What Does Low Engine Oil Pressure Mean?

While I was driving today, my check oil warning light came on and I thought I could smell something burning. Someone said I might have low oil pressure. What exactly does that mean?

Oh no! I’m so sorry to hear you’re having trouble with your car’s oil. Based on the symptoms, it sounds like your friend is right: you probably have low engine oil pressure.
Basically, low engine oil pressure means there isn’t enough pressure to keep oil flowing to all the parts of your engine. This can cause serious damage fairly quickly. You’ll need to check your oil and possibly have your car towed to a mechanic.
Oil keeps your engine lubricated and running smoothly. Without it, your engine will become severely damaged or even totaled. Watch out for these common symptoms of low oil pressure:
  • Oil warning light is on
  • Burning smell while the engine is running
  • Engine stalling out
  • Engine overheating
  • Unusual noise from your engine
The most common cause of low engine oil pressure is not having enough oil. Check your oil level. If it is low, you’ll need to add more oil. If the level keeps dropping after you refill it, you may have an oil leak.
If your oil level isn’t low, you might have a more serious problem. It could be something as simple as a dirty oil filter or something more complex like a bad oil pump. If this is the case for you, it’s best to take the car to a mechanic and avoid driving when possible in the meantime.
Cars are only one incident away from needing extensive repairs. Make sure you’ve got the
