actually 50/50 can have you overheating.

in wisconsin we have to change our mix. in summer we can be almt 100% water, but in winter its something like 66%/33%.

the best thing to do is get a hydrometer, its like $8 and then you know its right. you people are so concerned with following the manual, and to be frank it's not really based in the real world...its based in a world of 0 variables and perfection...its a midstream to cover hondas ass in respect of florida, california, and canada temperature extremes. you -should- be using a hydrometer.

just from scott's chart i know i would have to be nearly 60% antifreeze in the winter or i could lock up. and in the summer that same mix would see me popping my head.
