Freeze 12 - R12 substitute?
Anyone here used Freeze 12? I have been reading up on it and I have not seen anything negative yet...
My 93 SSEi is low and R12 is of course a bit hard to come by.

Didn't gm make the switch to r-134a in '93? Or was it just Ford?
We had the system on the '90 sse switched over to the freeze 12. It didnt quite get as cold as it did before, but still got the job done.

I've run it for 2 years now with no problems. The negative, or so i've read, is that it is a blend of r134a and r22. The r22 carries the oil, and it is a smaller molecule so if you have a leak, the r22 leaks out more quickly, leaving nothing to carry the oil. I've only read this one place, so it may be false.

Interesting - thanks...
My 93 has R12 and my 94 has 134a. So somewhere in the middle they made the change.
You know what really stinks - back in the mid 80'* I worked in an auto parts store. Any damaged cans of R12 (and a few that weren't), we would take outside and throw them against the side of the building and watch them explode. And we would also duct tape a can to the small plastic car that was our car-cover demo. Then poke the end of the can with a screwdriver and watch the car shoot across the floor. It was 99 cents a can back then. Wow, we were stupid.

The conversion to 134a is still an option. But the Freeze 12 (assuming no negative effects) looks like the most bang for the buck... That is why I figured I should see what people here have to say before I jump into it.
I converted a Chrysler minivan to 134a, and although it worked fine, I sold the vehicle after 1 summer, so I did not get any long-term experience.
(jr's3800) Could you go into some detail as to your conversion experience / recommendations?

No real recommendations..
On my 91 Bonneville LE I used the Retrofit kit in 2000... I added the R134a and the Ester oil which is compatible with the R12 Oil... I then charged the system to 85% capacity with 134a... With 134a you use a bit less as compared to the R12, I think thats due to the added oil..
My 91 After 8 years still cools and does it pretty well for a 17 year old compressor slowly working to its deathbed.. When I first charged the system with R134a it actually cooled really well sitting still on a 90F summer day.... It doesn't work as good as it used to..
I think the right way would at the very least would be to replace the Orifice Filter( Inline ) and the Receiver / Drier as well as the system O rings as the system would be apart.... From there being that the system has been opened it would be advisable to pump the system down and then recharge with 134a..
Too bad I have no experience with the Freeze 12 tho... wish I could be of more help there..
