Default 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.

Drive to MI. I have a 30 lb. jug of R12. I'll get you charged up.

John D., did you do an ADD or complete change? Do you recall what you had to do for hose and fittings? I know my R12 stuff didn't match up to the can... which is still sitting on the bench. Not trying to steal this, but figured it'* something Red would want to know too. thanks

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?
