Buried deep within the factory repair manual it is stated that you can run up to 70% water and 30% anti-freeze assuming you will never see freezing temps.
Since water has a higher thermal capacity than ''anti-freeze'', this should help transfer heat away from the cylinder more efficiently.
I have been using this 70/30 mix (using de-ionized water) and am curious what you guys think?
