For manuals of tamiya kits take a look at this: tamiya.com/english/rc/manuals.htm
The oil that comes with the M-06 Pro kit is the clear one with a viscosity of #900.
My clear oil dampers work great, too, but they're loosing oil.. I'm changing the o-rings now and see if it's better. If not, I'll go look for the tamiya M-TRFs. A friend of mine got them for his M-05 and they're doing great... no leaking at all.
