Check if there is too much oil. over filling the engine with oil causes the oil to foam which leads to loss of oil pressure. it could also be the oil pressure sensor

2007 Buick oil light comes on and off at random. Recently changed oil. GTX extended milage. .5w30. Oil level good. Any ideas


Oil pressure sensor, or most likely, oil level sensor, either sensors, wires, or connections.

What can be the problem the oil light stays on on the dashboard but the oil level is ok (endura de)


The oil light refers to oil PRESSURE, not oil level. That said, if the oil pressure is low enough to set the oil light, then you should be hearing rattling noises coming from the engine when it is running. That is not to say that you may not still have a problem. The oil light is nothing to take lightly. If there is an oil pressure problem, engine damage can occur quickly. Check the wiring connection to the oil pressure sending unit. If you suspect that the problem is not really low oil pressure, then change the pressure sensor. It is relatively cheap and the easiest way to verify whether there is a real problem. If the light remains on after the sensor is replaced, have the oil pressure tested with a mechanical gauge to verify that it is low. If it is low, you either have a very worn out engine, or a malfunctioning oil pump system.

I have a 97 supercharged the oil light keep comin stay on while Im driven the oil is full


The oil light is for low oil pressure, not low oil.
You need to have someone check the actual oil pressure with a mechanical gauge or change the oil pressure switch and see it the light still comes on.

Why does my low oil pressure light comes on when making left and right turns


Oil level is probably low. When you turn, your oil splashes to the right or left and your pump is not able to pick up the proper amount of oil to pump. If the level is proper, you might have the wrong grade of oil. Check your owners manual for proper weight for the driving sonditions you are in.

Just had my oil changed and the check engine oil level low light is coming on . But checked it and it's not low , just on the full mark . It comes on everytime I restart the car . how do I fix that ?After...


You have to reset the check engine oil level light. The light is just a 3 month reminder that lets you know when to change your oil. You have to hold the reset button on your dash for more then 5 to 10 sec. The procedure is in the owners manual that came with the car.

Check the fluid level and change the oil if you've used the car 3,000 mi. or more.

Usually low oil pressure lights are red and are more serious than the amber lights.

Past weekend check engine light comes on, engine sounds and feels fine. However the oil pressure is running slightly slow


Check that the oil level is full.If the oil has been in service for more than 4,000 miles, change it. Replace the oil pressure sending unit. If nothing changes, put a mechanical gauge on the engine and read actual oil pressure. Though "acceptable" low pressure is only 5lbs, I would never accept that as safe. Minimum pressure should be at least 20-25psi and normal running pressure between 35 to 45psi.
How low is "slightly low"?
