ok ive been back and forth with this one and im trying to make a choice, ive read some of the threads argueing it back and forth. i know the green stuff is bad dont use it, it rotts aluminum. i was planning on doing a good flush and running dexcool again,but i keep having people tell me not to cause it just sucks and people have seen it gunk up and block passages and **** like that. now i hear people have luck with it also, what should i use, my only other thought was that yellow stuff thats suposed to to work with everything, how is that stuff any bad thoughts or expeiriances with it in our LS1's or is it the only other good alternitive to dex with no ill side effects like the green stuff?
