mrfixiter Posted September 12, 2012 Share Posted September 12, 2012 Has anyone used Enviro-Safe r134a refrigerant? I found a long list of reasons to use it such as cost and compatibility, and a couple of exceptional reasons not to use it. Mainly, it appears to have the same chemical makeup as propane which is probably something you don't want to have in your engine compartment should a leak develop. It's hard to find a review from someone that doesn't represent or sell the product. Thanks for your reply. Link to comment Share on other sites More sharing options...
presslab Posted September 12, 2012 Share Posted September 12, 2012 Yes, I use the "Industrial ES-12a" in both my vehicles that originally had R12. It works great. Nothing to complain about, been running it a few years now. Indeed it is a mix of propane and butane. Link to comment Share on other sites More sharing options...
mrfixiter Posted September 12, 2012 Author Share Posted September 12, 2012 I should have mentioned it's for my 2001 Forester. From my understanding of its usage, it can be added to whatever existing R134a that still remains in the system. Thanks for your reply. Link to comment Share on other sites More sharing options...
danbennett2u Posted September 13, 2012 Share Posted September 13, 2012 I really doubt that the efficiency savings is noticeable. I personally would just stick with regular R134a refrigerant since that is what your system is designed for. Link to comment Share on other sites More sharing options...

If designed for R12, use the ES-12a. The reason EnviroSafe calls it R134a "replacement" is to skirt the laws regarding R12 retrofitting. Link to comment Share on other sites More sharing options...
avk Posted September 13, 2012 Share Posted September 13, 2012 A while ago, there was a house explosion in NJ caused by a newer environmentally safe refrigerator operating on isobutane. Maybe it's best to use flammable refrigerants only in unattended industrial equipment, something they were invented for. Link to comment Share on other sites More sharing options...

Maybe it's best to use flammable refrigerants only in unattended industrial equipment, something they were invented for. I think you answered my question with that story. I'll stick with the standard R134a formula. Thanks for your reply. Link to comment Share on other sites More sharing options...
