BTW, R-12 is in no way illegal to use. However, it is illegal to knowingly release it to the atmosphere, to import it into the US and to manufacture it in the US.

Also, the market is flooded with R-12 replacement refrigerants, and they all claim to be the next big thing. Many people will attest that they work and they cool. However, Sanden (the manufacturer of the stock Delorean AC compressor) do not recommend any other replacement refrigerant than R134a and PAG oil.
Someone in a previous post mentioned a company that recommended charging liquid refrigerant under atmospheric conditions (i.e. not under vacuum). Highly questionable. The deeper the vacuum the better. And charging liquid on the low (compressor inlet) side is typically not recommended. It can be done as long as you go slowly without causing a hydraulic lock ("slug") in the compressor.
Came here to say that as well.

Do yourself a favor and just stick with either R12 or R134a. Don't play around with these Hydrocarbon blends. It's not that much different than just pumping butane or propane into your A/C system.

Alkanes, or HC-based refrigerants are NOT approved for use in A/C systems that were not designed specifically for them. As an aside, I don't understand why we'll swap out NCTs, door seals, fuel lines, and coolant hoses, but insist upon trying to keep the entire A/C system in place to reuse it.
R12 or R134a are your best choices when it comes to your car. Stock runs with R12, but it's really only a minor cost to upgrade to R134a, and it can give you pretty much the same performance with a much cheaper maintenance cost in the long run given that R12 is about 5x the price. And if you need to replace the compressor anyways, then you can get a much better compressor designed for R134a too. Running these HC gases are dangerous as all hell.

My two cents: Don't forget in your electrical troubleshooting to make sure that your diodes have not gone bad or have a flaky connection.

Yup. The certificate is $20 and you can test online to get it.

Do you guys know if the red trek 12a works with the mineral oil currently in the system? Also, is there any way to check on the level of the mineral oil in there?
You can't buy happiness, but you can buy a DeLorean and that's sort of the same thing....
