    Google only shows it has oil, stop leak and seal conditioner in it.

    It's the same (NEW STYLE) refrigerant with a small amount of oil and sealant added. I've used it in several OT cars and yes it works well. The sealant will deal with the tiny issues that develope where O-rings create seals. O-rings tend to 'dry out' and WILL leak over time, this new sealant is supposed to prevent has worked for me on a couple of different systems. FYI: I have been in the A/C business for 36 years.

    Maybe I'm asking about something different. The stuff I meant to ask about is like R134A super cool, or something along those lines. Which is marketed to make the system produce colder AC.

    What he said. It won't make your system "colder", unless the additives violate the laws of thermodynamics :)

    All it is, is lubricants so your system will work as designed like when it was new. When you overhaul an AC system, make sure you have the right amount and type of oil, and make sure to run it say once a week for a little bit in the off seasons, to circulate the oil and lube the seals/O-rings. This "cold-air" additive crap is snake-oil.

    The real secret to make it work good is to get maximum air flow across the condenser.

    Not too long ago I installed a VA Gen lV system and charged it with 134A. No complaints on cooling.

    If you really want it to perform well. pull a good vacuum. 50 microns is good and some where in that area is what you want. A poor vacuum means air & moisture is still in the system, and air does nothing, just rides along and takes up space, and raises the head pressure. Water freezes and messes up the oil and is corrosive to the internals and that is NOT what you want. Iceman
