Keep in mind that the snake oil refrigerants that are NOT flammable are BLENDS. When you have a leak, the components leak at different rates. To get the system charged correctly again, you have to empty (recover) the remaining refrigerant, evacuate and recharge from scratch.

Another serious downside to the use of this junk is that it is often put in a system without labeling or installing the correct fittings in spite of the fact that this is illegal. This results in the poor folks that are trying to make a living in the auto a/c business mistakenly recovering it into a tank of 134 or 12 resulting in the entire vessel being contaminated. A big problem for these hard working souls.

It really amazes me to see how often someone will spend $500 or $1,000 or more on compressors, condensors, evaporators and who knows what all and then scrimp to save $50 or less to use a junk refrigerant.

I personally find no reason to use any of this junk. I will only use 134 or 12.

Have a great day,
