Anyone here used Freeze 12 Freon?

[speeder]

In an older vehicle not converted from R12 system? I’ve always had decent luck just converting everything to R134 but I have one that still has the old fittings, so just curious. Thanks

I haven't used it myself but I know some shops here will not touch a system with it in.

I think I still have a virgin tank of R-12 kicking around somewhere.

Doesn't work. If you need R 12 go to a few garage sales they always have a few crusty cans that can be had for $5

I used some stuff that was isobutane/propane (I sure hope that is correct !!!) mix a long while back on some cars I no longer have. A mechanic turned me on to it. I was highly hesitant as this is a flammable product. I did a ton of research and made a leap of faith.

I bought it twice. First time was easy. Second I had to get it from Canada.

Safe? I can’t make any determination other than I didn’t blow up on me.

Effective? Yes. Cooled very well. Could not detect a difference from R12.

My opinion. Just another point of reference.

How long a drive to Tijuana

Yes. I use it all the time. Canadian product because US regulations.

This product is the same as the R-290/R-600a blends. Better for the environment. No more dangerous than a gas stove and this blend is used in a lot of new appliances.

CfC’s are such a bs market.

It sounds familiar, but it’s been years. IIRC, it worked well.

That’s what I did too, bought two cans from a guy off of Craigslist that I met in the Lowe’s parking lot.

I haven't seen a garage sale since sometime in the last century. There is always someone selling cans of R12 on craigslist here but for $40-50 a piece.

I recall doing this research years ago before conducting my R12 drug deal in the parking lot, and reading mixed reviews on Freeze12. Some people had good luck, some people had really bad luck. I think at the time it was my SC and I didn’t want to risk it.

I just saw a 30 pound tank of Dupont Freon 12 for $2,600. (I don't think it's been manufactured since the early 90's?) It's not illegal to have it. You just can't make it and you can't use it without an EPA 609 certificate (self study/online test/couple hundred $$). Just do the Lowes parking lot if a can is needed here or there.

FWIW

CFC-12 has a life of 102 years

If you pick up a rusty but full R12 can from 1972 is it already half way depleted? I don't know if the degredation occurs within the can or if free floating in the atmosphere.
