They have a new formula that is the race blend ... lower viscosity.

I run Engine Ice, easy to find, runs cooler than the old Evans, don't know about this new formula. Might try it sometime.

 

How do you know it runs cooler than the Evans?

 

Most Cannondale owners that have used the Engine Ice have reported that their fan runs much less.

When switching to the Evans from stock, most owners have reported that their fan ran more often and for longer durations.

Water is in fact the best coolant from a heat dissipation standpoint. Water Wetter as an additive has proven successful for many Cannondale owners as well, though it will have a bad effect with the magnesium valve cover. If that is taken care of you can run whatever coolant you want to.

The Evans is thick like maple syrup, hence why I suggest the newer, lower viscosity formula. Evans won't boil over but I'm scared of that. At some point I would want it to, before something else took a dump. A racer might want to keep going but I'll save the $ and boil over, no repairs to do.

It running cooler is based on the observations of many Cannondale owners, take it for what it's worth.
