[Vwdiesel] Oil opinion?

[James Hansen]

Nick, you'll find that most of the synthetic oils for sale now are 
blends of group 4 plus what they call a mineral base stock, or the ones 
that stand out as less expensive are group 3 hydrocracked stuff, 
"synthetic" by order of a judge. It's pretty annoying.
That said, the research in the olden days into synthetics and racerboy 
stuff was that a blend of your ordinary dino oil plus as little as 30% 
pure PAO ester would give you oil with nearly identical properties to 
the synthetic.  This is essentially what is being marketed now.

Terry, a diesel rating for oil indicates that the soot handling 
capabilities are higher than the gasoline oil counterpart.  You would be 
  much much better off using a diesel rated oil, and changing it.  It's 
the additive package that dictates the soot handling capabilities, not 
the source of the carbon chains the oil is made from.  Use a gasoline 
oil, synthetic or not, it may not handle the soot load, and your engine 
accumulates particulate soot internally, rather than it staying 
suspended, and eliminated when the oil is changed.
