Igor-

Welcome back.  I use Evans in my race bike but I had them make up a
less viscous concoction.  They now call it Ducati racing coolant.  It
works great but is only good down to -20 F.  So if you want max
protection at the track perhaps this would work.  When you can use
Evans I believe it is the best protection you can get.

Again- glad to see you back on the list
