diff oils/lube/grease?

[maxxdude1234]

hi,
I just brought a set of FLM diffs from here, but I have absolutely no idea what they should be filled with, or what lubricant to use on the ring and pinion gears.

Could you please reccomend which oils/lube/grease I should use from THIS website: http://www.modelsport.co.uk/?CallFun...egoryID=604010 (I live in the UK, so has to be a UK website)

The hpi heavy weight diff grease at the bottom looks quite good, but can i fill the diff cups with this (pic here: http://www2.towerhobbies.com/cgi-bin...?&I=LXDHK6&P=7 )

Thanks for your help :)
