R12 unless it has been retrofitted. I would suggest have it changed, as the cost of R12 is prohibitive.
The 1992 Oldsmobile Cutlass Supreme uses R12 freon and needs 36 ounces. R12 is no longer being made, but is still being recycled and is still available through online auctions.
A 1995 Cutlass Supreme should use R12 freon. The fittings are different between R12 and R134 so that they can not be accidentally swapped.
It came with R12. Due to the high cost of R12, I suggest you convert it to R134a.
R12
most cars use about two cans of r12 refrigerant but a qualified tech should be checking your a/c
It came from the factory with R12. Due to the cost of R12 I suggest you have it converted to run on R134. Have the leak fixed and convert it to R134 and save yourself some big money. R12 is no longer in production, and is very, very, expensive.
2.87 lb of R12 that spec is from the owners manual
R12
1970 to 2006 maybe 2005
Approximately about 22 0z of freon, which is about 1.4 roughly in lbs.
Would have been built for R12, can be converted to R134a.
