Appearance ......................... Blue Density at 20°C ................... 1.07 g/cm³ Freezing Point ...................... -37°C/-34°F Flash Point ........................... None Boiling Point** .................... 129°C/265°F Water Content ..................... 50% pH-Value ............................. 7.7 **Using a 15 psi (103 kPa) pressure cap at sea level however I have seen references to -62F as well. interesting My thoughts: Almost all 50/50 ethylene glycol based antifreeze is good to -34F The -62f might be some sort of misprint based on a higher concentration of 60% or 65%

I agree with Rand. Very confusing literature out there. I think they meant to say "up to" -62F, if doctored up with concentrate. I've seen a forum thread that states the concentrate is available if one wants to go below the -34F rating of the 50/50 mix. Here's another link suggesting -34F at 50/50: http://suforester.com/products/696
