Does anyone use Purple Ice (by Royal Purple), or recommend it? It's an additive for your coolant that makes your engine run a bit cooler. My neighbor recently showed me it and swears by it, saying the coolant's about 15 degrees cooler. I figure on a high performance car like this, we can use cooler coolant temps.

Hmm........snake oil

 

If it's anything like Redline watter wetter, then it's not snake oil. It works.

 

What's snake oil?

 

Royal Purple makes quality products. Like above, if it's like Redline Water wetter (I've used it) then it works. It's useful if need only a few degrees difference if you're on the edge of your cooling system and cannot or will not change parts.
