Coolant mixture for hot weather?

[TenaciousB]

Hey guys, spring/summer will be here soon. I was thinking of flushing out my engine coolant. It gets pretty hot and humid in Indiana during the summer, and I was thinking about changing the mixture from the "golden rule" 50/50 mix.
I was wondering if anyone has done this and seen a significant drop in temperature. From what I could find it sounds like an 80/20 mixture might yield a 10-15 degree drop in engine temp. The only thing that suck is I will have to do it all over again once it turns cold.

Do what I do... Take two fukitols and use Engine Ice. It's pricey, but a laser thermometer showed a 10degree difference of temps at idle in the dead of FL's summer.

Water does cool better. Do 35-40% coolant, 60-65% water.

http://www.engineice.cc/ Just use it alone. It has ionized water in it already.

I would suggest a 6040 mix with Watter Wetter. IT can be found at Pep boys Advance auto ect ect.

It's a lot cheaper than my stuff too. But works well
