Hold on a minute. It is not free on, it is freon, and your Neon contains no Freon. It contains R134a. Take this car to a professional and have the A/C serviced by someone who has the proper equipment, and knowledge to fix the leak, and properly charge the system. Otherwise, you may just ruin a perfectly good compressor and end up spending way more money. Take it to a pro.

Why would you want to even consider doing this? R12 is no longer in production and as such it cost almost 4 times as much as R134. But to answer your question, use R12 in a R134 system and you will destroy the compressor as the oil is not compatible with R134 oil.
If you mix r12 with r134 air conditioning system, it will cause a high pressure in your airconditioning system and eventually damage the compressor and the evaporator. R12 is only for r12 aircon and something with r134, it can't be mix.
Uses no Freon which is R12. Uses R134 refrigerant.
First of all, you don't use R12. Rather, R134 which has the oil included.
Yes, it should have R134. Look on the A/C evaporator or on the compressor. it should be listed there.
If your vehicle is a 1994 or older is contains R12. 1995-96 It man contain R12 or R134. After 1996 it will contain R134. It is listed on a label near the compressor dryer. Engine size means nothing.
If the AC compressor is engaging it could be the heater control valve is stuck open. If the AC compressor is NOT engaging you probably have a problem with the controls, a sensor or the compressor.
Follow larger hose from air compressor usually by passenger side firewall near accumulator/drier
