2 Answers
Mercedes-Benz e300 engine oil model is 5W40. The following are related introductions: The role of engine oil: lubrication, sliding between the piston and cylinder, between the main shaft and bearing bush to prevent wear of parts; auxiliary cooling; cleaning carbon deposits and sludge on engine parts; sealing to prevent gas leakage and the entry of external pollutants; rust and corrosion prevention; shock absorption; anti-wear. Introduction to Mercedes-Benz: Mercedes-Benz is a world-renowned luxury car brand. In June 1926, Daimler and Benz merged to form Daimler-Benz, and cars named Mercedes-Benz represent high-quality, high-performance automotive products. In addition to high-end luxury cars, Mercedes-Benz is also the world's most famous manufacturer of buses and heavy-duty trucks. Mercedes-Benz is a company under the Daimler Group (Daimler AG).
Last time I serviced my E300, I specifically researched the engine oil issue. Mercedes-Benz has quite strict requirements for oil—it must be fully synthetic oil certified with MB229.5 or MB229.71. The dealership commonly uses 0W-30 viscosity, which ensures smooth cold starts and excellent high-temperature protection. The key to choosing oil is to look for the Mercedes certification logo on the bottle—don’t be fooled by marketing terms like 'Mercedes Special.' I currently use Mobil 1 Gold, which delivers more responsive performance than the factory-fill oil. Remember not to casually use 40-viscosity oil—new engines have high precision, and excessive viscosity will increase fuel consumption. The refill amount is around 6.5 liters per service, and oil extraction is more thorough than draining. Regular oil changes are really important—I drive aggressively but stick to changing every 7,500 km, and after five years, the engine condition is still almost like new.
