I already bought one can of Emzone 12A can of refrigerant, It says it has UV dye & it is equivalent to 15oz of R134a. REDtek is 18oz equivalent. I need 32oz/2lb of refrigerant in my system. It's okay to mix 12A refrigerant brands?

You state 12A refrigerant in your title and mention 134a refrigerant in your post. Are you wanting to mix 12 and 134? No, will not mix. If you are wanting to mix different brand names of 134a refrigerants you can do that.

These trucks were never designed around R12a. It uses 134a.

R-134A refrigerant "brands" by two different manufacturers, when mixed, still results in R-134A being added totaling 15oz + 18oz = 33oz total. The dye is probably an additional 3oz and does take up space. Therefore you would roughly have 36oz when you empty both cans. Keep in mind the dye will somewhat lower efficiency, but not by much that you'll notice if a full charge is 36oz. The most important part of charging your apparent "open to the atmosphere" system is a good vacuum with moisture levels on your micron gage below 500 microns before adding the refrigerant!

Thanks... Maybe i should just use REDtek
