Re: oil pressure light comes on
MINE DID THE SAME THING, IT TO SET FOR A WHILE, ITS NOT LOW ON OIL , ITS LOW OIL PRESSURE,JUST A VERY LITTLE(IF YOUR ENGINE DOESN'T HAVE EXCESSIVEMILEAGE ON IT), AND IT WILL MOST LIKELY CLEAR UP IF U CHANGE THE OIL AND ADD A CAN OF 'RESOLVE TO THE OIL,I HAVE A 4.6 AND I PUT A CAN IN EACH TIME ITS CHANGED.IT HELPS BRING BACK THE CYLINDER WALLS AND BEARING FACES,SO GIVE IT A GO . GOOD LUCK TO U..

The oil light comes on when the oil pressure sensor detects low oil pressure. The amount of oil has little to with it, although very low oil levels can cause loss of oil pressure. Since you aren't getting knocking, chances are the oil pressure sensor is defective. Replace it and monitor the situation closely. This could be a serious condition if allowed to escalated and it turns out to be an oil pressure issue.
The oil light indicates low oil PRESSURE, not oil VOLUME. BUT, I have had an oil pressure sending unit go bad on me before, indicating low oil pressure while in fact oil pressure was fine. If your oil fill cap (where oil is added to engine) is on a valve cover, remove cap while engine is running. If you get an oil mist or oil spray out of it, or if you can see oil spraying when looking down hole (use a flashlight), then you have oil pressure, and the oil light sending unit probably is bad and needs replacing.
car needs oil pressure or bearings will wear out in short time. Do not drive or start engine with this light on. Might only be pressure sending unit. Can replace sending unit and start briefly to see if problem resolves. If light still stays on, shut off engine and have oil pump replaced.
You need to verify that oil pressure is ok.
They sell gauge at the parts store which has to be connected to the engine block via oil pressure sender hole.
For that , take out oil pressure sender(unscrew) and screw the gauge in to the hole (con thread).Run the engine and see if pressure is ok at idle and on higher RPM.Gauge suppose to have scale (norm. , low , high ).If oil pressure within specs , repl. oil pressure sender.
Or just replace oil pressure sender and see if that helps.They are not expensive ~ $30.00 , gauge probably the same money.
