Why Does the Low Engine Oil Light Come On?
Before diving into the reset process, it’s helpful to understand why the low oil light appears in the first place. This warning light is part of your vehicle’s onboard diagnostic system. It’s designed to alert you when oil pressure drops below a safe level or when the oil level is too low.

There are two main reasons the light might come on:
1. Low Oil Level
This is the most common cause. Over time, engine oil breaks down and evaporates slightly, and small leaks can develop. If you haven’t changed your oil in a while, the level may have dropped enough to trigger the sensor. Always check the dipstick to confirm.
2. Low Oil Pressure
Even if the oil level is fine, low pressure can trigger the light. This could be due to a failing oil pump, a clogged filter, or using the wrong oil viscosity. Low pressure means oil isn’t circulating properly, which can lead to engine damage.
Regardless of the cause, the first step is always to check your oil level using the dipstick. Park on level ground, turn off the engine, and wait a few minutes for the oil to settle. Pull out the dipstick, wipe it clean, reinsert it fully, then pull it out again. The oil should be between the “min” and “max” marks. If it’s below “min,” add the recommended oil type until it reaches the proper level.
Only after confirming the oil level is correct should you attempt to reset the light. Resetting without fixing the underlying issue is dangerous and could mask a serious problem.
General Steps to Reset the Low Engine Oil Light
While the exact method varies by vehicle, most modern cars follow a similar pattern. Here’s a general process that works for many makes and models:
Step 1: Turn the Ignition to the “On” Position
Insert your key and turn it to the “on” position—this powers up the dashboard and electronics, but does not start the engine. You should see all the warning lights illuminate briefly. Do not start the car yet.
Step 2: Locate the Reset Button or Menu
Some vehicles have a physical reset button near the instrument cluster, while others use the trip odometer or information display controls. Common locations include:
- The trip odometer stalk (the small lever on the steering column)
- The “info” or “menu” button on the dashboard or steering wheel
- A dedicated “reset” button near the speedometer
Step 3: Navigate to the Oil Reset Option
Use the controls to scroll through the menu options. Look for something like “Oil Life,” “Service Reset,” or “Maintenance Reset.” Press and hold the button or follow on-screen prompts to enter the reset mode.
Step 4: Confirm the Reset
Once you’ve selected the oil reset option, you’ll usually be asked to confirm. Press and hold the button again, or follow the instructions on the display. The system will reset the oil monitoring system, and the light should turn off.
Step 5: Turn Off the Ignition and Restart
After the reset is complete, turn the key back to the “off” position. Wait a few seconds, then start the engine. The low oil light should remain off. If it comes back on immediately, there may still be an issue with oil level or pressure.
Remember: these are general steps. Always refer to your owner’s manual for the exact procedure for your vehicle.

Common Mistakes to Avoid
Even simple tasks can go wrong if you’re not careful. Here are some common mistakes people make when resetting the low oil light—and how to avoid them.
Resetting Without Checking Oil Level
This is the biggest mistake. The light is there for a reason. If you reset it without adding oil, you could be driving with insufficient lubrication, risking engine damage. Always check the dipstick first.
Starting the Engine During the Reset
Most reset procedures require the ignition to be on but the engine off. Starting the car can interrupt the process and prevent the reset from working. Keep the engine off until the reset is complete.
Using the Wrong Button or Menu
Some drivers press random buttons hoping to find the reset option. This can confuse the system or trigger other functions. Use the correct controls as outlined in your manual.
Not Waiting for Confirmation
After resetting, the light should turn off immediately or after a few seconds. If it doesn’t, don’t assume it worked. Recheck the steps or consult a professional.
Ignoring Persistent Warnings
If the light comes back on shortly after resetting, there may be a deeper issue—like a faulty sensor, oil leak, or mechanical problem. Don’t ignore repeated warnings.
Troubleshooting: What to Do If the Light Won’t Turn Off
Sometimes, despite following the steps correctly, the low oil light remains on. Here’s what to do:
Double-Check the Oil Level
Use the dipstick to confirm the oil is at the correct level. If it’s low, add the recommended oil type. Wait a few minutes, then try the reset again.
Verify the Oil Type and Viscosity
Using the wrong oil (e.g., 10W-30 instead of 5W-20) can affect pressure and trigger the light. Check your owner’s manual for the correct specification.
Inspect for Leaks or Damage
Look under the car for oil stains or puddles. A leaking gasket, oil pan, or filter can cause low oil levels. If you spot a leak, have it repaired before resetting the light.
Check the Oil Pressure Sensor
A faulty oil pressure sensor can send false signals. If the oil level and pressure are normal but the light stays on, the sensor may need replacement. This is a job for a qualified mechanic.
Try a Second Reset Attempt
Sometimes the first attempt doesn’t work. Turn the ignition off, wait 30 seconds, and try the reset procedure again. Make sure you’re following the steps exactly.
Use an OBD2 Scanner (Advanced Option)
For persistent issues, an OBD2 scanner can read diagnostic trouble codes and reset the oil light electronically. This is useful for modern vehicles with complex systems.
Visit a Mechanic
If none of the above works, it’s time to see a professional. There could be an electrical issue, a failing oil pump, or a problem with the engine control unit (ECU).
When to Call a Professional
While resetting the oil light is usually a DIY-friendly task, there are times when you should seek expert help:
- The light comes back on immediately after resetting
- You notice knocking or ticking sounds from the engine
- The oil level drops rapidly between changes
- You’re unsure about the correct oil type or reset procedure
- The dashboard shows other warning lights (e.g., check engine, temperature)
A mechanic can perform a full inspection, test oil pressure, and diagnose any underlying issues. It’s always better to be safe than sorry when it comes to engine health.
Preventing Future Low Oil Warnings
The best way to deal with the low oil light is to avoid it altogether. Here are some tips to keep your engine properly lubricated:
Follow the Manufacturer’s Oil Change Schedule
Most vehicles need an oil change every 5,000 to 7,500 miles, but check your manual. Some newer models can go up to 10,000 miles with synthetic oil.
Check Oil Level Monthly
Make it a habit to check your oil level once a month. It only takes a minute and can catch problems early.
Use High-Quality Oil and Filters
Cheap oil breaks down faster and may not provide adequate protection. Use the oil grade recommended by your manufacturer and replace the filter with every change.
Watch for Leaks
Regularly inspect your driveway or parking spot for oil stains. Early detection can prevent major repairs.
Monitor Dashboard Warnings
Don’t ignore warning lights. Address them promptly to avoid costly damage.
