Understanding the specific fluid requirements for this vehicle begins with the engine oil. The 2.0L turbocharged engine in the B200 operates under high thermal stress, making a high-quality synthetic oil essential for reducing friction and preventing deposits. The recommended viscosity for all temperature ranges is 0W-30, though 0W-40 is suitable for extreme conditions. In colder climates, the oil should be capable of flowing at -25°C. For temperatures above -20°C, 10W-40 is an acceptable alternative. The engine oil capacity, including the filter replacement, is 5.3 quarts. Proper maintenance requires checking the oil level after refilling and ensuring the oil drain plug is torqued to 22 ft/lbs to prevent leaks or stripped threads. This specific engine code benefits significantly from oils formulated for European standards, which often differ in additive packages compared to domestic formulations.
Transmission Fluid Specifications and Maintenance
The 2008 Mercedes-Benz B200 utilizes an automatic transmission with the 722.8 specification, which is sensitive to fluid quality and viscosity. Using a high-performance synthetic automatic transmission fluid helps maintain smooth shifting and protects the torque converter and valve body from wear. The total fill capacity for the 722.8 transmission varies depending on whether the cooler is included. For a total fill including the cooler, the capacity is 6.9 quarts. A standard total fill requires 6.6 quarts. When performing an initial fill or a partial refill, the capacity drops to 6 quarts. Specifically, if refilling only the transmission, approximately 5.7 liters are needed, whereas refilling both the transmission and the converter requires 6.0 liters. The AMSOIL Signature Series Multi-Vehicle Automatic Transmission Fluid and the OE Multi-Vehicle Automatic Transmission Fluid are both suitable choices, designed to resist sludge formation and provide excellent cold-weather performance to ensure the transmission operates smoothly even in freezing conditions.
Cooling System Requirements
Adequate cooling is vital for the turbocharged engine in the B200 to prevent overheating and maintain power output. The cooling system capacity is substantial, requiring 9 quarts of Antifreeze & Coolant mixture. Owners have the choice between a pre-mixed formulation or a concentrate. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix made from ethylene glycol, offering immediate protection against corrosion, boiling, and freezing. It is phosphate, nitrate, nitrite, silicate, borate, and amine-free, ensuring compatibility with various vehicle metals. For those preferring a custom mix, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a concentrated option that must be mixed with distilled or high-quality water. This concentrate offers exceptional protection against metallic corrosion and erosion, extending service intervals significantly and surpassing standard industry requirements for longevity.
Brake Fluid and Safety Systems
Safety is paramount in a vehicle designed for urban agility and highway cruising. The braking system in the B200 requires a fluid that meets the high standards of Mercedes-Benz Sheet 331.0. The recommended specification is DOT 4 Plus, or specific part numbers such as 0009895605090109 (previously 0009895605110111) and 000989080701. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is fully compatible with these requirements. It provides a stable viscosity over a wide temperature range, which is crucial for consistent pedal feel and responsive ABS activation. Unlike conventional fluids that can absorb moisture and lower the boiling point over time, synthetic brake fluid resists moisture absorption, ensuring long-term safety and reliability for the brake system.
Additional Fluid Protection and Maintenance
Beyond the critical powertrain fluids, maintaining the vehicle involves attention to fuel system health and external protection. For seasonal storage, AMSOIL Gasoline Stabilizer can keep fuel fresh for up to 12 months, preventing varnish and gum buildup that can clog GDI injectors. AMSOIL P.i.® Performance Improver Gasoline Additive is highly effective for restoring horsepower and flow rates in fuel injectors, particularly in modern direct-injection engines. Additionally, AMSOIL Engine Fogging Oil can be used to protect internal components during extended periods of inactivity. For exterior care, heavy-duty metal protectors can shield the undercarriage from salt and moisture, while Silicone Spray helps maintain rubber seals and hoses without attracting dust. Using a comprehensive fluid care regimen ensures the vehicle remains in top mechanical condition.
