What is the sign of low engine oil in a car?

[MacLilah]

Engine oil is an essential medium for ensuring lubrication and cooling in a car. Once the oil level drops below the minimum limit, the oil warning light will illuminate. The oil warning light is shaped like an oil can with a wavy line underneath. Below is some relevant information about engine oil: 1. Checking the oil level: If the oil indicator light turns yellow while driving, it usually indicates low engine oil. In this case, you should park the car in a safe location, open the engine hood, wait for about 3-5 minutes, then pull out the dipstick to check the oil level. If the dipstick shows the oil level is outside the normal range, you will need to add more oil. 2. Electronic oil level indicator: Some vehicles, such as Audi, BMW, and Mercedes-Benz, do not have a traditional dipstick but instead use an electronic oil level indicator. The oil level will be displayed on the central information screen. Simply add oil until it reaches the standard level. Additionally, if the oil level sensor is faulty, it may cause the yellow oil warning light to illuminate on the dashboard. If the oil level is within the normal range, the issue likely lies with the sensor.
