My condenser line got punctured between the dryer and the coils and all the freon and a lot of the oil sprayed out. I replaced it and I'm going to recharge it. It had R134 in it. Is it ok to just add Johnsons freeze 12 to it or should I go back with R134. Some oil is probably still in the system. How do I know how much oil I need to add. THANKS RAY M

I was told that freeze 12 has a flamable contenr in it and it's not the best thing to use. So I guess it's back to the 134. Does anyone know how much oil it would take after a situation like this. How would I know when refilling how much oil is enough. Is to much oil a problem. Thanks

Well, the problem is you really have no way of knowing how much oil to add without a complete flush. Since that really isn't practical under these circumstances, I would probably put in at least half of a full charge. Others may shed better light on this subject.
When I bought my old 80 wagon, the shady seller had it crammed full of oil. It foamed in the sight glass. It also worked unbelievable well. I would rather have a little too much than not enough.


Freeze12 is not flammable like the hydrocarbon products, it is merely a blend of R134a and R142b I believe. And I have it in the wagon, and it isn't quite as good as R12, and isn't that much different from R134a to be honest. Both are adequate up to about 95 degrees ambient.

Are you thinking I can just replace the lost 134 with Freeze12 without any problems. I have some. I also have some 134.

Nope, you cannot mix the two. Freeze12 is a specific blended amount of the two freon types.
If you had R134a, go back with R134a.

You should evacuate the system and replace the drier. Then use what you want.

If your state allows it and you want, you can replace the 134a with hydrocarbons. I would be quite tempted.

Thanks JIMMY L You have been very help full. RAY M
