Why Does My Oil Light Come on When I Have Plenty of Oil in My Car?

Proper auto maintenance can minimize lights activating on your dashboard

Misunderstanding the warning lights on your car's dashboard can be as dangerous an ignoring them. Most cars require an electronic diagnostic from a mechanic to properly diagnose issues, yet it is possible to identify spontaneous problems with oil indicators.

Option 1: Low Oil Pressure

When the oil in a vehicle gets below two quarts, adding more can help it run smoothly again. If you've done this and the light is still coming on, it may mean there's a pressure leak or burning happening that is eliminating oil over time.

Option 2: Sending Unit Has Failed

A full oil reservoir that still triggers an oil light may mean that the oil pressure sending unit is broken.

Become Proactive

Your vehicle may need professional service, as there is no way to guess at some of these issues with any accuracy. Regardless, it is unproductive to ignore this the engine could be damaged by low oil levels.
