Just for info:
Krytox is a huge range of oils and greases. Most are only available in large quantities and massive prices!
What most of us are referring to is GPL105 which is an oil of medium viscosity. It happens to be the stuff recommended and branded by Volkswagen to lubricate the special rubber seals on the EOS. So it is available in a small dropper bottle. The whole range is something like GPL101 - GPL109; getting increasingly viscous.
They then pack it full of extra fine PTFE to make the greases. GPL201 - GPL209 Again, the only one available in the small tubes is the GPL205 mid viscousity one.
They do have a range with molybdenum disulfide mixed in for high load slow moving application which is the GPL21x range. OK if you want a tube costing £1000 !!!
And many more specialised ones.
If you are as anal as me then look them up on the Dupont website.
