A good quality Sewing Machine oil is formulated to do
a
similar job.

Not by a long way it isn't.

Agreed. In the US 3-in-1 Small Motor Oil is readily
available in a
convenient dispenser.

I tend to lump 3 in 1 in with WD40. They may both 'work'
but there are
other far better products for a single task. I'd not use
either on
anything important. Just to stop the garden gate
squeaking.


They're great for freeing things that are rusted-up. But I
entirely agree that I wouldn't think them suitable for a
turntable bearing. As has already been said a sewing
machine oil sounds about right.

Are there 3 things in 3-in-1? What are they?

If you want the oil to stay in place for 20 years, without
leaking, evaporating, wearing out or absorbing water and
whilst reliably continuing to inhibit corrosion, a modern
automotive gearbox oil is designed for just that purpose. It
may have a redundant property or two, but other options
mentioned, including "sewing machine oil" fall short in one
or more respects.

Sewing machine oil was (is?) common in households because
sewing machines need frequent oiling. Where does all the oil
go? When you oil a door hinge and it needs oiling again
after a year, where did the oil go? If you oil an outside
hinge with light machine oil, sewing machine oil, or
especially "3-in-1", why does it need oiling again after a
month or two, or after a few showers?

Gear oil will outperform those penetrating light oils by
miles. And it won't leak like a penetrating oil might. If
available gearbox oil is too viscous, motorcycle fork oil
would be good, but not so easily available in small
quantities for a few pence.

:-) I think it means three jobs with one product, marketing speak?

I just used engine oil in the end. ISTR the Project oil supplied with a
TT had a similar consistency.

I don't think there's one answer to the question 'what's best' - it's
always going to be a compromise between friction and (say) evaporation.
I know heavier oils have been criticised for 'noise' - I couldn't really
say.

I think that is correct.

So far as I recall it is essentially an oil mixture with added graphite
powder. I suppose it may also have some kind of surfactant, but no idea.
Don't have a can to see if it gives details.

Slainte,

That's the special 3-in-1 with added graphite. The normal stuff is just
a light oil.

10/40? For years, audiophiles have suffered the curse of
temperature-induced platter bearing drag variance. At last,
Rob's specially-formulated turntable oil maintains precise
viscosity even at high speed. Don't be caught out by global
warming...

Near enough, I hope. Inspect and report back in twenty
years.

Well, you may smile, but it was a tough call :-)

I've got a gallon of oil for a new Mini - flippin expensive 5/40
synthetic. Or some Halford's own oil for an old Mini, 10/40. I went the
boutique option.

IIRC, Cleans, lubricates and prevents rust. Of course that was the
original - later products might just use the name.

As a kid, I used it to polish rust off chrome etc on a bike, so my guess
is it contains a fine abrasive too. Which is the bit which worries me.

In the days when I used to ride a bike (Dawes Super Galaxy IIRC) to work I
used to regularly clean it with two sprays of lube/rustpreventer. I can't
recall the brand name. A three letter acronym followed by a number. Happy
days... except for all the white van drivers who seemed to want to kill any
cyclist they encountered and would aim at you and drive you off the road.

It may have just dissolved the oxide. But I've not seen or used 3-in-1 for
years so have no idea what it contained.

Most synchromesh car gearboxes these days use either engine oil or
sometimes ATF (auto gearbox stuff) although that's not to say so called
gear oil isn't on sale.

A car engine has all sorts of bearings and shear stresses, so my gut
feeling is a suitable weight one would be the best choice. As well as
being readily available in reasonable quantities at a good price.

Hypoid EP90 Gear Oil - used in differentials where the pressures are
much higher.

And I think it was a bit too heavy for my spindle so I might change it
for something lighter.
