You guys make that sound really scarry $$$ wise. I can see why dokhans want's a different (normal) type on there. What a strange setup.....

Btw, I know some will disagree, but I've converted at least 6 different (none MB) from R12 to 134. Two I flushed out the original oil first and added the "134 oil", the others I just added a bit of new oil to comp the losses. The first was probably 6 years ago, so far no problems. I looked at it like this: There's no way I'm changin all those seals n stuff, so this will either work, or it won't. As I suspected, the rumors about seals, oils and whatever else needed for the conversion was just a scam generated by those who sell the stuff.
