I sample my oil and sent for analysis. Costs
$20 but the knowledge of whether or not the oil
is good as well as what else could be wrong with
the engine is invaluable. For anyone who cares
about the environmental impacts, not changing
the oil is better for the environment too. I
use an over-sized oil filter and the very best
amsoil marine diesel engine oil. This
particular oil has a high TBN of 12. IIRC, TBN
stand for total base number, you know base...
The opposite of acid. As acids build up in the
oil the TBN goes down. If the person doing the
analysis sees that the trend suggests the TBN
(or any of the oil specs) will be too close to
zero before the next oil change, they modify their recommendations. Â

Keeping moisture out of the oil is another key
to long life. A block heater keeps the oil
dry, the rings from sticking, the cylinders from
rusting and the boat warm enough to prevent the bilge from freezing.

Regarding sitting - after winterizing the engine
will sit until spring. I doubt that is really
such a big deal although yes these things
donât like to sit. The boat sat for 2 years
before we bought it and the engine has run well
without issues or leaky seals or anything since
(had to replace a bad fuel pump and glow plug
relay). So 5-6 months over the winter doesnât seem like a big deal.
I donât generally put a lot of hours on the
engine <50/year and this year I have only put
about 25 hours on the Westerbeke 20B2 in
Wisper. We are hauling out on Monday. I have
been pondering if it really makes sense to
change the oil and oil filter at that point (per
the change it every fall on haul out
philosophy). Or is that is a waste of resources
and oil (more from an environmental perspective
then $ costs) and I should just wait for it to reach 100 hours to change it.
Any thoughts?
