What is done when the 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.
How does a mechanical oil pressure gauge work?
A mechanical gauge uses a spring that is affected by the pressure of the oil. A coiled tube, called a bulb, attaches to the oil pressure gauge’s outer casing and to linkage at the bottom of the needle.
Why does my oil gauge read too high?
Oil Pressure Gauge Reading Too High. Another common oil pressure gauge problem is a reading that’s too high when your engine is idle or when it’s turned off. The gauge should never read very high when you’re not driving because the engine should be fairly cool due to inactivity.
Can a broken oil pressure gauge be dangerous?
While a broken oil pressure gauge is not a threat to your vehicle, it is too important a tool for you to lose. It alerts you when there’s a real problem going on in your engine.
When does the oil pressure go up or down?
When your engine is idle or when you’ve just started your car, the oil pressure gauge will have a low reading. When the engine starts running and heating up or when you’re already cruising on the freeway, your gauge’s reading should increase.

Do you need an O’Reilly oil gauge?
If you only have a warning light, it is usually possible to add an aftermarket oil gauge if you choose. O’Reilly Auto Parts carries a variety of gauges that will fit any application.
What does the oil pressure read when the engine is off?
With the engine off (low or no oil pressure) the gauge properly reads low/no oil pressure. But with the engine running and oil pressure present, the gauge pegs to the far right, and would most likely burn out the innards of the gauge if left that way for very long.
