What is the type of refrigerant used in a 1994 Oldsmobile 98?
It is R134a. Please under NO circumstances use the refrigerant that has stop leak added. If you have to take it to a repair shop and need repairs, it will ruin the equipment that is used to recover the refrigerant. Also, you need to be exact in the amount that is in the system. There should be a sticker under the hood with all of the information on it.
