When it comes to maintaining the health and longevity of your vehicle’s engine, one of the most critical aspects is ensuring that the oil pressure is within the recommended range. Engine oil pressure plays a vital role in lubricating the moving parts of the engine, reducing friction, and preventing damage from wear and tear. However, many car owners are unaware of how to test engine oil pressure, leading to potential engine damage and costly repairs. In this article, we will delve into the importance of testing engine oil pressure, the different methods for doing so, and provide a comprehensive guide on how to test engine oil pressure like a pro.

The Importance of Engine Oil Pressure
Engine oil pressure is the force exerted by the oil pump to circulate engine oil throughout the engine. The oil pressure is measured in pounds per square inch (PSI) and is typically indicated on the dashboard of modern vehicles. The recommended oil pressure range varies depending on the vehicle manufacturer and the type of engine, but generally falls between 30-60 PSI.
When the engine oil pressure is too low, it can lead to premature wear on moving parts, increased friction, and even engine failure. On the other hand, excessively high oil pressure can cause oil leaks, damage to engine components, and decreased fuel efficiency. Therefore, it is essential to monitor and maintain the correct oil pressure to ensure the longevity and performance of your vehicle’s engine.
There are several methods for testing engine oil pressure, including:
- Using a dipstick
- Using an oil pressure gauge
- Using a scan tool
Using a Dipstick
One of the most common methods for testing engine oil pressure is by using a dipstick. The dipstick is usually located under the hood of the vehicle and is used to check the oil level and pressure. To use the dipstick method, follow these steps:
- Locate the dipstick under the hood of your vehicle.
- Pull out the dipstick and wipe it clean with a rag or paper towel.
- Insert the dipstick back into the oil reservoir and pull it out again.
- Check the oil level and pressure on the dipstick.
However, the dipstick method is not always accurate and may not provide a precise reading of the oil pressure. Additionally, it is recommended to check the oil level and pressure when the engine is cold, as the oil pressure can fluctuate when the engine is hot.

Using an Oil Pressure Gauge
An oil pressure gauge is a more accurate and reliable method for testing engine oil pressure. The gauge is connected to the oil pressure sensor and provides a real-time reading of the oil pressure. To use an oil pressure gauge, follow these steps:
- Locate the oil pressure sensor on the engine block or cylinder head.
- Connect the oil pressure gauge to the sensor.
- Start the engine and let it run for a few minutes to warm up.
- Check the oil pressure reading on the gauge.
The oil pressure gauge provides a more accurate reading of the oil pressure than the dipstick method and is recommended for vehicles with high-performance engines or those that require precise oil pressure control.
Using a Scan Tool
A scan tool is a device that connects to the vehicle’s onboard computer and provides a reading of the oil pressure. To use a scan tool, follow these steps:
- Connect the scan tool to the vehicle’s onboard computer.
- Start the engine and let it run for a few minutes to warm up.
- Check the oil pressure reading on the scan tool.
The scan tool provides a real-time reading of the oil pressure and can also provide diagnostic information about the engine’s performance. However, the scan tool method may not be available for all vehicles and may require a subscription or software update.
