eye opening experience

I purchased one of the Prestone "testers" and used it on the E320. The percentage was around 55% MB coolant/45% water. I drained some out and got the mix a 40% coolant/60% water. Man, what a difference in running temperature. I would have never imagined that it made as much difference as it did.
Thanks for putting me on that tester.
