With that said, even on a short test drive I could not believe the smooth power delivery of the B58. Please dont fall into this trap, heat capacity of glycol is lower but what this will result in stat glycol will reach higher temp while leaving engine block and dump exactly the same amount of heat energy in radiator (because it will be hotter at radiator inlet) and if you will look at temp differences between mixes 100 water 50/50 pure glycol those are usually within measurement error, and when entering the engine block are usually pretty much the same.
