I have a jug of R406a sitting in my garage. I have used it only once to charge my w108 and it worked well until it leaked.

Yep, oil circulation with your refrigerant is sort of important! There are MANY junk refrigerants that will make you cool, but not all of them will KEEP you cool for the long term.

Autofrost is a blend as well. Notice they did not test ester type oil with Freeze-12.

Oil circulation IN THE REFRIGERANT is PARTICULARLY important for those of us ( a lot of us ) that have the R4 Delco compressor because it does not have an oil sump like most later and earlier designs had... The old York did...and the newer swashplates do...but the R4 does not....

Yeah, the R-4 was another great GM design. The A-6 was a good compressor and also had an oil sump.

Tests like these cost SOMEONE some money. There are so many junk refrigerants out there, it would cost a fortune test them all.

Since some people have been serious and others sarcastic in this thread, what are the GOOD compressors, from among those described? I'm asking because I want to put some simple systems on Citroens and on a 1950s MB. The old big York was used because it was part of a "tack-on" system, but I have to think there are better ones out there that might just need fabrication of a bracket or two, in order to be installed. If this needs to be made another thread, I'll leave that up to the webmaster. I think it might be useful.

If the space you have to fill is made to accept an R4 already... you can get one which will be just fine as long as you are using the normal refrigerants.. R12 or R134a... and the proper oil to go with them... after a legit flush..
The way you do that is check with someone like Tray at Carlisle Auto Air in San Antonio concerning the serial or model number of the R4 you want to get... they are millions of them out there doing just fine with R134a... if you get the ones built for that.. Otherwise, any of the swashplate later compressors will do just fine as far as I know... they are smooth and have oil sumps... swashplate ones will look more like a starter... long and cylindrical compared to our R4 Delco... You could check the space you have to install it... and where your lines need to come in from and go to....and consult with Tray about the ones they get the least complaints about...

The York compressor soaks up a little extra power, but they are cheap and work quite well with R12. They don't convert well to 134 though. They just don't handle the added head pressure for very long.
For retrofit systems, the Sanden is the de facto standard. A variety of brackets are available and they are a very good compressor. Also, they are made in the USA. I've been in the plant in Sachse, Texas.
