What could be wrong if oil pressure gauge reads 80 in 1997 Cadillac Catera?

80 psi is a normal reading for a cold engine that has just been started. Around 40 psi is normal after the engine has reached full operating temperature. If you have 80 psi on a hot engine, then you may have restricted oil flow. Change the oil and replace the oil filter with an AC/Delco filter. Make sure you are using the proper weight oil and do not install any aftermarket oil treatments of any kind.
