Thanks for all the replies. My mixture originally was 50/50 but I was down about 2 qts. so I added 12oz Water Wetter (no Water Wetter in coolant previously) and topped off with distilled water to fill the system. My ratio now is 45 glycol/55 water along with the Water Wetter.

My temp gauge reads in Celsius and before typically ran in the 85-90 range. Now after the Water Wetter and additional coolant it runs in the 80-85 range on an 80 deg. F day when running moderately hard. After coverting to Fahrenheit this works out to about a 10 degree improvement. Not bad.
