[Vwdiesel] Rabbit droppings # 66 ----- ( a matter of choice )

[James Hansen]

Chris, any oil test result available for early tdi with soot recirculator
(egr) running extended drain intervals?  Wondering how far it has been taken
with that engine. I know of a few that have run industrial engines 1-2000
hrs on a change using oil analyses as a guide.  These were older direct
injection, but not egr equipped engines.
