Anyone used FREEZE 12 instead of R12?
AC system has a slow leak according to it's old owner that I work with and trust. She advised that she used to top it off with R12 at the beginning of the summer and it would last for 6 months. Has anyone here used Freeze 12, what is the disadvantage of doing so, supposed to be compatible with R12 systems without requiring any type of conversion.
Seems like it might be cheaper and easier for me, rather than screwing around with R12. Certainly don't want to take it in for AC service, trying to do everything on this truck my self if I can.

allthough many have reported good luck with converting i have personally talked to quite a few people who have said that even though it does cool, and that's better than nothing, it was colder with the r-12. so instead of converting just use the freeze 12 it is a direct replacement and can be put right in with the original remnants of r12 and will cool better than the 134.

I was curiosu about this whole subject.
Found this which I presume (by the .gov site) is sort of reliable info

The guy at the counter here in Petersburg said he had the little can's of R12 locked up behind the counter cause people steal em blind. Asked how much he said 38/can. The license issue never came up. Did't see em so dont know if he was blowin smoke or not.

Aren't you supposed to replace the compressor when switching to R134a? As it needs to be compressed more than R12 hence burning out the stock compressor in no time?

Not that I'm aware of. They've been selling these kits at Walmart for a good couple years now. I've never personally put one in, but they seem totally basic.

To convert to R134, You have to replace the drier, perhaps the expansion valve (it's recommended to do so anyway), flush the system, replace the oil in the compressor with a type that's compatible with R134, replace any hoses with barrier-type hoses, and evacuate/recharge the gas from there. Not too hard to do, but there's a little more to the process than what they tell you at WalMart.
R134 doesn't cool as well as R12 did and it's harder on the compressor because it requires higher head pressures.
The oil issue is the biggest problem. R12 systems used mineral oil. R134 doesn't like it. The result is a dead compressor from poor lubrication.
