Default Fuel Polisher as oil change device?

What does your engine hold, 1 gallon, 1 1/2 ? For that
small amount, I wouldn't worry about it, but then, I'm not a
scientist.

What about the 'acids' they say is in the old motor oil?

worth it. Of course, now it's $25.

The 25-30/whateverbux, while interesting to me, isn't the

issue. It's
getting rid of the waste oil. Over in the Seven Seas

Cruising
Association forum where I posted the same questing, Rich

H, presumed to
be Hampel, previously seen in these parts, said,

didactically,

"Simple engineering answer:
expect the lubricating oil (heavy fraction) to not fully

ignite in the
combustion chamber, thus vulnerable to form a massive coke

deposit
downstream in the exhaust manifold and mixing elbow.

You're not burning
Bunker-C /#6 but lightt weight #2 in your engine. If your

engine were
set up to burn a heavy oil (which it cant) then adding

lubricating
fuels would be OK; otherwise, not. Asphaltic tar will burn

too; but,
you wouldnt put 'tar' in the tank either."

Yet, I'm being referred to many sites, including some

governmental (see
prior discussion about Algae-X for validation modus

[modii?]) position
papers, which say that doing so is the best way to dispose

of the
stuff, with no mention of issues in exhaust streams.

OTOH, I have also seen some reference to aggressively

mixing the stuff
with fuel before re-insertion into the fuel tank. I'm not

at all sure
what that's about, but I also would hazard a guess that

oil changes
would happen while not cruising, and my fuel polishing

system would do
a very good job of recirculation of stuff which came down

the same pipe
as the other polished fuel, and thus mix well...

So, keep the info coming. I'm pretty close to thinking

it's a good
idea :{)) but being talked out of it for sound engineering

practices
aimed at engine preservation would be OK, too.

In or out of 'em, it doesn't matter. Nothing seems really

that's the charm of it.

not."
