Where is the oil pan screw of Mercedes-Benz C200?

The oil pan screw of Mercedes-Benz C200 is located on the oil pan, usually on the side. Function of the oil pan drain screw: The oil pan drain screw is a screw located at the bottom of the engine oil pan. When the engine requires an oil change during maintenance, this screw is loosened to drain the old engine oil, and then tightened again before new oil is added through the engine's filling port. Reduces engine wear and protects the engine Traditionally, draining engine oil involves removing the drain screw and letting the oil flow out naturally. However, sludge has a certain viscosity and often does not drain completely. About 250-400 milliliters of waste oil deposits remain in the corners of the oil pan and cannot flow out on their own. These deposits mix with the newly added oil and re-enter the engine's lubrication system, causing serious damage to the engine.
When I had my old Mercedes C200 serviced, I noticed the oil pan drain plug is located right at the bottom center of the engine oil pan. You'll need to lift the car or crawl underneath to see it—it's a hexagonal alloy bolt. Last time at the dealership for an oil change, the mechanic specifically warned about controlling the torque when tightening this bolt since the oil pan is aluminum and prone to stripping. It's best to drain the oil when the engine is warm for better fluidity and a thorough drain. There's a copper sealing washer under the bolt that should be replaced with every oil change to prevent leaks. If you're doing it yourself, make sure to have an oil drain pan ready—a Mercedes takes about 6 liters of oil per change.
