Default Need a bacteriocide for oil

Diesel folks,
I took apart the apron on a used lathe I bought and the sump had gobs
and gobs of gobs of gelled oil. Even though the sump in the apron is
not supposed to get any water in it I'm sure some gets in from
condensdation and maybe coolant leaking in somewhere. So this tiny
amount of water must be enough for the type of bacteria that eats oils
to live fairly well. I have washed out the sump with solvent but I'm
thinking that any bacteria that can eat way lube will probably like
stoddard solvent too. Will the bacteriocide used in diesel burning
machines and oil burning furnaces kill the bacteria in my machine
sump? I'd like to just rinse the sump with bacteriocide laden diesel
oil, drain, dry, and then fill with way lube. Anybody think this would
prevent the rapid regrowth of the gel?
Thanks,
Eric
P.S.
Why is it called way lube? Is it just because it is so good? I mean
it's not just lube, it's WAY lube. Just askin'

I would rinse the sump with bateriocide diesel and not bother to dry the sump.
Diesel has a little lubricating properties and a little diesel should not be a problem.

You are probably right Dan. I'm just wondering if it will be effective
or if I should just refill with new oil. If I had an oven big enough I
would just bake the thing at 180 degrees for a few hours and be done
with it.

Yes, although my guess is the gel is likely due to the petroleum molecules reverting back into longer chains over a long peiod of time, and or evaporation of the lighter fractions. If the problem is indeed bacterial, I would soak overnight, bacteriocides generally need to be in contact with the target organism for some period of time to be fully effective.

Thanks,
Eric

It's a throwback to early ship building, ships are still commonly launched under gravty, down wooden "ways". Early machine tools were of similar construction, greased wood beams. Oftentimes the matinging wooden blocks were lined with thin metallic strips in order to reduce friction.

The bacteria that eat oil are usually anaerobic; oxygen kills 'em.
It could be a LOT of things. Best plan, is just to remove anything in the
sump that comes out in a slotted spoon, and unclog any filters.
In the old days, one might some carburetor cleaner to the oil and
circulate it to do a 'clean-out', but that's VERY BAD unless your ventilation
is top-notch.

Naturally, if you dislike the look, or history-mystery of the lube, it's time to
recycle it and maybe pay attention to the filter/pump/manifold/pipes

A long time ago, I read something about Houghton selling a oil with some iodine added. I don't think it was cutting oil, I think it was to lubricate stainless against stainless. So I rummaged around on the internet and found a patent of two about using iodine as a biostat and also improving the performance of a cutting oil. I also found references that said that iodine is very corrosive to some metals.

So I would probably buy some biostat rather than trying a do it yourself solution.
