What Your Oil Warning Lights Mean, and What to Do

Your vehicle’s engine is one of its most critical components, relying heavily on motor oil to function correctly. Oil lubricates moving parts, reduces heat, and prevents contaminants from damaging the engine. When there is an issue with the oil system, one or more warning lights will light up on your dashboard to warn you. Ignoring these lights can cause severe damage to your engine.

What Are the Oil Warning Lights For?

1. Low Oil Pressure Warning Light

This light indicates insufficient oil pressure in your engine. Oil pressure is vital for lubricating the engine's fast-moving, precision-made components.

Symbol: This warning light usually appears as an old-fashioned oil can with a drop of oil dripping from its spout.

2. Low Oil Level Warning Light

This light warns that the oil level in your engine is too low. It is triggered by a float in the oil pan that monitors oil levels.

Symbol: Similar to the oil pressure light but often includes a wavy or jagged line beneath the oil can.

Note: Some vehicles in Malaysia combine these functions into a single light. Refer to your owner’s manual for more information.

Why the Oil Warning Lights Can Come On

Here are the most common reasons oil warning lights illuminate and how MyMechanic Malaysia can help resolve these issues:

1. Your Oil Level Is Too Low

Cause: If you haven’t checked your oil regularly or there is a leak or excessive oil consumption, the level can drop dangerously low.

Solution:

Stop driving immediately and turn off the engine.
Let your car sit for 5 minutes to allow the oil to drain back into the pan.
Check the oil level using the dipstick. If it's low, add the correct grade of oil.
Contact MyMechanic for repairs if the lights remain on.

2. Your Oil Pump Is Faulty

Cause: The oil pump circulates oil throughout your engine. If it fails, oil pressure drops.

Solution: Turn off your car immediately and contact MyMechanic for diagnosis and repairs.

3. Blocked Oil Filter

Cause: Over time, contaminants like dirt and debris can clog the oil filter, restricting oil flow.

Solution: Regular oil and filter changes at MyMechanic Malaysia prevent this issue.

4. Faulty Sensor, Wiring, or Warning Light

Cause: A malfunction in the warning system due to a faulty sensor or wiring can trigger the light.

Solution: Visit MyMechanic for a thorough diagnostic to fix any electrical or sensor issues.

5. Oil System Sludge Build-Up

Cause: Poor maintenance or wrong oil usage can lead to sludge formation, clogging the oil system.

Solution: MyMechanic can perform an engine cleaning service and recommend synthetic oil to prevent future sludge buildup.

6. Engine Wear and Tear

Cause: High-mileage engines may develop excessive wear, reducing oil pressure.

Solution: MyMechanic can assess the wear level and recommend repairs or engine replacement options if necessary.
