Thanks! Well if I have problems with it I'll replace it this winter.

Oh OK. I had my original condenser but it was too beat up, so I found another one and bought it, but then when I removed my ducting I discovered the stock condenser was still too wide for where I was mounting it, so I opted for the universal one. Why are you getting a larger condenser for R134a? I'm planning on using the same refrigerant but my condenser is smaller than the stock one.

R134a is less efficient than R12, and therefore needs a larger condenser to achieve the same ⌂T. IE the conditioned air won't be as cold.

Dammit. lol Well maybe I'll keep an eye out for a more efficient refrigerant, because I really don't feel like reworking my whole system to fit a larger condenser. Or I'll just try R134a first. It's not like it gets SUPER hot here anyway.

Lots of refrigerants are hydrocarbon based, that's nothing new. R-134a is tetraflouroethane, and R-12 is Dichlorodiflouromethane for example.

Definitely give it a shot. I would also not hesitate to run ES-12 if 134a doesn't work. ES-12 should be similar to R-12 efficiency wise.

DustOff FTW! Its has the same cooling characteristics as R12 and is loads
cheaper. Also will work well with existing condenser.

I fixed the leak in my system this summer and charged it with the duster stuff. 2 cans for $10, it's cheap enough that I would just try it with this stuff first and see how it works in your car.

Well I was planning on trying DustOff or something but then I was reading about it being flammable and all that. So I started looking at more conventional stuff.
