Mid way through building XXX-CR - HELP!

[DomRC]

Am starting to build the diff, and noticed the instructions say some parts need grease and some parts need clear grease. Losi have only supplied a tube of "synthetic lubricant" with the kit... does this do the job for both normal and clear grease or do I need to get something else before carrying on?

Help please, I'm dying to get this finished!!!
