I'm somewhat of a gadget junkie.  I just bought one.  Should arrive in a
couple weeks.  The item number came up as "LUBRICHECK2", so that confirms
this is the second generation (Oilyzer).

My Scirocco has not had an oil change in more than 5 years. It will be
interesting to see how that oil checks out.
