I have seen a Merc 300TD with 350000km on the origional
motor running on a mix of diesel and LPG. Apparently the
cleaner burn cleans up the emissions to return it to
acceptable levels.  I was told it is a common conversion on
tired trucks in europe.
Anyone out there run a Wasserboxer on LPG? I have had
several vehicles running on switchable petrol/LPG, greatly
reducing running costs. (LPG is half price). However several
converters I spoke to mentioned valve burning problems with
VW, (LPG burns hoter than petrol, and is missing the
lubricants) which makes the savings redundant.

Take care + have fun,
Ian
