Hello! When the car's engine oil is seriously low, a car alarm will be triggered.
The specific principle is that when the engine oil is seriously insufficient, the oil pump cannot absorb enough oil, so the leakage causes the oil pressure in the oil pipeline to decrease. Once the oil pressure falls below the set value, the oil pressure alarm will be triggered. At this time, the vehicle is already in a serious situation of insufficient engine oil. The vehicle cannot continue to drive and needs to be stopped.
If the amount of engine oil is not enough, the vehicle will not issue an oil shortage alarm until it reaches the critical value that triggers the alarm. Therefore, as a car owner, you cannot wait until the vehicle sounds an alarm before thinking of adding engine oil. You must develop a good habit of checking the engine oil frequently.
When car owners usually observe the oil level, the tool they need to use is the oil dipstick. There are usually 2 holes or 2 engraved lines on the oil dipstick. MAX and MIN are written respectively. As long as the oil level is below the MIX mark, it means that the vehicle has insufficient oil and needs to add oil that meets the regulations in time.
