(Disclaimer -no expert! )I use synthetic in my diesel car and truck, and would
on the boat as well if not for the way that moisture tends to accumulate due to
the way we use them. The very short runs encourage condensation, so it of
course gets changed every fall like most everyone does. It seems like synthetic
would be a waste. So I use Rotella on the boat.

What do the experts say about synthetic oil in diesels?

most of the engine oils that are available today have plenty of additives
that get bad or ineffective after about 6 month in the engine. So if you are
using the engine year round, you might consider changing the oil twice a year
(at least once a year) and if you are using it less (even if you use it for
just
a few hours each year), change it annually. For us, Northern folks, this
usually
mean changing it in the fall. From what I read around, there are people who
change the oil in the fall and again in the spring. I don’t, but I can
understand the reasoning behind it.
I hate throwing out the good engine oil after some 25-50 h of running time,
but this is a cheap insurance for the engine.

Diesel
engine oil is supposed to look black - it's like that a half hour after you
start the engine - by design.

If it is cranking at the usual speed, then the
compression might be off a bit in one of the cylinders. This can happen if
one
of the piston rings has got stuck over the winter. I would warm up the engine
good and hot and then take for a run. Run it fairly hard for a couple of
hours
so long as everything appears to be ok. That should get the carbon out, if
there is any, and it might loosen up a seized ring.
Black smoke is a sign of a rich mix, but it means
little if you have just started the engine after a period of cranking it for
a
while.
If you did not change the oil last fall, then now
is the time to change it. I don't know why, but I have found that lubricating
oil sitting for a while in diesel engines is more likely to go bad than in
gasoline engines. Maybe it is climate dependent, but that has been my
experience limited though that may be.

Listers,
I find I'm having a harder time getting the engine started and seeing a
little bit of darker smoke when it does turn over, as compared to last
season.
Once running, everything seems fine -- temperature, water flow,
revolutions, etc.
Any ideas or suggestions?
Usually, my solution to engine problems is "get the jib out."
All the best,
Edd
