Why is my oil light on when I stop?
The dashboard oil light comes on when your engine suffers a drop in oil pressure. Without enough oil pressure, the engine can’t lubricate itself. Continuous lubrication is necessary for the engine to run, so if it’s not adequately lubricated it will seize, and it could stop abruptly, which could cause an accident.
Why does the red oil pressure warning light come on?
Only had it a few hours and the Red Oil Pressure Warning light has started to come on intermittently – on the Rev Counter display. A short time before that the Yellow engine management light came on – on the speedo. Stopped and checked the Oil level and its fine.
Why does the oil light come on when I come to a stop?
This sounds like you have a bearing clearance that is excessive enough to cause the oil pressure at low engine rpms (when the oil pump’s output is lowest) to fall below the oil sending unit pressure threshold for when the light turns on. That threshold is often in the 7 psi range. I would try missleman’s suggestion for a new sending unit first.
What to do when oil pressure light comes on?
My car has an automatic transmission. When the oil pressure light comes on, the engine oil is loosing oil pressure. I recommend performing an oil change and filter change with a good brand filter. If the light is still coming on, then hook up a mechanical oil pressure gauge to the engine and monitor what the oil pressure is doing.
Why does the oil pressure light come on at idle?
If the oil pressure is low at idle and goes up when the engine is revved up, then the rod and main bearings on the crankshaft are worn and need replaced. If the oil pressure is good and is not low at all, then oil pressure sending unit is damaged and needs replaced.
What does it mean when your oil light is red?
What It Your Red Oil Light Means. A red dashboard oil light can mean one of several things, such as: Your oil level is low. Your oil pressure is low. Your oil pressure sending unit (sensor) is faulty.

What does the low oil pressure warning light mean?
This may be a light on the dashboard or, on some vehicles, a message that appears in the driver information center. The low oil level warning light is similar to the low oil pressure warning light.
