If your Oil Pressure Warning Light comes on, it means the engine’s oil pressure is too low. Without sufficient oil pressure, vital engine parts are starved of lubrication, which can cause rapid wear or catastrophic engine failure. This warning should never be ignored, and the engine should be switched off immediately to prevent damage.

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

This light indicates that oil is not circulating through the engine at the correct pressure. It may be caused by low oil levels, a failing oil pump, a clogged oil filter, or worn engine components.

Common causes of the Oil Pressure Light

• Low engine oil level
• Failing oil pump
• Blocked or clogged oil filter
• Worn engine bearings or internal wear
• Faulty oil pressure sensor

Why do you need to fix this problem quickly?

Driving with low oil pressure can cause severe engine damage in minutes. Lack of lubrication leads to overheating, knocking, or engine seizure. Immediate inspection and repair are essential.

How do you know when to get it checked?

You should stop driving and book an inspection immediately if:

• The Oil Pressure Light comes on and stays illuminated
• You hear knocking, ticking, or rattling noises from the engine
• The engine runs hotter than normal
• You notice low oil on the dipstick
• The light comes on even after topping up the oil

What happens during an assessment?

A mechanic will:

1. Check engine oil level and condition
2. Inspect for oil leaks or consumption
3. Test the oil pressure with a mechanical gauge
4. Check the oil filter and oil pump operation
5. Inspect the oil pressure sensor and wiring
6. Recommend repairs such as oil pump replacement, gasket repair, or sensor replacement

How much does it cost to fix?

Costs vary depending on the cause. A simple oil top-up or sensor replacement may cost $100–$250. Oil pump replacement typically costs $600–$1,500+. Severe internal engine repairs may exceed $2,000–$5,000+.

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

Yes. Driving with this warning light on risks catastrophic engine failure. The engine should be switched off immediately and inspected before driving further.
