What is the method for checking engine oil pressure?

Engine oil pressure checking method: 1. Unplug the wiring harness connector of the oil pressure sensor, remove the oil pressure sensor, and screw the hose connector of the oil pressure gauge into the threaded hole where the oil pressure sensor was installed; 2. Place the oil pressure gauge in a location where it will not come into contact with rotating or high-temperature engine components; 3. Start the engine and check for oil leaks at the oil pressure gauge connection; 4. Run the engine until it reaches normal operating temperature. Only when the oil pressure value is within the normal range can the oil be ensured to be delivered to all parts of the engine. Pressure that is too high or too low can affect normal operation and even cause damage to the engine.
The method for checking oil pressure is actually quite meticulous. Having driven for over a decade, I've developed a habit of first checking the dashboard: if the oil warning light comes on, it definitely indicates abnormally low oil pressure, and you should pull over immediately for inspection. Next, I pull out the dipstick to check if the oil level is adequate—if it's too low, I top it up with fresh oil. If the light isn't on but something still feels off, like increased engine noise or sluggish acceleration, then it's time to use manual tools: attach an oil pressure gauge to the engine's test port, start the car, and read the pressure value. The normal range is between 50 and 70 psi. If it's lower, it could mean the oil pump is failing or the filter is clogged. Don't underestimate this—prolonged low pressure can wear out bearings and lead to costly engine repairs. Regular oil and filter changes are key to prevention. I check every 5,000 kilometers to avoid the risk of breakdown.
