I think there are factors other than viscosity. Surface tension, which may or may not be related to stay-where-you-put-it-ness?
@Roland Ranfft is a big fan of Tillwich because Tillwich publishes oil specs and Moebius doesn't.

I've been told that while you are learning, the difference in oils are mostly irrelevant compared to your technique. Some watch schools just have students using a single all purpose oil while they are practicing. After someone has gotten the practice experience from servicing 200 watches, the different oils will make a difference. Until then it's much more important to be practicing your technique than it is to be worrying about what specific oil you are practicing with.

 

Thanks for your reply! Good point about surface tension, should've thought about that! It's funny that you mention the specs because the only places I can find specs about Tillwich are on sites where they sell it, personally I find own their site completely useless when looking for specs whereas Moebius at least has an overview page where you can find some basic specs. The only places I've found stuff like oiling charts with Tillwich are on some forums. Thanks for confirming my thoughts, I'll wait to see if maybe other people can share their experiences but I'm pretty sure I'll end up ordering the Tillwich set I had put together.

Edit: decided to just go for it and ordered the 1-3, 3-5, B52 set!

 

Back in the old days, we essentially had two weights of oil for our cars...30W and 40W. The 40 was more viscous...we used it in the summer. 30 we used in the winter.
The introduction of multi-weight oils: formulated to maintain fairly constant properties summer and winter...and in fact at ambient temperatures seemed to be a little more viscous at some warmer temperatures than some cooler temperatures.

Viscosities at 20C does not tell the whole story.
941 and 9415 are greases...yet have excellent "sticky" qualities (they stay put) and incredible "slicky" properties...hence their ideal mission as escapement lubricants.

There is more to the chemistry and physics than viscosity.

I use 9 lubricants + epikote.
On most individual automatics I use 7 of them.
I worked under a CMW, who used "watch oil", "clock oil", "stem grease", "braking grease"...that was his full compliment. His work was acceptable...clean...lubricants in the right places...but not exceptional.

The subject of lubricants and lubrication has been thoroughly explored, celebrated, and obliterated elsewhere on f6.

Not the Holy Grail...but a good start: https://www.google.com/url?sa=t&rct...ractical_Lubrication_of_Clocks_and_Watches.pdf&usg=AOvVaw0Nlfmcsoljrth5lg8fHEYU
