Hello,

first of all, I'd like to introduce myself. I am a student currently living in Australia and will go back to Europe later this week. At home, I do have an old Mercedes car with an ac that never worked. I'll overhaul the ac next winter to enjoy it in summer 2010. Here in Australia I learned that some people use mixtures of propane and isobutane in their AC as a replacement of R12. I know that there is no real chance to get these blends in Europe. But there is plenty of refrigartion quality R600a available. My question is: Can I use pure R600a instead of this blend? The AC is an expansion valve unit, just as an additional information if this matters.

Thanks,

Knusti
