>>100% glycol -14
80% glycol/water -38
60% glycol/water -50 See where its leading ? 0% glycol/water i.e. water
-60 at least<<
Nope. dig out your physical chemistry notes. It starts to rise again at 50%
Most of us seem to be running at 75% glycol or thereabouts. The compromise is
boiling point related. Glycol boils at around 170 deg, which is why Rotax hint
at its peferability. Something to do with suspect hot spots in the heads.
Trouble is conductivity and flow rate tend to be worse.
Anything to add Duncan?
