Why
not?

Maybe because with the amount of diesel most of us sailors burn it just
ain't worth the effort.

a friend of mine has a '05 Dodge cummins diesel, and he strains his
used motor oil and mix's it up to 15% and has had no problems that I
have known of. he told me that he can go over that, but the exhaust
gets "smokey"

I posed just this question (albeit not WRT Cummins) recently in both
this and other forums/mailing lists, etc; I have a fuel polishing
system which would be a piece of cake to Tee with a valve to the sump
line I use to suck out the oil and run it through the polisher on the
way to the tank.

Do a bit of archive-looking in this and Seven Seas Crusing Association
forums (ssca.org) and the sailnet morgan and other lists with me as
the author.

Way too many responses to try to duplicate here, but the scholarly
response (ignoring the usual opinions of those who haven't tried it,
and have no scientific background to fall back on) was that the acids
won't be happy, the particulate/heavy stuff will coke out on your
exhaust, and other reasons not to do it (marine being different than
truckers and perhaps heavy power boaters).

Other respondents cited friends and a couple of direct experiences
which said they'd been happy, and one even provided several links to
military directives to do just that. However, as none were
sailboaters with minimal use and lower exhaust temps, my election was
not to do it, as much as it's a nuisance to recycle the oil.
