Sounds good in theory, and as Steve says his TP filters get a lot of gunk out of
there. But I still have no confidence at all that they are not shedding gunk
too.

Actually, 'depth' filters sound TERRIBLE in theory.
Use a what?
A toilet roll? A kitchen roll? Gimme a break.

It is in practice that they do best.
Over the road operators brag repeatedly about astronomical mileages -
some of them practice only filter change and filter bowl oil make up
only... no complete oil changes.

Winnowing through the stuff from true believers, it looks like depth
filters can carry a much larger particle load and can filter to
smaller particulate sizes. They will certainly trap water, though I am
unsure how far that reduces the filtration efficiency and/or increases
particle transmission.

Depth filters have plenty of background: I ran an aircraft rated depth
filter made of deep cloth layers for five years in a light airplane.
The brand was "Winslow" You bet the price did not compare with a
kitchen roll however.

About 4 years ago there was a couple guys on the group who managed truck
and heavy equipment fleets. They swore by the paper filters (paper towel
or TP) and used them on their own personal trucks. You could probably
find the threads on google.

I believe that was for OIL not diesel.

Ahem...you meant mineral lubricating oil, rather than
mineral fuel oil?

THe Gulf Coast paper towel filters are popular with trucker for
extending the life of lubricating oil which is what they were originally
intended for.

Yeah, that's what he means.
And check out the tolerances in a "mineral oil" lubricating pump verses the
tolerances in a "mineral oil" fuel injector pump.
Then maybe you will grasp why proper "mineral oil" fuel filtration is more
critical than "mineral oil" lubrication filtation.

While you're checking out tolerances that are critical for "mineral oil"
lubrication filtration, don't just stop at the lubricating pump. Look
at the bearing surface tolerances of the engine.

You are off-beam, in my not so humble view. But then if you prefer to
be addressed as "Capt." I can suppose that your opinion is not that of
an engineer?

So, do you have opinions on brain surgery for me to grasp too?
You have one those as well, after all!

You are off-beam,

Perhaps. But my point is that just because fuel oil and lubricating oil come
from the same base material does not mean that they are filtered in the same
way with the same filter materials or to the same standards with no thought as
to how they are being used.

in my not so humble view.

That makes two of us.

You'd be right.
And I believe it was engineers who assured the Captain of the Titanic that it
was unsinkable.

Yes.
Try not to have it done if you can.

True.
Thanks for noticing.
