Hi dascru,
Finally someone on this forum older than me.
Here is what I found out about R-406a: DuPont doesn't recommend it because of its extreme fractionalization (or maybe because they didn't invent it). Even Autofrost does not recommend it in a system with PAG oil (see website http://www.autofrost.com/frmain.html ) The EPA says it can replace R-12.

Sadly Mayball, after his first post back in August he hasn't come back again :(

Oh well! Maybe he was looking for a different answer.
