[C320-list] Engine Oil

[Pat Ireland]

What Jeff said - East Coast Yanmar rep agreed synthetic was acceptable for
our 2001 Yanmar.  He made the caution that the engine may leak and may use
more oil.  No leaks and no noticable consumption increase.  Note - manual
says not to use synthetic.  Yanmar recommends synthetic for some engines and
not others.  That Turbo may be one of the recommended uses.  We use the
Mobil One "Diesel" synthetic and are happy with it.  But the oil is changed
on a normal schedule for the reasons that Jeff mentioned.  I want the
improved lubrication that I believe synthetic oil provides, but want to
remove any potential moisture or acid contamination on a regular basis.
YMMV
