Changing the oil every 100 hours isn't much of a chore. My engine
only holds 2 gallons. 110VAC polishing systems would be a pain
when at ancor or under sail. Can't justify running the genset for
hours on end. A nice 12VDC pump drawing just a few amps
can be supported easier on PV and wind.\\

OK, in that case I would look very closely at the Alfa Laval
unit. It is very small, 110VAC low power. No filter beats a
centrifuge for use like that.

If I really wanted to do it right I would put one on the
lube oil as well.
