What Does the Oil Pressure Warning Light Mean?

Have you wondered how your engine uses motor oil? Every car has an oil pump that injects the oil into the tubes and into the engine to lubricate its parts. As the oil moves through the tubes, it builds up a lot of pressure, making it possible for sprayers to operate. If there isn’t enough oil or inconsistency with the oil, it won’t meet the demands of the pump and the pressure will fluctuate. While this instance may seem like a minor inconvenience, a drop in oil pressure can cause extensive engine damage. One of the first ways to tell when your oil pressure has dropped is the oil pressure light.

What Causes a Drop in Oil Pressure?

  • Low oil levels/oil leaks
  • Dirty oil
  • Oil blockage/sludge
  • Failing oil pump

When you catch the oil warning light on your dash, your first instinct should be to check your oil levels. You can do this by simply opening the hood and locating the oil dipstick. Even if your motor oil levels check out, your oil may not be in the best condition. Clean engine oil should be  transparent, amber, and almost runny. If the appearance of the oil looks sufficient, it may be the oil pump. The best way to be sure is by taking your car to Auto DR LLC for an inspection.


Driving with the oil pressure light on is extremely dangerous, and it quickly snowball to many other engine issues. After all, engine oil is the lifeblood of your vehicle. Without it, your vehicle won’t get very far. If you need an oil change or oil pressure warning light related repair, please call or visit our shop soon.
