Would have been built for R12, can be converted to R134a.
A 1998 Buick would have been built with R134a.
The original refrigerant installed at the factory in 1973 was R12 (Freon). If it has not been converted to R134a, I suggest you convert it now, if it is leaking and needs repair. R12 is no longer in production and the dwindling supply is very expensive. Much cheaper to convert it to R134a.
It came with R12. Due to the high cost of R12, I suggest you convert it to R134a.
2 pounds of r134a. Not r12.
If if it a 1995 or older then it came with R12 installed. 1996 can be R12 or R134. 1997 up, it has R134/R134a. If you suspect it had R12 look for a label somewhere on the A/C unit signifying it has been converted. If you find it has R12 and is leaking and needs repairing, after the leak is repaired, convert it to R134a. R12 is far too expensive to use.
3.4 pounds of r134a for a day cab r12 is different

Unless it has been converted over to R134 it came with R12. I suggest you convert it to R134a. R12 is very expensive.
It was built with r12. It can be retrofitted to R134a.It was built with r12. It can be retrofitted to R134a.
It came with R12 but due to the price of R12, I would convert it over to R134a. You need to fix the leak before the conversion.
