    Need some backup here. I was talking to a friend of mine last night and he was saying how he ran 100% antifreeze in his cars with no water. I know this is wrong and he is the only person I've known who has done this, but I didn't have much ammunition to back up my claim that I was right. Help me out. I run 50/50 mix in the winter and usually 70water/30antifreeze in the summer. Does it just not cool as efficiently when its so concentrated? TIA

    That synthetic stuff sounds cool, but he was just talking about regular old Prestone.

    For ammo, just grab a bottle of antifreeze - it says right on there the proper mixture.

    Check out one of the newer (Peterson?) Four wheel mags. They did a test, straight water cooled better than an antifreeze mix. Antifreeze helps fight corrosion and freezing, thats it. The less you can run of antifreeze, the cooler it will run. Water wetter, some anti corrosion additive (if necessary with water wetter) and plain water (or distilled if you are anal, no offense : ) will cool better than antifreeze.

    Pressure in the radiator is what increases the boiling point, not the antifreeze. Boiling point raises some 40 degrees with 16 PSI, about 4 degrees with antifreeze.

    Good call. I just looked at the back of my Prestone jug and it talks about the 50/50 and 70/30 antifreeze/water mixes. Absolutly nothing about 100%.
