What Happens When a Car Lacks Engine Oil?

[JacksonDella]

When a car lacks engine oil, the following situations may occur: 1. The engine noise increases; 2. It may cause high water temperature, valve noise, knocking sound, cylinder scoring, and damage to the mechanical parts of the engine. Here are the functions of engine oil: 1. It allows sliding between the piston and cylinder, as well as between the crankshaft and bearings, preventing part wear; 2. Assists in cooling and temperature reduction; 3. Cleans carbon deposits and sludge from engine components; 4. Seals to prevent leaks, stopping gas leakage and the entry of external contaminants; 5. Prevents rust and corrosion; 6. Provides shock absorption and cushioning; 7. Offers anti-wear properties. Additional Information: The steps for changing engine oil are as follows: 1. Lift the car, remove the undercover, and place a container of about 10 liters under the oil drain plug; 2. Unscrew the drain plug, use an air gun to blow for two minutes at the oil filler port, then tighten the drain plug after the oil is fully drained and check for leaks with a tissue; 3. Reinstall the undercover, lower the car, and use a funnel to add new oil through the filler port.
