If your Oil Change Warning Light is on, it means your vehicle is due for an oil and filter change. This light is triggered by mileage, time intervals, or an oil quality sensor, depending on the vehicle. Ignoring the warning can lead to dirty oil circulating in the engine, causing wear and potential damage.

What does it mean if the Oil Change Warning Light is on?

This light is a maintenance reminder that your engine oil has reached the end of its service life. It does not usually indicate a critical fault but signals that an oil and filter change is required to maintain engine health.

Common causes of the Oil Change Warning Light

• Engine oil has reached its mileage or time limit
• Oil quality sensor detects degraded oil
• Missed or overdue service interval
• System not reset after last oil change

Why do you need to fix this problem quickly?

Delaying an oil change allows old, dirty oil to circulate in the engine. This reduces lubrication, increases friction, and can eventually cause overheating or engine failure. Fresh oil keeps your engine running smoothly and efficiently.

How do you know when to get it checked?

You should book an inspection or oil service if:

• The Oil Change Warning Light stays on after starting the engine
• The light appears alongside the Check Engine or Oil Pressure Warning Light
• You cannot recall your last oil change
• Your oil looks black or gritty on the dipstick

What happens during an assessment?

A mechanic will:

1. Check engine oil condition and level
2. Confirm if an oil and filter change is due
3. Drain old oil and replace the oil filter if required
4. Refill with the correct type and grade of oil
5. Reset the oil change interval reminder

How much does it cost to fix?

An oil and filter change typically costs $150–$250, depending on the oil type and vehicle requirements.

Is it unsafe to drive with the Oil Change Warning Light on?

Not immediately, but driving long-term without changing the oil can severely damage the engine. The warning should be addressed as soon as possible to maintain reliability and avoid costly repairs.
