Interesting ... How many timing chains have been replaced? Have you
measured the chain stretch?
Marshall said that the synthetic drastically reduced the rate of chain wear
and that it was measurable. You might be able to confirm or debunk that.

If memory serves me correctly, the term is “miscible”, and R134a is not with
mineral based oils.

You have ensure the oil is something that is compatible with the refrigerant.
Anything else is murder. (To the compressor.)

Well, I hate to even chime in here, but... I know some of you are purist, but
my 1983 300D with over 360,000 miles and still the same compressor from 20
years ago, has run R12, Freeze12, DuraCool, R134a, and something else. The oil
has been mixed. It will still cool if topped off and stop
Correct.

that’s still in the system, as well as why all the R12 leaked out. If it’s an
R12 system it’s got mineral based oil in it which does not dissolve in R134a,
meaning you might end up with a failed compressor down the road
Basically if the R12 has all leaked out, all you need to do is put R134
fittings on it and charge it. Nothing else is required.

Either FB makes people stupid or it attracts them. A “25 year mechanic” who has
half a brain would know better than that.
Do I understand that they were suggesting dumping R-134a in on top of R-12 in
the same system?

Well they were talking about recharging a R12 system. A “25 year mechanic “
says just buy the fill adapter and dump in 134. I say that won’t work then
others chime in it’ll be fine, I don’t know anything
