How to Extract Engine Oil?

Extracting engine oil method: First, prepare a large medical syringe and connect it with a plastic tube used for intravenous drips. Then, pull out the oil dipstick directly, insert the plastic tube into it, and finally operate the syringe to extract the excess oil until the oil level is within the normal range. Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in base oil, mainly containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. Engine oil is used for lubricating internal combustion engines. The main functions of engine oil are to reduce friction and wear of moving parts, remove sludge and paint in the engine, neutralize acids produced from fuel and lubricant oxidation, improve the sealing of piston rings, and cool the engine by carrying away heat from moving parts.
I've been in the auto repair industry for over a decade, and I'm very familiar with oil extraction. The preferred method is using an oil extraction pump. Drive the car for a few minutes to warm it up, then turn it off and wait until the engine is warm but not too hot to touch—this ensures good oil flow. Locate the dipstick hole, remove the dipstick, and insert the tube, making sure to check the manual for the correct depth to avoid getting stuck. Connect an electric pump to a container and slowly extract the oil. The whole process is clean and efficient, avoiding the mess of oil dripping on the floor like with traditional draining. After extraction, check the oil level, and don’t forget to dispose of the used oil properly—take it to a dealership for eco-friendly recycling. For tools, I recommend buying a reliable pump brand, as cheaper ones often fail to extract all the oil. This method is especially great for low-clearance vehicles—it's quick, safe, and even beginners can do it.
