What does it mean when oil pressure fluctuates?
There are rare mechanical problems that can cause an unsteady oil pressure reading. They usually happen right after an engine has been overhauled. If that sounds like you, then suspect a faulty oil pressure by-pass valve or spring inside the oil pump. Valves stick or can get installed wrong on some engines.
Why does my oil pressure gauge keep dropping?
The oil needs changing: Over time, oil breaks down and loses some of its viscosity, causing a low reading on the oil pressure gauge. Worn bearings sometimes cause the oil pressure to show a low reading. The mechanic will change the bearings if needed. A broken oil pump may cause a low oil pressure reading.
What does low oil pressure indicate?
Low Oil Pressure Light On? The low oil pressure light is a warning that there’s not enough oil pressure or that the oil level is too low. This prevents the oil from going through the narrow passages to provide sufficient lubrication. Lack of lubrication can cause the engine to seize up or cause damage beyond repair.
Will thin oil cause low oil pressure?
Using the Wrong Oil Low oil viscosity will lead to your engine suffering from lower oil pressure inside the passageways. This is something that can happen if you switch from the recommended oil for your engine to a higher-grade oil – remember, higher grade oil is not necessary for optimal engine performance.
Can you drive with a faulty oil pressure sensor?
If the dipstick reads that the oil level is fine and the engine sounds like it’s running quietly and smoothly, then the light is probably just the result of a bad sensor. In this case, definitely stop driving until you’ve resolved the issue or you could be facing major and immediate engine damage.
What happens if your oil pressure sensor goes bad?
The Oil Pressure Light is on When this sensor goes bad, it will start to give inaccurate readings. After the readings fall out of specification, a warning light is set. The faster this sensor can be replaced, the less stress you will have regarding the oil levels in your vehicle.
