I work at an auto parts store and know that freeze 12 is junk. it is a mix of r12 by-products and r134a along with a few other chemicals. it works ok but no one will want to service it if they know it's in there. it has the habit of wearing seals and compressor bearings due to it's unpredictable chemical makeup. Darkstar <snip> I have also heard about Freeze 12, a drop in replacement for R-12. I think the system will run better on this stuff than R134A. <snip> Andy [Non-text portions of this message have been removed] To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
