Hi all: For several years now, I have ben using FRIGC FR-12 in my 300F and '76 NYer. It is a blend of 65% R134a and other gases. It is a direct replacement for R-12. All that is necessary is to evacualte the system, add a couple of ounces of specified oil and charge the system. It takes only about 80% of the R-12 requirement and operates at lower pressures. The cooling curve is exactly the same as for R-12. I purchased a 30# canister years ago and from the limited number of times that I need to top of the cars, it will last for many years. Since I have not been in the market for this product for some time, I have no idea of who sells it throughout the USA. I found a company on the internet called Refimax who has some information on it. I also have an older web site that has a wealth of information but each time I attempt to put the URL in this e-mail it become highlighted in blue and I know the list server will kick it out. If someone can tell me how to put it in an e-mail so it will not be kicked ut, please advise and I will broadcast it for the members.
