Ready to do another coolant flush and was wondering if I can keep this mix during the winter in NorCal (Bay Area). Sometimes it gets down to 30s, but inside garage should still be in the 40s.

Or should I just do a 30/70 coolant / water+2 bottles MoCool mix? Wonder how much difference it is to 100% distilled + 2 bottles MoCool?
Great question. I want to know as well. Why 2 bottles though?

Is that Coolant/Water or Water/Coolant?

Your typically in the 2-3-4 upshift/downshift, and the clutch packs will get very hot when you do this. This heat is transfered to the trans fluid, and then to the coolant. I leave the tranny in DS mode, and the computer doesn't allow radical downshifts/upshifts, while staying fairly aggressive, and keeps coolant temps low. I don't know how much heat traction control is adding, but remember, we have an open differential. Traction control is the only thing stopping one wheel from spinning faster than the other. Turn off, at your own risk! The car's handling is pretty on point, but TC off in the hands of a novice is dangerous.
Perhaps for those, like me, with a LSD, it does.
