Not a good mixture in my opinion. G-5 is a "HOAT" and not really compatible (kinda sorta) with the "OAT" water wetter. FYI Purple Ice and Super Coolant are both HOAT types...... BUT none of the additives really do anything when added on top of 50/50 antifreeze (the way most people use them....incorrectly)
