But after reading this thread, I'm concerned about the viscosity of these fluids. the -40F rating for the Motul is 1750, and 1400 for the ATE 200. That's way over the ~700 of low viscosity fluids.
So, are there any high boiling point DOT4 fluids that are low viscosity? Looks like ATE SL.6 is a LV fluid, with better than OEM boiling temps. But it's a long way from the track oriented fluids. Anything better out there?
Or, does everyone just switch back to low viscosity fluids in the fall? (I live in Minnesota, so a -20F day is fairly normal. I'd like my ABS to work well in the snow/ice/cold.)
