Yes. Even stupid questions deserve to be answered. I know that lubricants are used for sex, but I doubt that this is why they were used here.
Machinery. Pistons don't slide, recoil-absorbers don't stand up, ball-bearings don't bear up, without lubricants.
Is it turning? It needs lubrication. Is it sliding? It needs lubrication. Is it absorbing shock? It usually needs lubrication.
It's that vital.
Thank you. See, this is why I am a total n00b.
Aviation used a lot of lubricants. Schmierstoff is the German word for it. They usually used the Shell products called the ASM-Serie (Aero-Shell-Mittel), with the commercial name Intava.
There were different type of aviation fuels and the matching lubricants.
Typ A 3 (80 octane)
Typ B 4 (87 octane)
Typ C 3 (100 octane)
The most common lubricant I see in technical sheets is the Rotring, or Intava 100. But there were also others, like:
Intava 60 (Weißring)
Intava 80 (Grauring)
Intava 100 (Rotring)
Intava 120 (Grünring)
Intava 140 (Blauring)
Also, they used Shell oils in aviation, like the Shell AB 11, and lubricant greases and pastes, like the VDM-Serie (42: Spezialfett, 43: graphite paste).
For example, the Fw-200 C-3 carried 8060l fuel, 570l lubricant oil and 27l oil when fully tanked. The Spanish gained some experience with crash-landed and formally serviced Condors, so they employed a few even after the war.
