Coolant question

While i was getting a battery terminal for a Toyota, i noticed Prestone made a new coolant called Prestone Heavy Duty with Penray Technology in a black bottle and the stuff is purple in color. The bottle says its for both gas and diesel engines, it is precharged with SCA, and it also boasts a claim to be phosphate free and low silicate. Can this be a viable alternative to OEM coolant?
