Q: Oil pressure light

asked by on

I'm driving and my cars oil light comes on intermittently , I'm thinking I have enough oil by having added two quarts on Sunday . Then it goes off for a day and the light comes on again . Maybe that I need an oil change , don't know what it is maybe even sensor malfunction just a guess .

My car has 1440000 miles.
My car's transmission is unknown to me.

Hello There, The oil pressure light will usually come on when a few things could be happening. Either the motor is in fact low on oil, the oil pump could be failing or the oil pressure sending unit is not working properly and may be producing a faulty reading. If the engine is in fact low on oil, you may notice the temperature gauge reading above normal temperatures as a result of the lack of sufficient oil in the motor. I would recommend checking the actual oil level in the motor by using the dipstick. Be sure the oil level reaches the "full" mark. If this registers as "full" then you likely have a faulty oil pressure sending unit. Many vehicles also have a safety feature built into the vehicle’s computer system which will shut the engine down completely or trigger a “safe mode” of some kind which will drastically limit the vehicle’s engine power to avoid further engine damage until the oil pressure problem is corrected. I would recommend having an expert from YourMechanic come to your location to take a look at your vehicle to determine what may be causing your low oil pressure light to come on.
