Which freon does a 1993 Cadillac Fleetwood use?

A 1993 Cadillac Fleetwood typically uses R-12 refrigerant, also known as Freon-12. However, due to environmental regulations, R-12 is no longer produced, and many older vehicles have been retrofitted to use R-134a, a more environmentally friendly alternative. It's important to check the specific vehicle's service manual or consult with a professional for the correct refrigerant type used in a particular car.
