SHELL GADUS S2 V220 00 is what Florain uses too.
Others have used ALPINE Fließfett DIN51502 GP00/000 K-30 (I have have a syringe of it too, but did not use it yet, but it seems to work well for others):

Anonther Greas which is pretty much the same (according to datasheet) is Castrol OLIT 00 (http://unicyclist.com/forums/showthread.php?p=1668675#post1668675) but none of us tested it yet.
Years ago, one bought a bucket SHELL GADUS S2 V220 00(maybe 0,5kg) from florian and sold it to others in syringes.
Ulkicycling (near Hamburg) has the 800g ALPINE Fließfett DIN51502 GP00/000 K-30 and can probably sell and send you some syringes of it.
