For those who are picky about their fluids, what fluid do you recommend?
I plan to perform this DIY with my Motive 'Black' European bleeder.

While i obviously do not race my CTT, i still want a high performance fluid.
Only other prerequisite is to have something highly compatible with winter temps down to -30 degrees.
Yes, i live in Minnesota....the new antarctica.

The fluids that have caught my eye:

1) Endless RF 650
2) Castrol SRF
3) Motul (not sure which version)
4) ATE Gold Type 200

The best performer that is good down to -40 is Endless RF 650.
However, its also the most expensive.
Best price i've found is $45 shipped for .5 liters.
The procedure takes a full 1 liters from what i've read.

Appreciate any advice. Thanks!

I did a quick search and found RBF 600 and RBF 660?
