What I meant to say is there is no commercial refrigerant that's
suitable for automotive a/c system.

able to run any in a car but commercial applications I know
of besides R134a.
R744
R290
HFO
R410A
R404A
R407A
R11
R22
R114
and of course the ammonia derivatives.
I was a data center IT guy so keeping crap cool
was a big thing. Not sure which of these get used where or
how, but they are out there. Some of our centrifugal
compressors had 6ft diameter impellers and ran on direct
4160volt feeds from the power company. I think that would
be considered commercial.

IMO your car guy does not know what he's talking
about. There is no such thing as "commercial"
refrigerant so he's probably referring to R134a.
Here's a good read on converting from R12 to R134a -

Erik's analogy of the 512BB air

A car guy told me recently he uses
commercial A/C refrigerant in his truck and
the cold air it produces is insane. I asked
him which one he uses and hasn't gotten back
to me.
Is this something anyone would consider
on the older cars? It's better than using
R12.
Nobody should have to suffer from subpar
A/C in a 30 year old car, and that statement
alone should stand up in the court of law.
