You clearly know nothing about boats or engines, but you know a heck
of a lot about stalking. **** off.



Cap'n J, is it running good?

MOST important is what happens to the LEVEL on the dipstick...does it drop
a little?

Diesel engines USE oil, some more than others. Anyone you know who has a
diesel that doesn't use oil (they usually brag about it), either has water
intrusion, which is easy to spot, or fuel intrusion past the rings, which
isn't until it's bad.

Oil analysis is used to EXTEND oil change intervals on engines that use a
LOT of oil, big diesels using gallons and gallons. As yours is not
anywhere near this category and an oil change is so cheap, screw all that
and just change the oil every hundred hours OR SIX MONTHS, anyway. It
doesn't break down in a hundred hours or 6 months sitting there full of
fuel and acids and water so just changing it is fine....UNLESS THE LEVEL
RISES!..which is BAD...

They crank fine at 25,000 hours if you do this...(c;

It can also be used to find out what is wearing out. If you perform
periodic oil analysis and keep a record you can see the bearings and
rings wearing out. Whether this is of interest on a pleasure boat is
debatable (it is on airplanes) so the advise to change the oil and
filters every X hours probably results in lower costs and very
possibly longer engine life.
