Well admitedly I have been out of the garage world since 2010 except for working on my own vehicles. Then and before 2010 I was a lead diaognstic tech and I saw it ruin more engines, cause gasket issues, clog radiators and heater cores than I can count. I still will not use it after all I experienced. What we were made to use in the shop had no pellets in it and I know the Chevy garage here used the same stuff we did. Hope you dont take me wrong I am not arguing thats not my thing on forums. I am merely explaining where I'm coming from.
