Is FR12 freon the same as R12? Can you mix them or are they interchangable? I was at Super Chevy in Indy and saw a guy selling it for $15.00 a can. Was that legal or a good deal?

FR12 or Freeze 12 is a drop in, EPA approved refrigerant that you can use with R12. Yes, you can use it legally. I wouldn't buy it from some unknown person, get it at a reputable parts store. Narti

to add to Narti's post; yes it will contaminate your system, it is probably a mix of r-12, propane and/or butane and I wouldn't want that stuff in my car.

The bitterness of poor quality remains long after the sweetness of the low price is forgotten.

FR-12 is manufactured by a subsidiary of Intermagnetics General Corp and is unconditionally approved by the EPA as a substitute for R-12. It's formal name is Frigc. Pennzoil was the distributor for FR-12 for a while. I used to own stock in IGC so I was very interested in the performance, approvals, etc. It was used at some U.S. Air Force bases in support vehicles with good results as far as I know. I saw some auto A.C. system vent air temps and the FR-12 temps were about the same as R-12. It looks like a good, safe replacement.

Is FR-12 also called "312"? A couple of guys told me about it and said they used it interchangeably with R-12.Also,what was the name of the refrigerant that was combustible? I think I'd want to avoid using that one.

I was at Indy also and set up in the swap area. I stopped at the vendor selling the FR12 and looked over his offerings. I picked up a can and read the specs on the chemical composition of FR12. It stated that it contained 2% Butane. I have heard reports about refrigerants containing a percentage of butane or propane gas which might create a hazard due to butane/propane content. I don't know if all refrigerants contain a flammable liquid/gas but would like to know more on the topic.
I have visited with one of the principle people at one of the major aftermarket air conditioning companies about FR12. He has used it in a "driver" for test purposes. He told me that he did everything wrong that he could just to test the product. He never evacuated the system or replaced any components......he just added FR12 to the R12 in the system. The car has been in use for several years with satisfactory results. I will say this.......He DID NOT RECOMMEND doing this. Any use of FR12 should be done using correct procedures by evacuating the system first. I am not pro or con, just giving information furnished me. Be your own judge on what refrigerant to use.
