The owner's manual says if your external temperatures are above -35*C or -30*F, you should use a 50/50 mix.
FYI, if you were to go to one extreme, use 100% water, not 100% antifreeze. Using concentrated antifreeze in place of a 50/50 mix will cause overheating issues... and is almost twice as expensive as it needs to be.
