How to Drain Engine Oil?

[KeeganMarie]

There are two common methods to drain engine oil: one is by removing the drain plug to let the oil flow out, and the other is by using an oil pump. It can be difficult to control the amount of oil flowing out when removing the drain plug. Alternatively, you can purchase an 80 cm long transparent hose from a hardware store to siphon the oil out. Additional information: 1. If thick blue smoke comes out of the exhaust pipe when the car is running, it indicates oil burning. Oil burning refers to engine oil entering the combustion chamber and mixing with the fuel, which can lead to rapid damage of the oxygen sensor, increased carbon deposits in the combustion chamber, higher fuel consumption, and in severe cases, irreversible engine damage. 2. Another way to detect oil burning is to fill the engine with oil, drive for 1000 kilometers, and then weigh the oil filter. Repeat this process several times. If the oil consumption exceeds 0.3 liters per 1000 kilometers, it indicates an oil burning issue.

If you want to change the engine oil yourself, you'll need to prepare an oil drain pan, wrench, and gloves first. Park the car on level ground, and ideally use a proper lift to raise the vehicle. If that's not possible, at least use a jack with safety stands. Locate the drain plug at the bottom of the engine - it's at the most protruding part of the oil pan. Use a socket wrench of the correct size to loosen it counterclockwise. Important: position the drain pan beforehand, and be quick when turning the final half turn - hot oil can shoot out half a meter! Let it drain for about ten minutes, and remember to replace the drain plug washer with a new one before tightening it back to the specified torque. Finally, don't just focus on draining the oil - the oil filter on the side needs to be replaced too, otherwise you'll be mixing new oil with an old filter, which would be such a waste!

Changing engine oil yourself involves three steps: preparation, draining, and refilling. Always operate the jack on a hard surface, and placing wheel chocks adds extra safety. Crawl under the car to locate the hexagonal drain plug – the oil temperature should be around 60°C (too hot to handle, too cold won't drain completely). Use an adjustable wrench to turn the drain plug counterclockwise, allowing 4-5 liters of used oil to drain out. Key point! Before reinstalling the plug, thoroughly clean the threads and ideally replace the copper washer to prevent leaks. Pro tip: change the oil filter simultaneously – hand-tighten it, then give it an additional three-quarter turn. The whole process takes about 30 minutes, but remember to properly recycle the used oil at a repair shop. Never dump it illegally as it contaminates soil.

The key to draining engine oil lies in having the right tools. Opt for an oil drain pan with a spout for easy pouring, and make sure to purchase socket wrenches specifically sized for the engine. If working in a garage, rubber ramps are recommended over jacks for stability and convenience. The drain plug is typically located at the lowest point of the engine—clean any sludge around it before proceeding. The ideal time to perform this task is 10 minutes after turning off a warm engine, using heat-resistant gloves. Be prepared for sudden oil spray when loosening the bolt, so position the pan accurately beforehand. Wait until the oil drips in a steady stream to ensure complete drainage—don’t rush this step. Before adding new oil, inspect the drain hole for aluminum shavings, a telltale sign of engine wear.

Improper operation can lead to trouble in no time. I've seen rookies unscrewing scalding-hot bolts bare-handed, only to have their palms burned and peeled. Others forgot to replace the gasket, turning their garage into an oil pond by the next day. The most dangerous is working with just a basic jack—a collapsing car body can crush ribs. The correct procedure involves wearing goggles to shield against oil splashes to the eyes, and collecting used oil for proper disposal at a 4S shop. Remember not to overtighten the drain plug—aluminum oil pans are prone to stripped threads. The ideal time for an oil change is early morning when the engine is neither too hot nor too cold. If you spot metal shavings in the drained oil, get your engine bearings checked immediately.
