Hello everyone, works (can’t – I can’t do anything, can’t – I didn’t ask “I would” – I ask exactly that) a propane/butan mixture (e.g. autogas, weeding gas …) a) as R1234yf – replacement gas, or can b) an existing R1234yf analge be refilled with it (“panned”? Background: This Thena here https://www.motor-talk.de/…/…eltemittel-zu-r134a-t6008957.html?… .Easyklima.at offers replacement fillings, but different for R134a and R1234yf. What is different? Most discussions always refer to R134a here. But I’m talking about R1234yf in this case. Does anyone have any experience with it? Thank you.
