AC R-134a replacement

I used it on an old beer kegerator. It already had a partial charge, so I didn't vacuum it and it worked fine for years after that.

An old refrigerator would have been (partially) charged with… R12?

Correct.

I've used that product before. It works. It's propane and isobutane, IIRC.

It's more flammable than other refrigerants so you might want to weigh that in your decision.

I have used Duracool before that is basically the same stuff. That being said I like R152a better. Its not nearly as flammeable and the pressures run lower on R152a.

Ditto on sucking it down 1st, and leave it under full vacuum overnight, if you have the time!

Which oil is appropriate for these "mixture" refrigerants / blend refrigerants? Mineral or PAG? I've read in the past but don't remember.

I thought most of them were designed as R12 retrofits, so my knee-jerk is they're miscible with mineral oil. Are they miscible with PAG?

I've not been a proponent of any blend refrigerants in an automotive situation b/c of fractionation of the blend's components as the system leaks over time. Tightly closed systems, like those in refrigerators, seem to be the better use case.

Or Ester oil.

Robot or human?

Good question have a look...

I was told it was a Valeo DKS compressor.

Can't find any pics of a Valeo that look like mine.

Here's a pic of mine...

Looks like a Sanden to me. Maybe a 508.
