I have a bottle of Prestone Premixed LongLife Antifreeze/Coolant. It says 'all makes models add to ANY colour antifreeze'. It's most definitely green in colour. On the back it says it contains water, ethylene glycol, diethylene glycol, sodium 2-ethyl hexanoate and sodium neodeocanoate. Even though this stuff is green, is it a Dex-Cool type coolant?
