No, the 1994 Mercury Sable does not use R12 for recharging the A/C unit. The 1994 Mercury Sable uses R134a Freon.
R134a freon............
The only freon available is R134a. Your car most like came with R12. That means it will have to have the system evacuated at a shop, and then be converted to the R134a. Look at the fittings where the freon is to be introduced to the system....if they are screw on, then your car needs to be changed over to the newer refrigerant....if they are quick connects, you simply need to add R134a.
Unless it has been converted over to R134 it came with R12. I suggest you convert it to R134a. R12 is very expensive.
All vehicles manufactured for sale in the US after 1995 use R134a.
You should be able to find a sticker on the underside of the hood that will tell you. It should be R134a.

The amount of Freon you will need to fill your 2001 Mercury Sable air conditioning system is dependent upon how low the Freon level is. A recharge kit will have a gauge to tell you when the system is full.
Listed on the A/C placard. More than likely R134a
