well, since we are all throwing stuff out here, how about the stuff that says it meets gm 1825m/1899m on the back of it, I work for a Detroit diesel dealer and can buy it at cost, purple concentrated power cool with sca's for Detroit diesel's but it has these 2 gm ratings on the back. I have a 97 vortec 5.7 I just built and trying to save a few bucks where I can, I assume (that gets me in trouble sometimes) since it meets these gm specs, I should be able to run it. I tried looking up these specs but couldn't come up with a solid answer. I have ran green in just about everything with no problems, I have also ran CAT ext life red with no problems, but I'm not accessible to cat coolant for cheap anymore.
