Motul 600 is good for the budget but less heat tolerance than the Project Mu or SRF and it needs more frequent flushing.
Looks like Mu dry is 335 and wet is 221. http://project-mu.co.jp/en/products/other_fluid.html
Castrol SRF dry is 310 and wet is 270. http://www.castrol.com/liveassets/bp...s/SRF_B768.pdf
It's the wet boiling point that really matters since that's what will affect your pedal feel. Mu is a little cheaper.
It's too bad LeMans_Blue isn't here anymore. He'd give a NICE summary about brake fluid.
