How to Drain Engine Oil?
2 Answers
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!
