Maintaining the 2009 Mercedes Benz B200 with a 2.0L turbocharged engine (Engine Code 266.980 B) requires lubricants that meet rigorous German engineering standards. This compact hatchback was designed with precision components that rely on high-quality synthetic fluids to handle the heat generated by the turbocharger and to ensure smooth shifting in its specialized automatic transmission. Using the correct viscosity and formulation is essential for preserving the longevity of the engine’s internal components, the transmission’s hydraulic system, and the braking system, which operates on strict DOT 4 specifications. AMSOIL synthetic lubricants are engineered to exceed these original equipment requirements, offering superior protection against wear, sludge, and extreme temperature fluctuations, ensuring your B200 remains responsive and reliable for years to come.

Proper lubrication is the foundation of mechanical reliability for the 2009 Mercedes Benz B200. The vehicle’s engine, a 2.0-liter four-cylinder with the 266.980 B turbo configuration, generates significant heat under load. Standard mineral oils may break down under these conditions, leading to increased wear on the turbocharger bearings and piston rings. By utilizing AMSOIL 0W-30 MS 100% Synthetic European Motor Oil, you provide a fluid that resists thermal breakdown and maintains its viscosity. This oil is designed for the unique demands of European vehicles, utilizing a precise blend that ensures the turbocharger receives adequate lubrication even during cold starts, while also protecting against the formation of sludge and deposits that can clog oil passages.
The capacity for the engine oil system is 5.3 quarts when including the filter replacement. It is crucial to adhere to this specification and check the oil level after the refill to ensure optimal protection. Additionally, the oil drain plug should be torqued to 22 ft-lbs to prevent leaks or damage to the drain plug threads. The oil filter recommendations for this specific engine model are currently unavailable in standard guides, suggesting that owners should rely on high-efficiency filtration systems that maximize oil flow and contaminant removal to complement the synthetic base oil.
Transmission and Cooling System Care
The transmission in the 2009 B200 requires a fluid that can handle the specific hydraulic pressures and friction requirements of the 722.8 series transmission. For the automatic transmission, the total fill capacity including the cooler is 6.9 quarts. However, for specific refill scenarios, the capacity may be 6.6 quarts for a total fill or 6 quarts for an initial fill, depending on whether the converter is being refilled. AMSOIL offers two primary options for this application. The Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is ideal for owners seeking the highest level of performance, providing reserve protection during heavy use and remaining fluid in sub-zero temperatures. Alternatively, the OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid offers a robust solution that resists harmful sludge and promotes smooth, shudder-free shifts.
The cooling system for this vehicle holds a capacity of 9 quarts. Maintaining the correct coolant mixture is vital to prevent overheating and corrosion. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix formulation of ethylene glycol that protects all cooling system metals, gaskets, and hoses. It is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, ensuring compatibility with various engine materials. For those preferring a concentrated option, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers extended service intervals up to 150,000 miles or 5 years. This concentrate requires mixing with distilled or high-quality water and provides superior protection against corrosion and erosion, making it a durable choice for the B200’s cooling system.
Brake Fluid and Fluid Additives
Braking safety is paramount in any vehicle, especially in a performance-oriented compact like the B200. The recommended brake fluid for this model is DOT 4 plus, specifically products approved on Mercedes-Benz Sheet 331.0. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid meets these stringent requirements. It provides excellent responsiveness for both ABS and traction control systems, maintaining a stable viscosity across a wide temperature range. This ensures that the brake pedal feel remains consistent and reliable, regardless of driving conditions or ambient temperature.
For owners looking to maximize fuel economy and restore engine performance, AMSOIL P.i.® Performance Improver Gasoline Additive is a valuable addition to the maintenance regimen. This additive can restore up to 14% horsepower and brings GDI fuel injectors back to 100% flow rate after just one tank of treated fuel. It helps prevent carbon rap and controls pre-ignition knock, which is particularly beneficial for turbocharged direct-injection engines. Additionally, the AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor works to lubricate the fuel system and upper cylinders, compatible with capless fuel systems, ensuring that the engine runs smoothly and efficiently.
Vehicle Background and Model History
Produced by Mercedes-Benz from 2005 to 2011, the B-Class (W245 platform) introduced a revolutionary concept to the compact car segment: a “compact sports utility.” The 2009 B200, equipped with the 2.0L turbocharged M266 engine, exemplified the brand’s commitment to combining practicality with dynamic driving characteristics. Unlike traditional hatchbacks, the B-Class featured a tall, wagon-like roofline and a flexible interior that offered seating for five, along with generous cargo capacity when the rear seats were folded down. This unique design made it a favorite among city dwellers and families who needed maneuverability without sacrificing utility.
The B200 model specifically, with its turbocharged four-cylinder engine, was designed to deliver spirited performance that belied its modest size. The 2.0L engine provided ample power for urban acceleration and highway merging, while the efficient transmission ensured a smooth ride. The vehicle’s reputation is built on its robust build quality and the precision engineering that is synonymous with the Mercedes-Benz brand. It occupies a unique market position as a premium compact MPV, offering a driving experience that is more engaging than typical economy cars. The B200’s design, with its distinctive “face” and sleek lines, made it a standout in the crowded compact market, appealing to those who valued style, safety, and driving dynamics in a single package.
Maintenance and Long-Term Performance
Extending the service life of the 2009 B200 relies heavily on the quality of the fluids used during routine maintenance. Synthetic lubricants significantly outperform conventional oils in terms of thermal stability, oxidation resistance, and film strength. By choosing AMSOIL synthetic products, owners can extend the intervals between oil changes, reduce engine wear, and improve fuel efficiency. The comprehensive range of recommended fluids covers every aspect of the vehicle’s lubrication needs, from the engine and transmission to the braking system and cooling loop. This holistic approach to maintenance ensures that all moving parts are protected against wear and corrosion, preserving the vehicle’s value and reliability for the long haul.
For those who engage in seasonal storage or long periods of inactivity, AMSOIL offers specialized products such as the Gasoline Stabilizer, which keeps fuel fresh for up to 12 months, and the Engine Fogging Oil, which protects internal engine components from rust. Additionally, cleaning agents like the Power Foam® Carburetor and Induction-System Cleaner can help remove deposits from ethanol and degraded fuel, maximizing horsepower and restoring startability. By integrating these products into the maintenance schedule, B200 owners can ensure their vehicle remains in peak condition, ready for the road whenever they need it.
