What is the reason for the engine oil warning light turning on and then off?

[RileyFitz]

The reason for the engine oil warning light turning on and then off is: During a cold start, the oil pressure is too low, causing the light to illuminate. After driving for a while, the pressure returns to normal, and the oil light turns off, which is a normal situation. The functions of engine oil are: lubrication, auxiliary cooling, cleaning, sealing to prevent leaks, rust and corrosion prevention, shock absorption, and wear resistance. The steps to change engine oil are: 1. Lift the car, remove the undercover, and place a container of about 10 liters under the oil drain plug; 2. Unscrew the oil drain plug, use an air gun to blow into the oil filler port for two minutes, then tighten the drain plug after the oil is fully drained and wipe it with a tissue to check for leaks; 3. Reinstall the undercover and lower the car, then use a funnel to add new engine oil into the oil filler port.
