Another reason to NOT use straight antifreeze, it will actually freeze in cold temperatures. The automobile and antifreeze manufacturers know what they are doing on this one. If you want to limit the corrosion mix your antifreeze with distilled water, but add water, do not use it straight.

Jim:
Perhaps I mis-understood, but if by using "prestone straight up", you mean
you didn't mix it 50-50 with water, then you did a bad thing.  Antifreeze is
designed to be mixed equally with water for maximum temperature protection.
And why do you believe that a "local guru who has 50+ years of air cooled
experience" can competently advise you about your water-cooled engine's
needs (even if it's based on an air-cooled) ?
