An oil warning can mean routine maintenance is due, the engine is low on oil, or the lubrication system may have a serious problem. These alerts are not interchangeable.
An oil-change reminder generally means it is time to schedule maintenance. A low-oil-level warning means the engine may not contain enough oil. An oil-pressure warning can mean the engine is not receiving adequate lubrication and may require you to stop immediately.
Symbols, colors, and instructions vary by vehicle. Always follow your owner’s manual.
Quick Guide: Which Oil Warning Is On?
| Warning | What it generally means | What to do |
|---|---|---|
| Oil-change or oil-life reminder | Scheduled service is approaching or due | Schedule an oil and filter change |
| Low-oil-level warning | The engine may not contain enough oil | Check the level using the owner’s-manual procedure |
| Oil-pressure warning | The lubrication system may not be maintaining adequate pressure | Stop safely, shut off the engine, and follow the owner’s manual |
What Does the Oil-Change Light Mean?
A message such as “Change Engine Oil Soon” is a maintenance reminder. It does not usually mean the engine has suddenly lost oil pressure.
Many vehicles use an oil-life monitor to estimate when service is due. Chevrolet, for example, directs drivers to change the oil and filter soon after its “Change Engine Oil Soon” message appears.1
When the reminder appears, schedule an oil and filter change and make sure the monitor is reset after service. Continue watching for separate oil-level or oil-pressure warnings.
An oil-life percentage is not an oil-level reading. A vehicle can have remaining oil life but still be low because of a leak or oil consumption.
What Does the Oil-Pressure Light Mean?
The oil-pressure warning often resembles an oil can, but its appearance and wording vary. It may say “Low Oil Pressure,” “Oil Pressure Low: Stop Engine,” or something similar.
This warning is more urgent than an oil-change reminder. Ford instructs drivers to stop as soon as it is safe and switch off the engine when the engine-oil warning illuminates while driving. Chevrolet similarly warns drivers not to restart an engine displaying an “Oil Pressure Low/Stop Engine” message because operating with low pressure can damage the engine.2,3
If the warning remains on while the engine is running:
- Pull over in a safe location.
- Shut off the engine.
- Follow the instructions in your owner’s manual.
- Arrange assistance if the vehicle should not be restarted or driven.
Do not assume the warning simply means the oil is due for replacement.
What Does a Low-Oil-Level Warning Mean?
Some vehicles have a separate low-oil-level warning. It means the amount of oil in the engine may be below the intended range. Toyota, for example, distinguishes a low-oil-level message from a low-oil-pressure warning.4
Park safely on level ground and follow the manufacturer’s procedure for checking the oil. If it is low, add only the required viscosity and specification, and avoid overfilling. Have the vehicle inspected if the level repeatedly drops.
Oil level and oil pressure are different measurements. Adding oil may correct a low level, but it will not repair a failed pump, damaged component, faulty sensor, or another cause of low pressure.
Can You Drive With an Oil Light On?
It depends on which alert is displayed.
Oil-change reminder: You can generally drive long enough to arrange service, subject to the instructions in your owner’s manual. Do not ignore the reminder indefinitely.
Low-oil-level warning: Check the level promptly. Driving with too little oil can reduce engine protection.
Oil-pressure warning: Lack of oil can permanently damage the engine. Stop safely and shut off the engine according to the manufacturer’s instructions.
When you are unsure which warning is displayed, consult the owner’s manual or arrange assistance rather than guessing.
Why Is the Oil Light Still On After an Oil Change?
A maintenance reminder that remains on after service may not have been reset correctly.
A warning that returns after a reset could mean:
- The reset procedure was incomplete
- The oil level is low
- The system has detected another condition
- An oil-pressure or sensor problem is present
- The displayed warning is not the maintenance reminder
Contact the servicing location if a warning appears after an oil change. If it is an oil-pressure warning, stop the engine rather than driving back to the store.
Will Adding Oil Turn Off the Oil-Pressure Light?
Not always.
Adding the correct oil may help if the engine is low enough to affect pressure. Low oil pressure can also result from:
- An oil leak
- An incorrect or restricted filter
- A worn oil pump
- Restricted oil flow
- Internal engine wear
- Incorrect oil viscosity
- A sensor or electrical fault
Do not add oil without checking the level. Overfilling can create additional problems, and adding oil is not a universal fix for an oil-pressure warning.
What Should You Tell the Service Advisor?
Share the exact symbol or message, whether it stayed on or flickered, and whether the engine was idling or moving.
Also mention:
- Ticking, knocking, smoke, or a burning smell
- Oil spots beneath the vehicle
- Oil recently added
- The date and mileage of the last oil change
Do not try to recreate a serious warning - that's what we're here to help with. A photo of the dashboard message can be helpful.
How Tire Discounters Can Help
For a routine oil-change reminder, Tire Discounters verifies the oil viscosity, performance specification, capacity, and filter required for your vehicle.
Our oil-change service includes:
- Up to five quarts of oil
- A new oil filter
- Tire rotation and balancing
- Tire-inflation adjustment
- Fluid-level checks
- Windshield-washer-fluid top-off
- Wiper-blade check
- Engine-air-filter check
- Exterior-light check
- Roadside assistance, subject to applicable terms
Additional oil and certain vehicle applications may affect the price.5
Tell the service advisor about warning lights, leaks, unusual sounds, or oil added between services. A routine oil change may not resolve a pressure, leak, sensor, or internal engine problem, and additional diagnosis may be needed.
Frequently Asked Questions
Is the oil-can symbol always an oil-pressure warning?
Reference the displayed message/symbol with your vehicle owner’s manual to identify the alert. Often symbols, wording, and colors vary between manufacturers.
Does an oil-life monitor measure how much oil is in the engine?
No. It estimates when maintenance is due and does not replace checking the oil level.
Can old oil cause the oil-pressure light?
Oil condition, level, viscosity, filter restriction, and mechanical problems can affect the lubrication system. A pressure warning requires evaluation rather than assuming an oil change alone will correct it.
What if the oil-pressure light flickers?
A flickering warning may still indicate a pressure, level, sensor, or electrical concern. Follow the manufacturer’s instructions and do not assume the warning is harmless because it turns off intermittently.
Can I drive after adding oil?
Check the level and follow the owner’s manual. If an oil-pressure warning remains on while the engine is running, shut off the engine and arrange assistance rather than continuing to drive.
The Bottom Line
An oil-change reminder means maintenance is due. A low-oil-level warning means the engine may need oil. An oil-pressure warning can indicate an immediate lubrication problem.
Knowing the difference can help you avoid unnecessary concern when routine maintenance is due and avoid serious engine damage when immediate action is required.
Schedule an oil change with Tire Discounters or find a location near you.
If an oil-pressure warning is on while the engine is running, safely stop and follow the manufacturer’s instructions before driving further.
