What Are the Causes of Low Engine Oil Pressure?
2 Answers
Reasons and solutions for low engine oil pressure are as follows: 1. Oil pump damage: The connecting pipe from the oil pump to the engine block is damaged, or the gasket is cracked or broken, causing oil leakage. Lift the car and inspect along the pipeline to identify the problem area, then repair or replace it promptly. 2. Insufficient oil: Insufficient engine oil storage leads to low oil pressure. Purchase a bottle of the same oil used during maintenance and add it. Of course, identify and resolve any oil seepage or leakage issues. If the engine is burning oil, please take it to a 4S shop for inspection and repair. 3. Dirty oil: Oil that has been used for too long becomes dirty or viscous, preventing the oil pump from smoothly drawing in and pumping out the oil, resulting in low oil pressure. First, clean or replace the oil pump, then refill the car with new oil. After replacement, ensure the oil quality and strictly adhere to maintenance standards for upkeep.
I've seen low engine oil pressure many times, and there are several main reasons. The most common is insufficient oil, caused by oil pan leaks or oil burning leading to low oil level. Oil pump failure or wear is another major factor - damaged pump blades or increased clearances prevent proper pressure buildup. A clogged oil filter restricts oil flow and drops pressure. Degraded oil viscosity (like using winter-grade oil in summer) makes oil too thin to maintain pressure at high temperatures. Severe internal engine wear, such as worn piston rings or bearing clearances, can also cause oil leakage and pressure loss. I remember a friend's car had low oil pressure warning, and it turned out the oil pump belt had snapped. Ignoring these issues can lead to major disasters like engine overheating or bearing seizure, resulting in costly repairs. That's why I always emphasize oil changes and pressure checks during maintenance, and advise immediate inspection if the warning light comes on while driving - never delay to avoid serious accidents.
