[Vwdiesel] Synth vs Dino Oil... yet again

[Derek]

 The other side:  diesels generate a lot of soot buildup in the oil.  There 
has never been a response to this issue in this newsgroup, from the Amsoil 
and synth enthusiasts.  Does oil analysis show soot buildup?  Does usage of 
synth oil prevent soot buildup?

Yes and No, in that order.  Unless you are burning lots of oil, I would 
still use synthetic.  More MPG and more dyno proven power.  Currently 
running 0W40 Esso XD3.  $21CDN a gallon.
