Why doesn’t my oil light come on when my oil is low?

The oil pressure light is NOT there to remind you it is about time to top-up the oil. Low oil pressure can be caused by several things – extremely low oil is only one of them. Other causes can be a failed (or failing) oil pump, a blocked or damaged oil line, MUCH too thin oil and so on.

Will my car tell me when it’s low on oil?

How low is the oil when the oil light is on?

Sounds like low oil pressure. At high engine speeds, the pressure goes up, turning the light off. When decelerating, the engine speed drops, and so does the oil pressure, turning the light on. Primary suspect would be the oil pump, or the pressure regulator valve that is part of it.

Should you have to add oil between oil changes?

Usually no top up of engine oil is required between oil changes, but if the oil level goes down it could be because of a leak or engine burning up oil due to piston rings faulty or valves leaking oil.

How many miles can I drive after oil light comes on?
