Flickering oil warning light

Having any dashboard warning light illuminate can be alarming, but when the light keeps turning on and off at seemingly random times, it’s downright frustrating.

Oil light flickering while idle

If your oil light flickers on and off while you are stopped or are idle, there may be a problem with your oil sensor or the oil pressure may be too low. The engine should have at least 5 PSI when not moving, and any less than that will cause the light to flicker on and off. If you notice the light turns off once you start moving, this is most likely the problem. If this is the case, bring your vehicle into see us at Matt Castrucci Mazda so our service technicians can diagnose and fix the problem.

Oil light flickering when driving

If your oil light flickers while driving, your oil levels may simply be too low. Try adding engine oil and seeing if that turns the dashboard warning light off. If adding oil doesn’t help, the next likely cause is worn out engine bearings. This is a cause for concern because it makes the oil pump squirt oil out of places it’s usually contained. If you think this may be the culprit causing your engine light to flicker, bring your vehicle into a certified technician as soon as you can.
