Not much difference between diesel and oil.

Perhaps, but there is a world of difference between the tolerances of a fuel
injector pump and an oil pump.

Not much difference between diesel and oil.

Not much other than viscosity, flow rate, condensate content,
contaminants filtered, use of the product being filtered and reason for
being filtered in the first place. :-)

Hmm, would be interesting to find out the viscosity difference of 220F
motor oil vs. cool diesel fuel. I'd guess they are pretty similar with
similar flow rates and condensate content. The contaminants filtered
would obviosly be different but the reason for filtering in the first
place is the same... to rid them of particulants.

Well, different condensate content since there isn't likely to be much
at 220F.

Now now, be polite.

I was trying to be. Note the :-).

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

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.

True. But that's a red herring since it's not usually the oil pump that
wears out due to dirty lubricating oil.

As for stirring up the crud, one guy told me he shoots a jet of air around
the bottom of his tanks. Has a small L-shaped copper tube on an air hose,
and with it tied to a dowel/rod pushes it to bottom and "aims" it around.
He'll them sometimes just let the thing bubble away while polishing to help
keep particulate matter in suspension.


But he is only stirring up one baffeled area in the tank unless he has access
plates to each area.

No offense, but how many of you have actually seen the insides of a well built
marine fuel tank?
