What kind of oil does the Mercedes 274920 engine use?

[PatrickRose]

Mercedes 274920 engine uses Mobil 1 oil. Mercedes 274920 engine: This is the latest model in Mercedes' current M274 series of engines, belonging to the 2.0T high-power version. This engine has a maximum power of 155kw, a maximum torque of 350 Nm, a maximum power speed of 5500 rpm, and a maximum torque speed of 1250 to 4000 rpm. Introduction to Mobil 1: Mobil 1 is a full synthetic oil brand with multiple proprietary Anti-wear technologies. Mobil 1, a lubricant brand under ExxonMobil, was born in 1974 and has become a globally applied automotive synthetic oil. At that time, due to its design exceeding industry performance standards, it set a new benchmark in the field of lubrication technology. Mobil 1 complies with the latest API SN specification of the American Petroleum Institute and features multiple proprietary Anti-wear technologies, effectively helping to reduce engine wear, keep the engine clean, and meet the needs of modern engine technology and fuel economy with higher standards of engine protection and lubrication performance. Mobil 1 meets automobile manufacturer standards with its Anti-wear technology, providing engine wear protection even under extreme conditions. The low-temperature fluidity of Mobil 1 provides protection for critical engine components under extreme temperatures, thereby optimizing engine performance and extending engine life.

My Mercedes-Benz E-Class is equipped with the 274920 engine, which is quite picky about engine oil. I personally use 5W-40 full synthetic oil, specifically Mobil 1 that meets the Mercedes MB 229.5 certification. I tried other brands of oil before, and the engine sounded noticeably rough during cold starts. After switching to certified oil, the throttle response became much quicker. Turbocharged engines are most afraid of insufficient oil shear resistance, as the oil film can easily break down after prolonged high-speed driving. So never skimp on oil that falls below the 229.5 standard. Now, I change the oil every 10,000 kilometers, and the guys at the dealership say this is the safest approach.

With 20 years of experience in auto repair, I've handled numerous Mercedes-Benz 274 series engines. For the 274920 generation, it's crucial to use MB 229.5 certified oils - either 0W-40 or 5W-40 viscosity fully synthetic will do. Recently, I dealt with a cylinder scoring case caused by using uncertified 10W-40 mineral oil. The turbo runs hot, and conventional oil simply can't withstand the high-temperature oxidation. My go-to brands are Shell Helix Ultra, Castrol Edge, and Mobil ESP, all with complete certifications. Remember not to exceed 12,000 km oil change intervals, and always use genuine OEM oil filters.

In the car enthusiast circle of modifications, the choice of engine oil for the 274 engine is a hot topic. I conducted a comparative test with my own C200: 0W-40 offers better low-temperature fluidity, enabling cold starts in just two seconds at -25°C; while 5W-40 provides more stable high-temperature protection, keeping oil temperatures 5 degrees lower during track runs. I now consistently use Shell Helix 0W-40, the version with Mercedes-Benz 229.52 certification. During a long-distance rally, it endured 8 hours of continuous high-load operation without triggering any oil pressure warnings. For daily commuting, semi-synthetic oil might suffice, but turbocharged cars are better off with full-synthetic oil.
