How to Drain Oil from a Car?
2 Answers
Methods for draining oil from a car include: 1. Draining oil from the fuel filter under the car body or by opening the oil drain screw under the fuel tank; 2. Alternatively, you can remove the engine's return oil pipe, start the engine, and collect the oil while it's running. However, extreme caution is required to prevent oil from splashing, especially onto the ignition system, as it can easily cause a fire; 3. Remove the fuel inlet pipe, locate the fuel pump relay, use wires to bridge the fuel pump relay to activate the fuel pump, and collect oil from the engine's fuel inlet pipe. This is a common method for draining oil in fuel-injected gasoline vehicles; 4. You can also use a specialized fuel tank oil extractor available on the market for oil extraction. When oil needs to be drained, you can also visit a repair shop or a 4S store to use professional equipment for oil draining.
Draining oil is the process of changing the engine oil. First, drive the car for a few minutes to warm up the engine, which thins the oil and makes it easier to drain. Then, use a jack and jack stands to lift the car securely—this is especially important, as it can be dangerous if the car collapses. Locate the drain plug at the bottom of the engine, place a large pan underneath to catch the oil, and slowly loosen the drain plug with a wrench. Remember to stand sideways to avoid the oil spray direction, as hot oil can cause burns if it splashes on your skin. Allow the oil to drain completely for about ten minutes, during which you can also unscrew the oil filter and replace it with a new one. Finally, clean the oil pan drain hole, install a new gasket, and tighten the drain plug. Once everything is done, refill the engine with fresh oil to the appropriate level, start the engine, and let it run for a few minutes before checking the oil level again. A reminder: used oil must be properly recycled—dumping it carelessly can pollute the environment. Always wear anti-slip gloves and safety goggles during the process—safety comes first.
