I added this to the coolant of my 2007 Saturn Ion Redline Edition. I wanted the engine to warm up faster. I don't think the engine in my car actually circulates coolant until it reaches operating temperature anyway.

Regardless, my normal operating temperature is maybe slightly higher than it used to be, but it's hard to tell. I do have a digital readout of engine coolant temperature using a bluetooth OBDII adapter and the Torque app. I added this at the end of the summer, and it seems like maybe my coolant temp is 5-10 degrees warmer than it would be otherwise.

I will try out DEI's cooling products and review those. I'm especially interested in the intercooler stuff because my car is intercooled and supercharged.
