What Does the Oil Light on Your Dashboard Mean?

Is your car's oil light on?
You’re driving along when suddenly the oil light on your dashboard turns on. It’s easy to ignore—especially if the car seems to be running fine—but that warning light is one of the most important on your vehicle. At Bruce Brothers Tire & Service in Bethel Park, PA, we’re here to explain what the oil light means, why it turns on, and what you should do when it does.
What Does the Oil Light Look Like?
The oil light usually looks like an old-fashioned oil can with a drop coming out of the spout. It may appear in red or yellow, and in some vehicles, it might include text like “Low Oil Pressure” or “Check Oil.”
Regardless of how it looks, don’t ignore it.
Why Is My Oil Light On?
There are a few common reasons your oil light may be triggered:
1. Low Oil Pressure
This is the most serious cause. Oil pressure keeps your engine lubricated—without it, metal components start grinding, creating extreme heat and wear. If oil pressure drops too low, engine failure is just around the corner.
2. Low Oil Level
Your engine might be running low on oil due to a leak or because it’s burning oil. When levels drop below a safe threshold, the light comes on to warn you.
3. Faulty Oil Pressure Sensor
Sometimes, a bad sensor is the culprit. Even so, you should always take the warning seriously until it’s been properly diagnosed.
4. Dirty or Contaminated Oil
Old, thick, or contaminated oil can’t flow properly through the engine. This can reduce pressure and trigger the warning light—especially if you’ve skipped a few oil changes.
What Should You Do When the Oil Light Comes On?
If you're driving and the oil light turns on:
- Pull over immediately and turn off the engine to prevent damage.
- Check your oil level with the dipstick after the engine cools.
- Top it off if you’re low and you have the right type of oil.
- Call a trusted auto repair shop—like Bruce Brothers Tire & Service—for a professional diagnosis.
Important: Continuing to drive with the oil light on can lead to engine overheating, warping, and even complete failure. Don’t risk it.
