A 1995 Cutlass Supreme should use R12 freon. The fittings are different between R12 and R134 so that they can not be accidentally swapped.
r134a
R-134A
General Motors changed their passenger cars in 1992 or 1993 so you can be pretty sure that it is R134a. My 1995 CS uses R134a.
it takes r134a freon
134 freon
R134a
1995 Ford Escort La uses 134a Freon.

It does not take freon. The 1995 GMC Vandura uses the new R134a.

Your 1994 Oldsmobile Cutlass Supreme can use any type of SAE certified anti-freeze. If you live in and extreme climates make sure the anti-freeze meets your needs.
