What's the difference between lithium grease and moly that makes you choose the later?
The MoS2.
Retinax AM (latterly called EPX2*) is actually a Lithium-soap thickened grease (nearly all commercial greases are), it's the addition of MoS2 solid lubricant which makes it better than lithium greases without EP additives.
* and they've renamed everything again. Of the current Shell range, I'd pick Gadus S2 V220AD as it has the MoS2 and it is Lithium/Calcium thickened, which is more water resistant than plain lithium. Buy online ~£6 for 400g.

I can't find the TDS for V220AD where it indicates it has an MoS2 content? Got a link for this @mdcc_tester ?
Other greases to consider for the lulz:
S3 V460D and V460XD has 5% MoS2 but is twice as thick at 40C at 460CSt, compared to V220AD at 220CSt.
Shell Aeroshell Grease 33MS seems to be interesting, with a very low viscosity of ~14CSt at 40C, 5% MoS2 content, and lithium fortified. There is a water separation stat available on the TDS of 33MS but I haven't checked it against the testing and methodology of V220/V460.
Edit: just realised I'm a muppet, 14CSt is very flowy at 40C - it's mainly used for low temperature/high altitude applications - think 0C to -40C and below where it starts to thicken.

Better how though? Is it slipperier? Does it wash out slower? Spread better? I dunno - what properties are good in a bike grease?
