How much engine oil should be added to the e200?

e200 requires 4.5 liters of engine oil. The official manual for the e200 recommends using engine oil with the specification 5W40. Any oil that meets this specification can be used. If you plan to change the oil during later maintenance, you can choose brands such as Shell, Mobil, Castrol, or Total. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother for the car. The second number represents the kinematic viscosity of the oil at 100°C. A higher number means the oil can maintain its viscosity better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in the e200 is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passages to drain. Use a specialized wrench to remove the oil filter. Apply some oil to the oil seal of the new oil filter and tighten it clockwise by hand. Add the new engine oil through the oil filler cap on the engine valve cover. Generally, fill about three-quarters of the oil container. Start the engine and let it run for 5 minutes. Check for any oil leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs. After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.
I've owned a Mercedes E200 for five years, and changing the oil is a routine task. Generally, the E200's engine requires approximately 6 liters of oil, depending on the year and engine type. For example, pre-2017 models might need 5.8 liters, while post-2018 models could require around 6.2 liters. When I first bought the car, I made mistakes like adding too little oil, which caused loud engine noise, or overfilling, which led to increased fuel consumption and even smoke. So now, I always check the owner's manual to confirm the exact amount before carefully pouring in new synthetic oil using a funnel. Synthetic oil performs better under high temperatures, and I use fully synthetic 0W-40 or 5W-30 types. The recommended oil change interval is every 8,000 to 10,000 kilometers or every six months—don't wait too long to avoid carbon buildup. Remember to replace the oil filter at the same time and drain the old oil thoroughly to protect the engine's lifespan and ensure smoother driving. If you're unsure, use a dipstick to check that the oil level is between the MIN and MAX marks for safety.
