Oil Pressure Light On? What It Means and What to Do
Written by Muneeb Rana · Last updated 21 October 2026
Quick answer: A red oil pressure light means the engine isn't getting enough oil pressure to lubricate itself. Pull over as soon as it's safe and turn the engine off, then check the oil level when it has settled. Driving on with low oil pressure can destroy an engine within minutes.
TL;DR
- Colour: Red.
- Stop as soon as it's safe and switch off the engine.
- Fix the cause rather than just clearing the light, and log the repair.
The oil pressure light is one of the dashboard warnings drivers search for most. This guide covers what it looks like, what it means, how urgent it is and what to do, in plain English. Your owner's manual has the exact symbol and advice for your car.
What does the oil pressure light look like?
| Symbol | An old-fashioned oil can with a drip |
| Colour | Red |
| How urgent | Stop as soon as it's safe and switch off the engine. |
Warning lights follow a rough traffic-light code: red means a serious problem or safety issue, so stop when it's safe; amber or yellow means something needs attention soon; green or blue is information only. See the full dashboard warning lights guide for every common symbol.
What the oil pressure light means
Don't confuse it with an oil change reminder or maintenance light, which is usually amber and just means a service is due. See oil change light.
Common causes:
- Low oil level from a leak or oil burning
- A failing oil pump
- A blocked oil pickup or filter
- A faulty oil pressure sensor or wiring
- Wrong oil viscosity for the engine
What to do when the oil pressure light comes on
- Pull over safely and switch the engine off.
- Wait a few minutes, then check the dipstick with the car on level ground.
- If the level is low, top up with the oil grade in your manual.
- If the level is fine but the light stays on, don't drive; have the car towed or inspected.
- Find and fix the leak or cause, then log it.
Can you drive with the oil pressure light on?
No. If the light stays on after topping up, or the oil level was fine, get the car towed.
If you're not sure, treat it as the more serious case. A tow costs far less than a ruined engine, gearbox or set of brakes. If several warning lights come on at once, that often points to an electrical or charging problem; see the check engine light guide and the battery light page.
How to reset or clear it
Don't just clear the light. Most warning lights go out on their own once the fault is fixed, sometimes after a few drive cycles. Clearing a code with a scanner without fixing the cause only hides the problem until it returns, and it can make an emissions test fail because the car's readiness monitors reset.
Keep a record of warning lights and repairs
Write down the date, odometer reading, what the light looked like, the fault code if you had it read, and what fixed it. If the same light comes back, that history saves diagnosis time and money. In CarO you can log the repair and its cost in the car repair log, and set a follow-up with the service reminder tool. For a routine check that catches problems before a light comes on, use our car maintenance checklist. Related: how to check your oil level and oil change light guide.
