Today, I went to check my oil level after shutting off my car, and I noticed a strange buzzing noise. The buzzing occurs every 10ish seconds and lasted for about 5 seconds. The buzing continued for about ten minutes after shutting off my car. I have no idea what it is! For the first time too, my oil pressure fluctuated (but never went below 30 psi) while driving.
