At work, we have used motor oil for general machine lube. On these machines
there are a lot of bronze bushings, cast iron bores that have slow rotating
hard shafts and slides in dovetails and the like. Often an oil cup or
button get overlooked and if overlooked often enough, there is a failure.
One-shot systems aren't feasible.and, no doubt, PM needs improvement. There
are more than 50 oil points and as many Zerks for grease. I use "Slick 50"
grease and it works very well.

So, the best lube is the most forgiving. At home I started using STP as a
general lubricant, it's recommended by the manufacturer of my newest
reloading press and I like it's properties so far. Can I see any advantages
to using it on my machines? Is there a bad side to it? It's very thick and
I wonder if it will flow into where it's needed. Does it bring any thing to
the party other than viscosity?

Apart from high viscosity, it brings ZDDP

http://www.thecloroxcompany.com/prod...ltreatment.pdf

From the MSDS it doesn't look as though it has any other additives (these
would normally "show up" on the sheet).

ZDDP is an anti-wear additive: the following lifted from Imperial College
(London) who know about this sort of thing.

"Zinc dialkyldithiophosphates (ZDDPs) are the most successful lubricant
additives ever invented. They were introduced over 60 years ago, have been
in continuous use ever since and are still being employed in all current
engine oils. During the last decade however, concern about the impact of
phosphorus oxides on the exhaust after-treatment catalyst, especially its
ability to reduce NOx and particulate emission, has necessitated a
progressive reduction in the permitted concentration of this additive.
Parallel to this there is also a tendency for oil drain intervals to be
extended, which has resulted in a general increase in the level of
dispersants employed in engine oils. Unfortunately, some nitrogen-based
dispersants used in engine oil formulation are antagonistic to ZDDP".

In the UK power industry it is sometimes used when installing steam
turbines. This involves lowering various shafts into half-bearings and
twiddling them to align couplings, etc. The high viscosity means it doesn't
drain away too quickly. The oil companies generally don't approve in case
its additives interfere with "their" additives.

It looks fairly safe to me for your applications, but you should always be
aware that some oil additives (e.g. EP additives) can cause corrosion of
copper-based bearings, and if you mix different types of oil especially from
different manufacturers the additives can "fight" (though I believe this is
rare).

It's well marketed so probably expensive for what it is. But if you are
using it in modest quantities convenience probably counts.

Way back when, we used STP to install press-fit bearings. Over a
period of a day or so, the STP would get squeezed out of the joint,
You could then press it apart and find no trace of the lubricant. This
was a good thing for this application, but it would suggest that you
wouldn't want to use STP in high pressure applications.

If you use STP, you'll have to add oil to it for it to be considered a
lube. I warned a shadetree mechanic about spinning a bearing when I
saw him wiping his fresh rod and DIPPING his main bearings in the
crap. Since I was just attending UTI and a punk 17 y/o kid, he didn't
listen until 4 days later, when the recipient called from
Nebraska...with a spun bearing. I think STP's owners saw enough of
those to finally start adding actual _lubricants_ to the can, but I'd
make sure if I were you. This was my experience in 1972.

Googling msds stp: The Clorox Company. No ****! Owns 409, Glad,
GreenWorks, Liquid Plumr, Tiles, SOS, PineSol, and ArmorAll (who owns
STP). Amazing. OK, they've totally reformulated it since then. It's
mostly mineral oil now.

STP, I learned back then, clumps oil molecules so they don't run off
the bearing surfaces when it's sitting overnight, keeping the engine
from wearing and making things much more slick. I switched to Slick 50
when it came out but haven't used any additives for a couple decades.

STP reminded me of getting honey on my hands way back when. Does it
still do that with the new formulation? Sticky, never seems to quite
wipe off?

Just to add fuel to the fi WAY back when, we owned a 1959 Austin
Healey Sprite. Used a 4 cylinder Austin engine. Being poor, I did all
the servicing, including oil changes. I had heard so much about STP
that I decided to add it to the oil. Well the next oil and filter
change, I found all my STP in the oil filter cannister. The actual
filter material was cotton felt material. The STP would not pass
through it and the filter effectively filtered it all out of the oil.
Never used STP again.

I hate to pull answers like this out of my ass,

way oil might be a better choice.

How about doing your PM better?

That's the real problem.

Scott Logan has stated more than once that he uses way oil (Vactra #2,
I think) for everything except geared headstocks. And he oughta know.
