We talked about this stuff a while back and none of us weren't sure if it was worth the expense or not. Well a online magazine called JPFreek (http://jpfreek.com/past-issues/) is using the stuff in a LS V-8 they installed into an older CJ. The articles start in the Winter/Spring 2017 issue. Next in the Summer 2017 and the latest is the Fall 2017 issue. They are saying they have had good results with it and like the stuff. https://www.evanscoolant.com/ or you can buy it from Summit Racing also. https://www.summitracing.com/search/...0Systems%20Inc.
