Tkm a year to get same prices on
DM per km. If you have more, Diesels are cheaper.

Another item are taxes about emissions. That's why all factories
developed the TDI and the catalytic converter for Diesels. Mercedes
developed a filter for particle emissions.

To reduce particle emissions you should use agricultural produced fuel.
I do this just before the two years emission tests and I got excellent
results until now. I can not give you the exact procedure how to
measure the effect of darken a special measuring filter, but this are
my last results on the TD (which is equipped with a CC):

Darkness top measurement:
Limit 2.00 per minute   Measurement 0.39 per minute

Darkness average measurement:
Limit 2.00 per minute   Measurement 0.38 per minute

Deviation of measurements:
Limit 0.50 per minute   Measurement 0.02 per minute

This tests are done at the highest rpm the engine will allow, actually
5070 rpm on my Golf and this test. But there is no load on the engine,
hopefully high milage vehicles will resist this nonsense test.
