[Shop-talk] Lubricheck

[Randall]

Never heard of it, but I'd like to hear more.  Kind of sounds like it is
just measuring resistance, which could be done without the $40 gadget.  I
don't doubt that the resistance changes, but I'm not certain how well it
correlates to actual oil condition.

A bit of poking around produced this site, which talks about some other
simple (and mostly free) methods of oil testing.
