TOS S32 Lathe Oils?

Hi to all at PM. I recently became the new owner of a 1974 TOS S32 that was nearly scrapped. After lots of stripping, cleaning and painting it's ready to be fired up, that is once I find oil for the spindle gearbox etc and the apron gearbox. I have the manual, but there is no mention of the type oils to use. I have contacted TOS in Czechoslovakia regarding the oils to use. They recommend Shell Morlina S2 BL 5, TDS here: https://hand.net.pl/wp-content/uplo...d_Kingdom_Shell_Morlina_S2_BL_5_en-GB_TDS.pdf

I believe the crucial part is that the oil is Viscosity Grade 5

Unfortunately this oil is not available here in Australia. I have tried to contact Shell Australia. Useless. No reply. No technical phone help.

I visited Mobil, who were very helpful. Velocite 4 is their recommendation. Guess what? it's not available here in Australia. Mobil suggest blending Velocite 3 & Velocite 6 50/50, to give a version of Velocite 4. These oils are available here. That's OK but I will need to purchase double the amount of oil to create what I need. If that's my only option then I accept that.

Apron: Oil type unknown.

Any positive help or suggestions would be very much appreciated. Thanks.

Here's a few snaps of the old girl...

Its old. Put in what is available - like Velocite 6. This is ISO 10 which is very light oil

If apron oilers actually still oil ways and slides put in Vactra 2 - and if the ways and slides are not getting lube put that on manually liberally - including back end of cross slide and its screw

A good thing about antique machinery - some oil is way way better than no oil

Velocite #6 is very light...It is specified for Twin Disc torque converters in the turbine section.. Velocite #10 is what I used for the spindle bearings in my 16" Southbend lathe...Velocite #6 is about like kerosene or diesel fuel as some Twin Disc torque converters do in fact use diesel fuel for the turbine section.....Velocite #10 is about like 3 in 1 oil..

Nice looking job, handy tool the baby TOS.

FWIW I'd be guided by what John Oder says, ….he's been round the block a few times


WARNING don't worry if the headstock get's ''quite warm'', IME TOS lathes tend to run a good bit hotter then most - it's what they do

Thanks for the informative replies, they're much appreciated.
My gut feeling was to use the Mobil Velocite No.6, but thought it was best to check first with people that have real world hands on knowledge, (you guys) Cheers. So yes I will use Mobil Velocite No.6
I've taken note of the headstock heating up, not a place to leave a micrometer. Thanks for the heads up.
Would the Velocite oil also be OK in the Carriage / Apron? It does not oil the ways, only the gears etc. It has a cam driven piston pump, that pumps oil up to a small reservoir that is then felt filtered to supply gravity fed copper oil lines to various gears and bearings. The photo shows what was discovered when first opened up, it was stripped and thoroughly cleaned with kerosene and is now awaiting fresh oil.

Thanks again for taking the time to help.

You could try it - see if it finds ways to leak out where something heavier may not

Thanks John, that's good enough for me ��

A quick update. I went with the Mobil Velocite No. 6
A$147 (U$98.50) for 20L. Everything is working as it should without any leaks.
Thanks again to all that helped.
