Been thinking about using royal purple ice in my 2000 TL and just wondering if anybody has had any experience using this product.

I just finished changing the antifreeze and summer gets pretty hot here so I'm wondering if royal purple ice will help the cooling system run more reliably and efficiently.

So has anybody used this stuff before? Does it actually work or has anybody experienced any problems with it or should I just leave the coolant alone?

 

Go for it. Probably won't do anything, but it won't hurt anything. From what I understand, it can help in hotter temps but doesn't provide freeze protection.

I live in AZ, and the chance of coolant freezing is 0% year round, so let me know how it performs.
