If your Oil Pressure Warning Light is on, it means the engine is not maintaining enough oil pressure to properly lubricate its components. Low oil pressure can cause severe engine wear within minutes, so this warning should never be ignored. The engine should be switched off immediately and inspected before driving further.

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

This light indicates insufficient oil pressure. It may be caused by low oil levels, a faulty oil pump, a clogged filter, or worn internal engine components. Sometimes, a faulty sensor may trigger the light, but it should always be taken seriously.

Common causes of the Oil Pressure Warning Light

• Low or leaking engine oil
• Failing or worn oil pump
• Blocked or dirty oil filter
• Worn engine bearings or excessive internal wear
• Faulty oil pressure sensor or wiring

Why do you need to fix this problem quickly?

Driving with low oil pressure starves the engine of lubrication. This can cause overheating, knocking, or complete engine seizure, often leading to very expensive repairs or replacement. Immediate diagnosis is essential.

How do you know when to get it checked?

You should stop driving and arrange an inspection if:

• The Oil Pressure Warning Light comes on and stays on
• You hear knocking, ticking, or rattling noises from the engine
• The light comes on even after topping up engine oil
• The engine runs hotter than usual
• You notice oil leaks or rapidly dropping oil levels

What happens during an assessment?

A mechanic will:

1. Check the oil level and top up if required
2. Inspect for leaks around the engine and gaskets
3. Test the actual oil pressure with a mechanical gauge
4. Check the oil pump, filter, and pressure sensor
5. Scan the ECU for oil pressure fault codes
6. Recommend repairs such as oil pump replacement, gasket repair, or sensor replacement

How much does it cost to fix?

Minor fixes such as topping up oil or replacing a sensor may cost $100–$250. Oil pump replacement usually costs $600–$1,500+. Severe internal engine damage can exceed $2,500–$5,000+.

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

Yes. Driving with this light on can cause catastrophic engine failure. The car should not be driven until the cause is identified and repaired.
