    15-20 is normal oil pressure on a hot engine, they run it low to save on fuel. don't worry about it it won't hurt a thing.

If car has a lot of miles you might be dealing with worn main bearings in the engine.

It sounds like the oil pressure switch has failed. It is only an on/off switch that trips at about 15 - 17 PSI, the reading displayed on the dash is created by the computer based on the pressure switch being closed and the engine RPM.

The oil pressure lite came on oil is full slow revs cause drop in pressure

The first thing to determine is whether the oil pressure sending unit is bad or the engine actually has low oil pressure. To determine that you can remove the sending unit and adapt a mechanical oil pressure gauge in the hole. You should have a minimum of 20 lbs. pressure at idle and 40 lbs. above 1,000 rpm on a warm engine. If the pressure readings are good, replace the sending unit; if not, you have an internal engine problem.

Replace the oil pressure sending unit its giveing a false reading . The problem is when the engine is cold the oil pressure is low and it takes a little time to build up whem cranking the engine and that sends a signal to the computer PCM /VCM what ever but your 40 to 60 lbs oil pressure is graet its ideal .The unit switches when the oil pressure is high enough to trip the switch inside the sending unit and that is sent to the vehicle control module

Oil pressure gauge reads 40 or half pressure

on general motors engines all the way down to 15lbs of oil pressure is acceptable i prefer 30 but if the 40 you have down is the lbs of pressure your in good shape brand new engines generally only have about 45lbs of pressure

Oil gauge drops to 0 after driving about 30 min. However it still runs fine with no noise. I had the sensor changed and it still does the same thing.

Ok if you have replaced the oil pressure switch, you might want to have a shop put a guage on it, and see if it happens, while the gauge is on the vehicle..Just to get an accurate reading of the pressure from the oil pump itself....Your oil pump maybe going bad, and it is giving you intermidiate warnings...Another way you can check yourself, is let the vehicle run, and while the engine is running, keep checking the oil level on the dipstick, and make a mark of where it is...And when your gauge drops to 0, check it some if the level is the same, then either your oil pressure switch is defected ( evev though you changed it already).. or your instrument panel is going bad... But if the level drops, when that happen, then you know for sure that your oil pump is bad... Goodluck..

Oil gauge goes up and down.

If grounding the dash does not work, try putting a mechanical gauge on it and reading actual oil pressure. Pressure does change while driving, but should not wander. With mechanical gauge, check that running hot at idle (in gear if automatic) pressure should not drop lower than 15psi (I'd rather see 20) High reading should be around 40 -50 but no higher.Low pressure indicates a loss of supply or bad bearing on the crankshaft, high pressure may be caused by sticking pressure relief or restriction in an oil passage.
