Mobil 1 is not immune to the thin oil syndrome. Although it does
maintain viscosity better, if overheated, the oil pressure still will
not be adequate. When the oil is overheated, the oil pump losses its
ability to pump and the bearing clearances will increase further
reducing oil pressure. If the oil level is too high, aeration will
further increase the problem. Make sure the level is correct, (between
the marks, not at the upper mark), and make sure coolant is flowing
through the oil cooler. You also want to check that coolant is flowing
through the small hoses coming off the heads. If you have the plastic
return loop in the engine compartment, the hose connections tend to get
clogged.

Switch my have gone bad or you may simply have a bad connection, wire
broke, connector came loose, wire insulation worns and shorted.  What
RPM does the buzzer come on? That can give clues.

Good Luck,
