ac conervtsion to r134a

[netcsk]

according to BMW, r134a conversion blows just as cold as original r12. they have temperatures for different weather conditions comparing the two, and the difference is never more than 1-2 degrees.

all those r12 replacements are gimmicky. they are often just r134a with some specific lubricants and oils that protect r12 seals.

So you've used them all? Please tell me you've at least converted your system.
Freeze12 is a blend, but hardly straight R134a. They are designed to push the operating point down to the pressure where R12 is most efficient. It also works a shit ton better in these cars than R134a. I've converted with both, and unfortunately I didn't "convert" mine to run with Freeze12.

I hate R134a, my car came to me converted. It sucks. But that's just me, but it leaks like swiss cheese. Hopefully someone else has a better experience.

I'd rather have r12. But then again, I have the license to buy it.
