What viscosity oil did you use?

The warning buzzer will sound at close to 2000 rpm if the pressure is not at a certain level
(more correctly, if the oil pressure switch does not ground out).

See the attached PDF.

If you put in a thinner oil than before, then the thinner oil is not producing the same
pressure as thicker oil would.

To eliminate an electrical issue, ground the oil pressure switch wire and see if the
noise & light still come on. If yes, you have a wiring / electrical problem. If no, then you
have an oil pressure switch or oil pressure problem.
