Engine Oil and Filter Specifications
The heart of the 2016 Mercedes-Benz CLA250 is the 2.0-liter four-cylinder engine with a turbocharger, identified by engine code 270.920 L Turbo. This high-performance unit generates significant heat and relies on precise oil flow to lubricate the turbo bearings and maintain valve train integrity. Selecting the right oil grade is critical for both cold-weather starting and high-temperature performance. For this vehicle, the recommended oil viscosities include 0W-30, 0W-40 for all temperatures, and 5W-30 or 5W-40 for operating temperatures above -25°C.
The engine oil capacity for the 2016 CLA250, when including a filter change, is 5.9 quarts. It is essential to pour the correct amount and then check the oil level after refilling to ensure it is within the safe operating range. The oil drain plug torque specification is 22 ft-lbs; adhering to this prevents leaks or thread damage. While AMSOIL does not currently recommend a specific oil filter for this model, using high-quality filter media with your choice of AMSOIL 5W-40 FS or AMSOIL 0W-40 FS synthetic oil ensures maximum contaminant retention and flow efficiency.
AMSOIL FS 100% Synthetic European Motor Oil is the top recommendation for this engine. Whether you choose the 5W-40 FS or the 0W-40 FS, you are utilizing a European formula that features a precise blend of synthetic base oils and premium additives. These oils are designed to meet the rigorous standards of gasoline, diesel, and hybrid European vehicles, providing protection against sludge, deposits, and high-temperature breakdown. This is particularly important for the CLA250, where the turbocharger pushes the engine to higher RPMs and temperatures than a standard naturally aspirated engine.
Transmission and Differential Fluids
The 2016 Mercedes-Benz CLA250 is equipped with an automatic transmission that requires a specific fluid to ensure smooth shifting and long-term durability. While specific transmission fluid recommendations and filter options are not currently available in the fitment data for this vehicle, maintaining the fluid at the correct level and interval is vital. The transmission system in this compact luxury sedan handles the power of the turbocharged engine, and using a fluid that resists thermal breakdown and wear is necessary for consistent performance.
Regarding the differential and transfer case, the data indicates a rear capacity of 1.6 pints. This small volume suggests a limited-slip or specific gearing setup common in this class of vehicle. Proper lubrication of the differential is essential for reducing friction between the gears and preventing premature wear. Although no specific AMSOIL differential fluid is listed in the current recommendations for this application, ensuring the differential is filled to the correct capacity with the appropriate grade of gear lubricant is a key maintenance task.
Cooling System and Brake Fluid
The cooling system in the CLA250 plays a crucial role in managing the heat generated by the engine and the turbocharger. The system has a capacity of 8.2 quarts. For this application, AMSOIL offers two distinct coolant options. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a poly-organic acid (OAT) formulation that comes as a 50/50 pre-mix, making it convenient for immediate use. It protects against corrosion and is compatible with all cooling system metals, gaskets, and hoses.
For owners who prefer to mix their own coolant, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a concentrated solution. This product requires mixing with distilled or high-quality water and provides extended protection up to 150,000 miles or 5 years. It is free of phosphates, nitrates, nitrites, silicates, borates, and amines, making it safe for all cooling system components. Both coolants are designed to prevent the degradation that leads to overheating, a common issue in high-output turbo engines if the cooling system is neglected.
Brake performance is paramount in a vehicle like the CLA250, which is designed for dynamic driving. The brake fluid specification calls for DOT 4 Plus, or products approved on MB Sheet 331.0, such as the specific codes 0009895605090109 (previously 0009895605110111 and 000989080701). The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid meets these requirements. It is engineered to provide excellent responsiveness for ABS and traction control systems. Unlike conventional glycol-based fluids, this synthetic fluid resists moisture absorption and maintains its viscosity over a wide temperature range, ensuring consistent braking power even under heavy use.
Seasonal and Performance Additives
Beyond the essential fluids that keep the engine running, the 2016 CLA250 can benefit from specialized additives designed to enhance performance and protect the vehicle during storage. For owners who store their vehicles or want to maintain peak fuel system efficiency, AMSOIL offers several additives. The AMSOIL P.i.® Performance Improver Gasoline Additive is a powerful option that can restore up to 14% horsepower and clean GDI fuel injectors back to 100% flow rate. This additive also helps prevent carbon buildup and controls pre-ignition knock, which is beneficial for direct injection engines like the CLA250’s.
For those looking to protect the upper cylinder components, the AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor provides essential lubrication to the fuel system and upper cylinders. It is compatible with capless fuel systems and helps prevent corrosion. If the vehicle will be stored for an extended period, the AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing varnish and gum buildup and fighting ethanol corrosion. Additionally, the AMSOIL Engine Fogging Oil can be used to protect internal engine components from rust and corrosion during long periods of inactivity.
Vehicle Care and Protection
Maintaining the exterior and interior of the CLA250 is just as important as the mechanical maintenance. The AMSOIL product line includes a variety of car care items designed to keep the vehicle looking pristine. For cleaning, the AMSOIL Engine Degreaser is a professional-strength formula that quickly removes grease, dirt, and grime from engine surfaces. The AMSOIL Heavy-Duty Degreaser is effective for dissolving oil and tar from various surfaces. For general washing, the AMSOIL High-Foam Car Shampoo provides a hard-on-dirt, gentle-on-coating clean, while the AMSOIL Miracle Wash Waterless Wash and Wax Spray offers a quick, soap-free wash that leaves a protective finish.
To protect the vehicle’s finishes, the AMSOIL Exterior Ceramic Spray provides a water-shedding layer that protects against UV rays. The AMSOIL Interior Detailer, available in Light Lemon or Scent Free, offers multi-surface cleaning with 90-day UV protection and odor elimination. For wheel and brake component maintenance, the AMSOIL Brake and Parts Cleaner quickly removes brake dust and contaminants without leaving residue, helping to eliminate brake squeal.
