Oil Change Light: What It Means
Written by Muneeb Rana · Last updated 21 October 2026
Quick answer: An oil change light, often an amber 'maintenance required', wrench or oil-life message, is a reminder that a scheduled oil change or service is due. It isn't an emergency. A red oil-can symbol is different: that's the oil pressure warning, which means stop driving. After a service, reset the reminder using the steps in your manual.
TL;DR
- Amber reminder = service due soon.
- Red oil can = low oil pressure: stop safely.
- Reset the reminder after each oil change.
The oil change light confuses many drivers because cars show it in different ways. Here's how to tell the reminder from the warning, what to do, and how resets usually work.
Reminder vs warning
| Oil change reminder | Oil pressure warning | |
|---|---|---|
| Colour | Amber/yellow or a text message | Red |
| Symbol | Wrench, 'MAINT REQD', 'Oil life 5%' | Oil can with a drip |
| Meaning | Service is due | Oil pressure too low |
| What to do | Book an oil change | Stop safely, switch off, check oil |

How the reminder works
Some cars count down a fixed mileage after each reset; others use an oil-life monitor that estimates oil condition from engine data. Either way it's a timer, not a sensor reading the oil. If you change the oil but nobody resets it, it'll come on again early.
How to reset it
Common methods: a menu in the instrument cluster or infotainment screen ('Maintenance' or 'Oil life' reset); or a sequence such as ignition on, press and hold the trip button until the light flashes. Methods vary by model, so follow your owner's manual. Shops usually reset it for you.
Keep your own reminder
Dashboard reminders reset to a default that may not match your oil or driving. Use the oil change interval calculator, log each change and set a reminder with CarO's oil change reminder. See how often to change oil and the full warning lights guide.

FAQ
What does the oil change light mean?
That a scheduled oil change or service is due. It's a reminder, not a fault.
Can I drive with the oil change light on?
Yes, for a short while; book an oil change soon. A red oil pressure light is different and means stop.
How do I reset the oil change light?
Usually through a dashboard menu or a button sequence. Your owner's manual has the exact steps.
Why did my oil change light come on early?
It may not have been reset at the last change, or the oil-life monitor detected harder use, such as short trips or towing.
Is the maintenance required light the same as the check engine light?
No. The maintenance light is a service reminder; the check engine light means the engine computer found a fault.
