Any info/advice will be appreciated

It's a blend and is not pure like R12 or R134. It's basically freeze 12 that has been tweaked so that 1% of the R134a is removed, 1% of the R142 is removed and an extra 2% oil added. You can use a blend but you can do better going with the more common R134.

Just stick with R12 or R134a... Problem is most A/C shops these days test the freon before evacuating, as they don't want to contaminate their entire batch.

If you've got weird stuff in there.. they won't touch it.. so if you ever need professional A/C service in the future, forget it.

There are also some legality issues in some states and the EPA.

I hear that 10 gallons of water and this little blue super energy pill (the oil companies are supressing it) will give you 100mpg.
wanna try it on your truck?

Stick with what works.
