Why does my oil pressure keep fluctuating?
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.
Is it normal for oil pressure to fluctuate when accelerating?
Hi There, This is completely normal for the oil pressure to increase when accelerating. The oil pressure inside the motor increases as the motor works harder. If the fluctuation is extremely erratic, you may have a faulty oil pressure sensor which may also be the cause if it fluctuates too much.
Why is my oil pressure reading so erratic?
Contrary to popular thinking, using an engine oil that is too thin will not make the gauge reading erratic on an engine that is in good mechanical condition. If installing a thicker viscosity oil raises the oil pressure, then something major is wrong inside the 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.
What does it mean when your oil pressure is low?
Seeing a warning light come on indicating your engine has low oil pressure could mean you have a serious problem. Having the right oil, along with the correct level of oil and oil pressure is essential for an engine to run optimally. If the pressure drops too much, an engine can be damaged beyond repair in a matter of minutes.
