Develand,

Anti-freeze is exactly what it is. It doesn't freeze and it doesn't evaporate so its basically water that anti freezes and doesn't evaporate.

So, the difference between green and dex is that if ur next door neighbor's dog licks the dex it won't die. And dex smells real rotten when its old.

U shouldn't see a temp difference unless u too didn't bleed the air.
