Which oil light? The one in the Check Panel only reports a low oil level situation and can be ignored if the level is okay according to the dipstick. But the one in the cluster indicates insufficient pressure and is really important.
The car makes it possible, but the driver makes it happen.

I didn't want to start a new thread but couldn't find an answer to my question.
My oil pressure light started coming on, not the oil level like slo325i, but the pressure on the dash.
It won't do it if I drive the car "normally", but if I start driving spirited, revving up to 5k or so, the light will come on when I'm sitting in idle, as soon as I give it gas, it will go off.
Then if I turn the car off and back on, the light won't come on again until I start driving it hard. I just did an oil change today to try to fix it, no luck. Should I change the sensor or does it sound like a bad pump
Castrol Syntec synthetic oil 10W-50 and a mobil 1 Oil filter.
Like I said I just changed my oil today, the oil I had in there before was synthetic blend and working fine. My oil light started coming on about a week ago.
I drove to Park City today, about 40 minute drive, and back and only had the problem when I stopped completely... will test the sensor but I'm ALMOST positive it's the pump.
The light sounds like it's acting appropriately. Keep in mind that synthetic oil flows much more easily than a conventional oil of the same SAE weight. Even if it has the same effective protection at the bearing, it will flow through the clearance gap more easily and cause a drop in (back)pressure. Warm 10W synthetic in an idling, high-mile M20 will easily cause pressure to be only a few psi. Try switching back to dinosaur 20W50. Or maybe it's time for bearings?
