For this reason, it is recommended to wait 20 minutes after starting up the engine to gain an accurate PSI reading. Since oil becomes thinner when it heats up, and thicker as it cools down, the oil pressure in the engine may be higher than normal during start-up. The temperature of the engine also has an effect on oil pressure. If the oil is too viscous or not viscous enough, it might be the wrong oil for your engine. Changing the viscosity grade to a thicker or thinner oil has an effect on the oil pressure. Oil quality and viscosity: When oil is thicker (i.e: more viscous) it faces more resistance when passing through the engine's passages, leading to higher oil pressure.If the relief valve experiences a malfunction, the oil pressure can quickly rise to a level that is not safe for the engine. Usually, these valves are set up to open and allow oil through once the pressure reaches a certain level of PSI. Relief valve malfunction: The purpose of a relief valve is to provide a place for the oil to flow when the pressure gets too high.The resistance the oil faces in flowing through a partially or completely obstructed passage could be one reason for high oil pressure. If these passages become blocked, the oil would not be able to pass through efficiently and effectively lubricate all parts of the engine.

Blocked passages: Once the oil has passed through the filter, it flows through a series of passages to the crankshaft.

This leads to more resistance and higher oil pressure. Over time, particles from dust, soot, rust, and gum get deposited in the filter and begin clogging the system.

Dirty or contaminated oil filter: The oil filter is there to filter out impurities from the engine oil.

This can be diagnosed with a manual oil pressure tester, either at home or by a mechanic. 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. When the engine is cold, it is normal for the oil pressure to be higher. 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. What are the causes of high oil pressure? 1 pounds per square inch (psi) is equal to 6.8947572932 kilopascals (kpa) 2 kilopascals (kpa) is equal to 0.29007547545908735 pounds per square inch (psi) Psi to kpa Formula: The formula for is: kPa psi x 6.89475729. 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. 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. A PSI over 80 is usually considered too high for the engine to properly be protected from damage. Since the oil pressure depends on how much resistance the oil faces when flowing through the passages, factors like the size of the engine, the diameter of the bores, and the viscosity of the oil have an impact on oil pressure. To an extent, oil pressure is required for the oil to be able to reach all components of the engine, however if the oil pressure reading is outside of this range, it is usually considered too high or too low. However, we can use Bernoulli's equation for an incompressible fluid to calculate the flow rate in GPM if certain other variables are known.īefore going further, let us first try to understand what Bernoulli's equation is.The ideal oil pressure varies depending on the car brand and model, but generally, the ideal oil pressure is between 25-65 PSI.

Since PSI is a measure of pressure and GPM is a measure of flow rate, we can not directly convert one into another. One US gallon per minute is approximately equal to 6.309 × 1 0 − 5 m 3 / s 6.309 × 10^ 6.309 × 1 0 − 5 m 3 /s. GPM or gallons per minute is a unit of flow rate, i.e., it specifies how fast a liquid (for example, water) moves through a pipe or pump. It is very commonly used in measuring pressure in industries and everyday life, for example, tire pressure, fire hydrant pressure, etc. One psi is approximately equal to 6894.76 pascals (the SI unit of pressure is pascal or Pa). Thus, a more accurate term for psi would be pound-force per square inch ( lbf/in 2). We can define 1 psi as the pressure due to a force of one pound-force applied on an area of one square inch. PSI or pounds per square inch is a unit of pressure.
