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. Oil pressure is one of the most important factors contributing to an engine running smoothly and lasting a long time. Engines are complex pieces of machinery, and they have a lot of weight to pull — literally. Having oil in an engine makes sure that all the moving parts are well lubricated and able to function optimally.
When the oil is flowing through an engine, pressures build up. This results in friction, warping, seals breaking, and some other issues. Problems with oil can truly inflict major damage to your vehicle if left unchecked. If the warning light comes on to indicate there is a problem with the pressure, stop your vehicle as soon as possible. To give an idea of what the problem might be, here are 5 of the common causes of low oil pressure in your engine:. If your oil warning light is on and you want to perform some checks yourself, the following information should help:.
The oil level dropping below the minimum dipstick line is one of the most common causes of low oil pressure. Over time, engines burn oil more quickly.
This is due to piston rings wearing, seals leaking, and so on. A PSI over 80 is usually considered too high for the engine to properly be protected from damage. High oil pressure is an indicator that the oil is not able to properly pass through the bores and reach all parts of the engine effectively. An engine that is not lubricated correctly can face sometimes instant wear through friction, damage to its components, and in extreme cases, it can lead to engine failure. Oil pressure sending unit malfunction: The oil pressure sending unit is responsible for measuring the oil pressure and controlling the oil pressure gauge on the dashboard.
When the engine is cold, it is normal for the oil pressure to be higher. However, if the oil gauge reading is at its highest reading even after the engine has had time to warm up, the oil gauge may be defective.
This can be diagnosed with a manual oil pressure tester, either at home or by a mechanic. Pay attention! Your browser is outdated, this can have a negative effect on the user experience. Download Google Chrome.

Obstructed Oil Filter: After the oil leaves the oil pump, it passes through the oil filter. This filter prevents debris and other contaminants from passing through the engine and keeps it clean.
This filter naturally creates a resistance in the oil flow but is not disruptive. As the build-up of debris grows, the restriction of the oil flow will increase. This could result in a completely blocked oil filter through which no oil can pass. To prevent a blockage, the pressure relief valve will open. This valve opens automatically when the pressure exceeds a preset value. The oil will then bypass the oil filter so it can keep on flowing.
This detour reduces the pressure to that of the bypass valve.
