What is the oil specification for the Mercedes-Benz C200?

Fully synthetic oil - Shell Helix 5W-40 is the recommended oil specification for the Mercedes-Benz C200. The newer Mercedes-Benz models have higher requirements for oil quality, and you can use engine oils from the three major brands: Shell, Castrol, and Mobil. The viscosity of engine oil changes with temperature, so it's important to pay special attention 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, which means smoother cold starts for the car. The second number represents the oil's kinematic viscosity at 100°C. The higher this number, the better the oil maintains its viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in a Mercedes-Benz C200 is as follows: Wait for the engine temperature to cool down, and also allow the oil to drain back into the oil pan; Use a wrench to loosen the drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; Use a special wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add new oil through the oil filler cap on the engine valve cover. Generally, fill about three-quarters of a standard oil container; Start the engine and let it run for 5 minutes, then check for any leaks around the drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the dipstick and check that the oil level is within the standard range.
I love talking about Mercedes maintenance. After repairing cars for several years, I found that the Mercedes C200 works best with 5W-30 or 5W-40 engine oil, especially those with Mercedes MB 229.5 certification. This viscosity is just right for low-temperature lubrication and high-load operation. Remember to choose synthetic oils from big brands like Mobil or Castrol, and don’t cheap out on the wrong type—otherwise, engine wear will accelerate, leading to oil burning. Change it every 15,000 km or once a year. DIY is simple: check the engine code in the owner’s manual for details, unscrew the oil pan drain plug, drain the old oil, and refill with new oil. Always monitor the temperature gauge while driving. If the oil warning light comes on, check immediately to avoid damage and save money. Good habits can extend your car’s lifespan and improve fuel efficiency.
