Warning, don't use this product!

I gave Lucas Super Coolant a try in my Honda race engine and it quickly became clear to me that there is a huge problem with this product. It became a solvent on my aluminum radiator and destroyed two of them back to back before I figured out that the Lucas additive was the catalyst for the destruction of two radiators back to back. I changed back to Red Line Water Wetter and have had not additional problems since then. The Lucas additive was the only change I made. Here is a link to my pictures and other info here: [...] Update, Amazon doesn't permit hot links. You can find full write up I refer to if you Google this term: "hondatech.com: lucas super coolant" and you will find my full write up w/pictures.

Seems to make my engine run cooler. Temp gauge is a little lower. I've burnt two head gaskets in two years we'll see if it helps in the long run.
